Food and Water Safety While Traveling
Trying local food is one of the best parts of travel ↗. A street stall, small family restaurant, local market, or regional dish can become one of the memories you bring home. But food and drinking-water standards are not the same everywhere, and your body may also be exposed to bacteria, viruses, parasites, or other hazards it does not normally encounter.
When I plan a trip, I do not avoid local food or assume that expensive restaurants are automatically safer. I check the destination’s current health guidance first, learn whether tap water needs extra care, and then use a few simple habits while eating. I pay attention to how food is cooked, whether it is served hot, how drinking water is handled, and whether something has been sitting out for a long time. That lets me enjoy local food without turning every meal into a safety check.
This guide explains food and water safety while traveling, especially for beginners going abroad. It covers drinking water, bottled water, ice, street food, restaurants, buffets, raw food, fruit and vegetables, hand hygiene, and what to do if you develop stomach problems. CDC guidance says contaminated food or drinks can cause travelers’ diarrhea and other illnesses, while WHO reports that unsafe food can carry bacteria, viruses, parasites, and chemical hazards.
Health Note: Food and water risks vary by destination. Check current CDC Travelers’ Health guidance or the relevant health authority for the country you are visiting, especially if you are pregnant, immunocompromised, traveling with young children, or managing a medical condition.
Key Takeaways
Check destination-specific food and drinking-water advice before departure.
Do not assume tap water is safe just because local residents drink it.
Where water safety is uncertain, factory-sealed bottled drinks are usually a simpler choice.
Remember that ice can carry the same risk as the water used to make it.
Prefer food that is thoroughly cooked and served hot when extra precautions are needed.
Be more careful with raw meat, seafood, salads, cut fruit, and uncooked sauces in higher-risk settings.
Wash your hands before eating, or use hand sanitizer containing at least 60% alcohol when soap and water are unavailable.
Judge street food by the same safety principles you use for restaurants.
If diarrhea becomes severe, prolonged, bloody, or is accompanied by concerning symptoms, seek medical care.
Why Food and Water Safety Matters While Traveling
Foodborne illness can happen at home or abroad, but travel can expose you to different sanitation systems, food-handling practices, water quality, and microorganisms.
Travelers’ diarrhea is one of the best-known examples. CDC says bacteria are the main cause of travelers’ diarrhea, although viruses and parasites can also cause it. Food and drinks contaminated with fecal matter are common routes of exposure.
Unsafe food can also spread illnesses beyond ordinary diarrhea. WHO states that contaminated food can cause more than 200 diseases, ranging from diarrheal illnesses to more serious infections and chemical-related health problems.
This does not mean you should be afraid of eating abroad.
The better approach is to identify when extra care makes sense and make choices that reduce avoidable exposure.
Check the Food and Water Situation Before You Travel
Do not use one global rule for every country.
Drinking-water safety and food-related illness risks can vary greatly between destinations and sometimes even between regions of the same country.
Before departure, check your destination through an official travel-health source. CDC maintains country-specific Travelers’ Health pages that can identify diseases linked to contaminated food or water and give destination-specific prevention advice.
Look for answers to questions such as:
Is tap water considered safe for travelers?
Are there current food- or water-related health notices?
Are certain diseases linked to contaminated food or water reported there?
Does CDC recommend avoiding untreated water?
Are there special precautions for the areas you plan to visit?
Do this before arriving rather than trying to judge water quality by looking at it.
Clear water can still contain organisms that can make you sick.
Can You Drink Tap Water While Traveling?
Sometimes yes. Sometimes no.
There is no rule saying travelers should avoid tap water everywhere outside the United States.
Instead, check reliable destination guidance.
In places where water treatment and sanitation are reliable, normal tap water may be suitable for drinking. In destinations where water quality is uncertain or official advice recommends precautions, choose a safer source.
CDC’s Yellow Book says water can carry many of the same organisms responsible for travelers’ diarrhea, including bacteria, viruses, and protozoa.
If official advice tells travelers to avoid tap water, apply that advice consistently rather than drinking it because it looks clean.
What Water Is Safer to Drink?
Where drinking-water safety is uncertain, CDC recommends beverages from unopened factory-sealed containers as a safer choice. Properly treated water may also be used when bottled water is unavailable.
Depending on the destination, safer options may include:
Factory-sealed bottled water
Properly boiled water
Water treated with a suitable filtration or disinfection method
Factory-sealed canned or bottled drinks
Hot drinks made with water that has been properly boiled
Check the seal on bottled water before drinking it.
If the cap appears loose, broken, or previously opened, choose another bottle.
In places where travelers commonly rely on bottled water, buy it from established shops, hotels, restaurants, or other sources you trust.
Be Careful with Ice
Ice is easy to forget.
If unsafe water is used to make ice, freezing it does not automatically make it safe.
CDC advises travelers to avoid ice in destinations where drinking-water safety is uncertain unless they know it was made with safe water.
That means a cold drink can create a water exposure even when you never drink from the tap.
If local guidance recommends avoiding tap water, ask whether ice is made from purified or treated water before using it.
Factory-made ice may be commonly safe in some destinations, while the situation may be different elsewhere.
Again, follow the destination rather than a universal rule.
What About Brushing Your Teeth?
If official advice says local tap water should not be consumed, it can make sense to use safe water for brushing your teeth as well.
CDC’s Yellow Book advises travelers in areas with unsafe water to avoid getting potentially contaminated water in the mouth during activities such as brushing teeth.
Keep a bottle of safe water near the sink if that helps you remember.
This is a small habit that is easy to overlook after a long travel day.
Be Careful with Water Used for Baby Formula
Traveling with an infant requires more care because water may be used to prepare formula.
Use water that meets current health guidance for the destination and follow safe infant-feeding instructions.
Children can become dehydrated faster than many adults during diarrheal illness, so food and water precautions deserve extra attention when traveling with infants or young children. CDC’s Yellow Book advises adults to make sure traveling children follow safe food and water precautions and frequent hand hygiene.
If you are unsure about preparing formula safely at your destination, ask a qualified healthcare professional before departure.
Be Careful with Water From Natural Sources
A clear mountain stream or lake should not automatically be treated as drinking water.
Natural water can contain microorganisms even when it looks clean.
CDC’s water-disinfection guidance explains that untreated water can carry bacteria, viruses, and protozoa and discusses boiling, filtration, and chemical disinfection methods for travelers who cannot access safe drinking water.
If you are hiking, camping, or visiting a remote area, plan how you will obtain or treat drinking water before you leave.
Do not rely on appearance, smell, or taste alone.
Avoid Floodwater and Questionable Recreational Water
Water safety also matters when you are not drinking it.
CDC advises avoiding swimming or wading in water that looks contaminated, smells bad, contains visible algal material, or has recently been affected by heavy rainfall in situations where contamination may be present.
Destination-specific health guidance may also warn travelers about freshwater exposure when diseases such as leptospirosis or other water-related infections are present.
If floods, storms, sewage problems, or other local events affect water conditions, follow current local health advice rather than your normal swimming plans.
Choose Food That Is Cooked and Served Hot
One of the simplest food-safety habits while traveling is choosing food that has been properly cooked and is still hot when served.
CDC recommends eating food that is cooked and served hot in places where travelers need food precautions.
That does not mean every lukewarm dish will make you sick.
The reason hot, freshly cooked food is often the better choice is that you have more information about its recent preparation than food that may have been sitting at an unsafe temperature for a long time.
When extra precautions are needed, I would generally choose food that is cooked in front of me or arrives clearly hot rather than food that has been sitting uncovered for an unknown period.
Be Careful with Buffets
Buffets can create a food-safety issue when cooked food sits for a long time without suitable temperature control.
CDC advises travelers to avoid food that has been sitting on a buffet when following food and water precautions.
You do not need to avoid every hotel breakfast buffet.
Look at the setup.
Ask yourself:
Is hot food actually hot?
Is cold food being kept cold?
Is food protected from handling and insects?
Does it look freshly replenished?
Has it been sitting in the sun or heat?
If something looks like it has been sitting for a long time, choose another option.
Be More Careful with Raw or Undercooked Food
Raw or undercooked food can carry organisms that proper cooking may reduce.
CDC advises travelers following food precautions to avoid raw or undercooked meat and seafood. It also specifically notes that seafood treated with citrus juice or other acidic liquids, such as ceviche, is still considered raw rather than fully cooked by heat.
Extra care may be sensible with:
Raw meat
Undercooked poultry
Raw shellfish
Raw seafood
Undercooked eggs
Raw dishes prepared from animal products
The level of risk depends on the food, preparation, destination, and individual traveler.
If you are unsure how something was prepared, ask.
What About Sushi and Raw Seafood?
Sushi and other raw seafood dishes can be part of local food culture, but raw seafood carries different food-safety risks from fully cooked seafood.
That does not mean travelers must avoid sushi everywhere.
Consider:
The destination
The restaurant
Food handling
Cold storage
Your own health risk
Current official health guidance
Travelers at higher risk of severe foodborne illness may need stricter precautions and should follow medical advice specific to them.
For beginners in a destination where CDC recommends stronger food precautions, fully cooked seafood is the simpler lower-risk choice.
Be Careful with Raw Fruit and Vegetables
CDC advises travelers in higher-risk settings to eat raw fruits and vegetables only when they have washed them with safe water or peeled them themselves.
Whole fruits you peel yourself can be easier to judge because you control the final preparation.
Examples include:
Banana
Orange
Mango
Avocado
Pre-cut fruit deserves more care because you may not know:
Which water was used
Whether the knife or cutting surface was clean
How long the fruit has been sitting?
How it was stored
CDC specifically advises avoiding cut-up fruits and vegetables when food precautions are needed because contamination can occur during preparation.
Salads Can Carry Extra Risk in Some Destinations
Salads are another food that may look safe because they are fresh.
But uncooked vegetables may have been washed with contaminated water or exposed to contamination during preparation.
CDC advises travelers following stronger food precautions to avoid fresh salads, including shredded salads, in settings where contamination is a concern.
This does not mean salad is unsafe everywhere abroad.
If the destination has reliable water and food sanitation, normal eating practices may be fine.
The key is matching your precautions to local conditions.
Raw Sauces and Condiments Can Be Easy to Forget
Fresh salsa, chutneys, garnishes, and sauces made from uncooked fruits or vegetables may carry similar risks to salads.
CDC specifically includes fresh salsas, condiments, and raw fruit or vegetable sauces among foods to avoid where stronger food precautions are needed.
Travelers often focus on the main meal and forget the small bowl placed beside it.
If you are following food precautions at a destination, apply the same rule to raw garnishes and sauces.
Street Food Is Not Automatically Unsafe
Street food is one of the areas where travel advice can become too simple.
CDC’s public traveler guidance says avoiding street-vendor food is the lowest-risk option in settings where food precautions are needed. It also says that travelers who choose street food should apply the same rules used elsewhere, such as choosing food cooked thoroughly and served steaming hot.
So the useful question is not:
Is street food safe?
It is:
How is this particular food being prepared and handled?
If I choose street food, I pay attention to whether the food is cooked fresh, served hot, and handled in a way that makes sense. I would be more cautious with raw garnishes, food sitting uncovered for a long time, or items prepared with water whose safety I cannot judge.
Street food should not get a free pass because it is popular, but it also should not be treated as dangerous simply because it is sold outdoors.
Look Beyond How Busy a Restaurant Is
A busy restaurant can be a useful sign that food moves through the kitchen quickly, but popularity alone does not prove good hygiene.
Pay attention to what you can actually observe:
Is cooked food served hot?
Is cold food being kept cold?
Do staff handle money and food without washing or changing gloves where appropriate?
Are raw and cooked foods kept apart?
Does food appear freshly prepared?
Are eating areas reasonably clean?
Is food protected from insects and unnecessary handling?
WHO’s Five Keys to Safer Food focus on keeping food clean, separating raw and cooked items, cooking thoroughly, keeping food at safe temperatures, and using safe water and ingredients.
You will never be able to inspect a restaurant kitchen while traveling.
The goal is to notice obvious warning signs and make a sensible choice with the information available.
Do Not Assume Expensive Food Is Safer
Food price and food safety are not the same thing.
An expensive restaurant can make food-handling mistakes, while a simple local stall may cook one dish continuously and serve it immediately.
CDC notes that some food-safety factors, including restaurant hygiene, are outside a traveler’s control. Even careful travelers cannot remove every risk.
Instead of judging food by price, look at:
Preparation
Cooking
Storage
Temperature
Cleanliness
Water used
How long the food has been sitting
That is more useful than assuming a higher bill guarantees safer food.
Be Careful With Unpasteurized Dairy Products
Milk and dairy products deserve attention in places where pasteurization cannot be confirmed.
CDC advises travelers following stronger food precautions to choose pasteurized milk and dairy products and avoid unpasteurized products.
This may apply to:
Milk
Cheese
Yogurt
Ice cream
Other dairy products
Do not assume something is pasteurized because it is sold in a shop or restaurant.
If you are unsure and the destination has known food-safety concerns, choose an option you can verify more easily.
Be Careful With Eggs
Egg dishes can be another source of foodborne illness if they are raw or undercooked.
When stronger food precautions apply, choose eggs that are cooked thoroughly rather than dishes containing runny or raw egg.
This can matter in:
Breakfast dishes
Desserts
Homemade sauces
Dressings
Drinks containing raw egg
CDC food-safety guidance treats eggs alongside meat, poultry, and seafood as foods that can spread germs when raw or undercooked.
Again, the aim is not to remove eggs from your trip. It is to pay attention to preparation.
Wash Your Hands Before Eating
Hand hygiene is one of the simplest travel food-safety habits.
CDC advises washing hands with soap and water before eating and before preparing food. When soap and water are not available, it recommends an alcohol-based hand sanitizer containing at least 60% alcohol.
Wash your hands especially after:
Using the restroom
Using public transportation
Handling money
Visiting markets
Touching animals
Changing a child’s diaper
Returning from crowded attractions
Carrying a small hand sanitizer can be useful when you are eating somewhere without easy access to a sink.
But use soap and water when they are available.
Be Extra Careful After Using the Restroom
Foodborne and waterborne infections can spread through poor hand hygiene.
Wash your hands thoroughly after using the restroom and before touching food.
This matters even if the restaurant itself appears clean.
Your own hands have been touching:
Door handles
Phones
Railings
Ticket machines
Cash
Public transport
Shared surfaces
Food safety while traveling is partly about the restaurant and partly about what you do before the food reaches your mouth.
Keep Your Phone Away While Eating When Practical
Phones travel everywhere with us.
They are placed on:
Train seats
Airport counters
Restaurant tables
Hotel surfaces
Public benches
Then we touch them while eating.
You do not need to disinfect your phone before every meal, but washing your hands and then immediately handling a dirty phone can undo some of that benefit.
If you have just cleaned your hands before eating, avoid unnecessary handling of shared or dirty surfaces until you finish.
This is a small habit, but it is easy to apply.
Take Extra Care When Preparing Your Own Food
Staying in an apartment, hostel, campsite, or vacation rental may mean preparing some meals yourself.
Use the same basic food-safety principles you would at home.
WHO’s guidance can be reduced to five practical habits:
Keep preparation areas and hands clean.
Keep raw foods away from cooked or ready-to-eat foods.
Cook food thoroughly.
Keep food at suitable temperatures.
Use safe water and ingredients.
CDC also advises keeping raw meat, poultry, seafood, eggs, and their juices separate from other foods to reduce cross-contamination.
If you cannot tell whether a refrigerator is staying cold enough or food has been left out for an unknown period, choosing something freshly prepared may be safer.
Be Careful With Leftovers
Travel days make leftovers tempting.
You may order too much food at dinner and want to save the rest for later.
The question is how the food will be stored.
Food that needs refrigeration should not spend long periods sitting:
In a hot hotel room
Inside a backpack
In a parked car
On a beach
On a long bus ride
If your accommodation does not have suitable cold storage, keeping certain leftovers for the next day may not make sense.
This is especially relevant in hot destinations where food can warm quickly.
When you are unsure how long food has been unrefrigerated, replacing one meal is usually better than gambling with the rest of your trip.
Be Careful at Traditional Food Markets
Food markets can be excellent places to experience local ingredients and cooking.
They can also contain raw meat, seafood, live animals, prepared foods, and large numbers of people within a small space.
WHO’s guidance for traditional food markets emphasizes cleanliness, avoiding contamination, keeping food products safe, reducing unsafe animal contact, and protecting yourself while visiting.
At markets:
Avoid touching raw meat or animal products unnecessarily.
Wash or sanitize your hands before eating.
Keep ready-to-eat food away from raw-food surfaces.
Choose cooked food that is served hot where stronger precautions apply.
Avoid food that appears poorly stored.
Follow local public-health instructions during outbreaks.
Enjoy the market, but do not treat every sample or raw item as automatically safe because it is part of the local experience.
Avoid Bushmeat
CDC advises travelers not to eat bushmeat, meaning wild animals not normally used as food in the United States, such as bats, monkeys, or certain rodents.
Such meat can be linked to diseases that spread from animals to humans.
This is different from ordinary locally raised meat or properly regulated game.
If you cannot identify what an animal product is or where it came from, do not feel pressured to eat it just to prove you are adventurous.
Food Allergies Need Their Own Preparation
Food safety is not only about infection.
For travelers with food allergies, an unfamiliar language, cuisine, or preparation method can make ingredient checking harder.
Before departure, learn how to clearly explain your allergy in the local language where useful.
Consider carrying:
Written allergy information
Translation card
Prescribed emergency medication
Information about cross-contact risks
Do not assume a familiar-looking dish contains the same ingredients used at home.
Sauces, cooking oils, garnishes, spice mixes, desserts, and shared cooking equipment can introduce ingredients that are not obvious from the menu.
If your allergy can cause a severe reaction, discuss travel preparation with your healthcare professional before departure.
What Is Travelers’ Diarrhea?
Travelers’ diarrhea is a common travel-related illness usually acquired through contaminated food or drinks.
CDC says bacteria cause most cases, while viruses and parasites can also be responsible.
Symptoms can include:
Loose or watery stools
Abdominal cramps
Nausea
Urgency
Vomiting in some cases
Fever in some infections
Not every episode of stomach discomfort during travel is travelers’ diarrhea.
Changes in diet, alcohol, stress, jet lag, and unfamiliar foods can also affect digestion.
But repeated diarrhea deserves attention because fluid loss can lead to dehydration.
The First Priority Is Replacing Lost Fluids
If diarrhea begins, avoiding dehydration becomes one of the main concerns.
CDC’s Yellow Book identifies fluid replacement as a key part of managing travelers’ diarrhea. Oral rehydration solution can be especially useful when fluid loss is significant.
Drink safe fluids regularly.
For mild illness, normal safe drinks may be enough.
With heavier fluid loss, oral rehydration solution can help replace both water and electrolytes.
Follow the package directions and prepare it using safe water.
Do not guess at homemade concentrations if a proper oral rehydration product is available.
Be Careful With Very Sugary Drinks During Diarrhea
Replacing fluids is useful, but very sweet drinks in large amounts may make diarrhea worse for some people because of their sugar content.
CDC’s travelers’ diarrhea guidance favors oral rehydration solution for significant fluid loss because it is formulated for rehydration.
If you are becoming dehydrated, especially after repeated diarrhea or vomiting, use appropriate rehydration rather than depending only on soda or very sugary drinks.
Watch for Signs of Dehydration
Diarrhea and vomiting can remove water and electrolytes quickly.
Possible warning signs include:
Strong thirst
Dry mouth
Reduced urination
Dark urine
Weakness
Dizziness
Young children, older adults, and people with certain health conditions can become more affected by fluid loss.
CDC identifies dehydration as one of the severe features that should prompt medical attention in travelers with diarrhea.
If you cannot keep fluids down or signs of dehydration are becoming significant, seek medical help.
Know When Travelers’ Diarrhea Needs Medical Care
Many mild cases improve without advanced medical treatment, but some symptoms deserve professional assessment.
CDC advises travelers to seek medical attention when diarrhea is particularly severe, includes high fever, dehydration, or blood, or when concerning symptoms persist.
Seek medical care sooner if you have:
Bloody diarrhea
High fever
Significant dehydration
Severe or worsening symptoms
Persistent vomiting that prevents drinking
Severe abdominal pain
Symptoms that continue rather than improving
People who are pregnant, immunocompromised, very young, older, or managing significant medical conditions may need earlier medical advice.
Do Not Automatically Take Antibiotics
Antibiotics are not appropriate for every episode of travelers’ diarrhea.
Different illnesses can cause similar symptoms, and unnecessary antibiotic use can create side effects and contribute to antimicrobial resistance.
CDC’s current Yellow Book guidance bases antibiotic use on illness severity and individual circumstances rather than recommending antibiotics for every case.
If a healthcare professional gave you a specific treatment plan before travel, follow those instructions.
Otherwise, do not buy random antibiotics from an unfamiliar pharmacy simply because you have diarrhea.
Seek qualified medical advice when treatment beyond hydration and basic self-care may be needed.
Be Careful With Anti-Diarrheal Medicines
Some travelers carry medicines such as loperamide for diarrhea.
These can be useful in certain situations, but they are not right for every illness.
CDC guidance does not recommend antimotility medicines alone for travelers with bloody diarrhea or diarrhea accompanied by fever.
If you have significant symptoms, seek medical advice instead of using medication only to continue sightseeing.
Before travel, you can ask a qualified healthcare professional what medicines, if any, make sense for your destination and health needs.
Persistent Diarrhea After Travel Needs Attention
Most short episodes end during the trip or soon afterward.
Diarrhea that continues for a longer period may have a different cause.
CDC notes that parasites become more likely among causes of persistent post-travel diarrhea, and infections such as Cryptosporidium can cause prolonged watery diarrhea.
If diarrhea continues after your trip, tell the healthcare professional that you recently traveled and where you went.
That travel history can help guide testing and treatment.
Do Not Swim While You Have Diarrhea
If you are sick with diarrhea, avoid swimming in pools, hot tubs, splash areas, lakes, or other recreational water.
CDC advises travelers not to enter recreational water while they have diarrhea because illness can spread to other people.
Rest and focus on recovery rather than trying to keep every planned activity.
Missing one swim is better than spreading an infection.
Food Poisoning Does Not Always Mean the Last Meal Caused It
If you become sick after dinner, it is tempting to assume dinner caused the illness.
But different foodborne infections have different incubation periods.
The food responsible may have been eaten earlier.
That means blaming a specific restaurant immediately can be misleading unless a healthcare or public-health investigation identifies the source.
Instead, focus first on:
Your symptoms
Hydration
Medical care if needed
What and where you ate
Whether other travelers are sick
Keeping a short record can be useful if symptoms become serious or several people in your group develop the same illness.
Keep Notes if Several People Become Sick
If multiple people who ate together develop similar symptoms, write down:
Restaurants visited
Foods eaten
Drinks consumed
Approximate meal times
When symptoms started
This information may help a healthcare professional or public-health authority.
Do not spend your trip trying to perform your own investigation.
Record what you know and seek proper help when symptoms warrant it.
Do Not Let Food Safety Stop You From Trying Local Food
The purpose of these precautions is not to turn every meal into packaged food from home.
You can still:
Visit markets
Try regional dishes
Eat at small local restaurants
Enjoy street food where you choose to
Try unfamiliar ingredients
Use a few consistent questions:
Was it cooked properly?
Is it being stored sensibly?
Is the water safe?
Are my hands clean?
Does this destination require stronger precautions?
That gives you a practical way to enjoy local food while reducing avoidable risks.
Common Food and Water Safety Mistakes Travelers Make
Many food-related problems come from small decisions rather than one obviously unsafe meal.
Assuming Clear Water Is Safe
Water can look, smell, and taste normal while still containing organisms that can cause illness.
Check destination-specific guidance instead of judging water by appearance. CDC notes that bacteria, viruses, and protozoa that cause intestinal illness can be carried through drinking water.
Forgetting About Ice
Travelers may avoid tap water but order several drinks containing ice made from the same water.
Where local drinking water requires extra precautions, check the source of the ice as well.
Eating Raw Garnishes Without Thinking About Them
You may carefully order fully cooked food and then add raw salad, herbs, salsa, or another uncooked garnish.
In destinations where stronger food precautions apply, these items deserve the same attention as other raw produce.
Thinking Expensive Restaurants Cannot Cause Foodborne Illness
Price does not tell you how food was stored, cooked, or handled.
Use the same basic safety habits in restaurants, hotels, markets, and food stalls.
Choosing Food That Has Been Sitting Out
Hot food should generally be served hot when you are following travel food precautions.
CDC advises travelers at higher-risk destinations to avoid food that has been sitting on buffets and to choose food cooked and served hot.
Drinking Bottled Water Without Checking the Seal
A bottle is more reassuring when the factory seal is still intact.
If a bottle appears previously opened or the cap looks unusual, choose another one.
Forgetting Water When Brushing Teeth
If destination guidance says the tap water should not go in your mouth, use safer water for brushing your teeth too.
Apply the same thinking to anything that may enter your mouth.
Depending on Hand Sanitizer for Everything
Hand sanitizer is useful when you cannot reach soap and water.
CDC recommends sanitizer containing at least 60% alcohol when handwashing is unavailable, but travelers should still wash with soap and water when possible.
Eating Food Just Because Other Tourists Are Eating It
A long queue can suggest fast food turnover, but it does not guarantee safe ingredients, water, cooking, or storage.
Look at the actual preparation.
Being Too Afraid to Eat Local Food
The opposite mistake also happens.
Some travelers avoid nearly every local meal because they are worried about becoming sick.
Food safety does not require eating packaged food for the entire trip. Use sensible precautions that match the destination and enjoy the food that makes sense for you.
A Simple Rule for Choosing Food While Traveling
When you are unsure about a meal, ask five questions:
Is It Clean?
Look at the preparation area and how food is being handled.
Is Raw Food Kept Away From Cooked Food?
Cross-contamination can transfer germs from raw ingredients to food that is ready to eat.
Is It Properly Cooked?
Fully cooked food is often easier to judge in destinations where extra precautions are recommended.
Is It Being Kept at a Suitable Temperature?
Be more careful with food that appears to have been sitting warm for a long time.
Is Safe Water Being Used?
Water matters for drinks, ice, washing produce, sauces, and food preparation.
These questions closely match WHO’s Five Keys to Safer Food: keep clean, separate raw and cooked foods, cook thoroughly, keep food at safe temperatures, and use safe water and ingredients.
Food and Water Safety Checklist for Travelers
Before Your Trip
Check official food and water guidance for your destination.
Find out whether tap water needs extra precautions.
Check current travel-health notices.
Pack any regular medication you need.
Carry hand sanitizer for times when soap and water are unavailable.
Consider carrying oral rehydration solution if it makes sense for your trip.
Discuss destination-specific health concerns with a healthcare professional when needed.
Drinking Water
Follow current local and official advice about tap water.
Choose unopened factory-sealed drinks where safer water is needed.
Check bottled-water seals.
Ask about ice if local water quality is uncertain.
Use safe water for brushing teeth when recommended.
Do not assume clear natural water is safe to drink.
Treat water correctly during remote trips when safe water is unavailable.
CDC advises travelers in higher-risk settings to choose factory-sealed beverages, avoid questionable ice, and use suitable treatment methods when safe drinking water is unavailable.
Choosing Food
Prefer food that is thoroughly cooked and served hot where stronger precautions apply.
Be careful with food that has been sitting on a buffet.
Take extra care with raw or undercooked meat and seafood.
Check raw fruit and vegetables carefully.
Peel fruit yourself where recommended.
Think about raw sauces, salads, and garnishes.
Choose pasteurized dairy products where needed.
Avoid food that appears poorly stored.
Judge street food by preparation rather than popularity alone.
At Restaurants and Food Stalls
Look at how food is being cooked and stored.
Check whether hot food is served hot.
Avoid obvious hygiene problems.
Keep raw food risks in mind.
Do not feel pressured to eat something you do not trust.
Wash or sanitize your hands before eating.
At Markets
Avoid unnecessary contact with raw animal products.
Wash your hands before eating.
Keep ready-to-eat food away from raw-food surfaces.
Be careful with uncooked samples where food precautions apply.
Follow current public-health advice during outbreaks.
If You Prepare Your Own Food
Wash your hands.
Keep raw and cooked foods separate.
Cook food properly.
Refrigerate foods that require cold storage.
Use safe water.
Keep preparation surfaces clean.
These steps follow WHO’s established safer-food principles.
If You Develop Diarrhea
Drink safe fluids.
Watch for dehydration.
Use oral rehydration solution when appropriate.
Rest rather than forcing your normal itinerary.
Seek medical help for severe or concerning symptoms.
Tell a healthcare professional where you traveled if symptoms continue after returning home.
CDC’s current Travelers’ Diarrhea guidance continues to place fluid replacement at the center of treatment and gives different medical advice based on illness severity.
Food Safety for Children While Traveling
Young children need extra attention because diarrhea and vomiting can lead to dehydration faster than they may in healthy adults.
Parents should make sure children:
Drink safe water
Follow destination food precautions
Wash their hands frequently
Avoid unsafe food and drinks
Receive medical help when symptoms become concerning
CDC specifically advises adults to make sure traveling children follow safe food and water precautions and frequent hand hygiene.
Traveling with children does not mean avoiding all local food.
Choose options that fit their age and the destination’s health guidance.
Food Safety for Older Travelers and People With Weakened Immune Systems
Some people face a higher chance of severe illness from foodborne infections.
CDC identifies young children, older adults, people with weakened immune systems, and international travelers among groups who may need greater care with certain foodborne infections.
If you have a medical condition or weakened immune system, ask a qualified healthcare professional whether you need stricter food precautions for the destination.
Do not rely only on general travel advice if your health situation changes the level of risk.
Do You Need to Pack Food From Home?
Usually, no.
Most travelers can find suitable food at their destination.
Bringing a small amount of familiar food can still be useful if you:
Have serious allergies
Have medical dietary needs
Travel with a young child
Are heading somewhere remote
Need food during a long transport day
Check customs and agricultural rules before carrying food across international borders.
Some countries restrict meat, fruit, seeds, dairy products, and other food items.
Should You Take Probiotics to Prevent Travelers’ Diarrhea?
Do not assume supplements can replace safe food and water habits.
Prevention should still focus on safer food choices, safe drinking water, and hand hygiene.
If you are considering probiotics, medication, or another preventive treatment for a specific health reason, discuss it with a qualified healthcare professional who can consider your health and destination.
Food and Water Safety Is About Reducing Risk, Not Removing Every Risk
Even travelers who follow every precaution can sometimes become sick.
CDC notes that travelers cannot completely control hygiene and food preparation in restaurants and other eating places.
That is why the goal should be realistic.
You can reduce avoidable exposure by:
Checking destination guidance
Drinking safer water
Choosing food carefully
Washing your hands
Paying attention to preparation
Knowing what to do if you become sick
You cannot inspect every kitchen or control every ingredient.
Good travel planning gives you better odds without making food the stressful part of your trip.
