One of the most frequent questions from readers is a straightforward one: how can I try foods from around the world and/or eat street food without getting sick? I got this query from readers in many different countries over the years, and it’s what led me to write a longer form book about that very topic.
Street food is such an integral part of why I travel, and a wonderful way to soak in the sights and sounds of the places I’m visiting. Given that my life for many years revolved around eating, this piece is long overdue.
I did not grow up obsessed with food, which is a surprise to many who read this site. People I meet nowadays laugh when I tell them that I used to see food as a simple necessity, not a joy. In my early 20s, however, I was diagnosed with celiac disease, which meant that I had to start paying attention to each ingredient as I ate. While traveling, this led to interacting differently with food vendors since I needed to ask many more questions in order to eat safely. What started as an obligation to keep me safe morphed not long thereafter into my present obsession with eating the world.
My food journey may have begun with restrictions on eating, but it inhabits a wide open space of curiosity. Food is the most intensive and rewarding lens I can use to learn about a new place, and staying curious about why dishes are prepared a certain way, or how ingredients are used, has led me to experience destinations differently.
While I always enjoyed my travels prior to eating my way through them, the feel of those years is less intense and colourful than what I feel about traveling through food. And even if eating obsessively isn’t your jam, it’s still important to make sure you try foods as safely as possible.
Which is why I finally sat down to write the post you have all been asking me for.
My tips for eating street food without getting sick
My pre-trip research for food simply consisted of reading a book called How to Shit Around the World, which I highly recommend doing on a crowded subway trip. The book has entertaining vignettes, practical advice, and a lot of tips about eating abroad. Despite consuming the book from start to finish, I went to South America and promptly ate a lukewarm llama empañada, and then threw up for 4 days straight as I crawled my way through the Salar de Uyuni in Bolivia.
“Ok,” I said to myself, “rule number 1 is do not eat your favourite animal when you eat street food.”
An acquaintance got sick in Chiang Mai recently and said, “but I didn’t even eat the street meat”. I shook my head in dismay. “That’s probably why you got sick!” Instead, he went to a tourist restaurant during off-peak hours. Two strikes against his stomach right there.
I realize people are worried about food poisoning, and the advice out there does seem to suggest restaurants are safer. I strongly disagree, with some caveats.
Once you know what to look for, pay attention to what locals eat and when, then you are on your way to successful, delicious meals that serve as experiences as well as dinner. No advice is a fail-proof method, but this is what has worked for me.
In my years of travel, I have fallen off a motorbike when a truck full of cabbages and pineapples rained vegetables down on me, gotten bronchitis, lung damage, a broken toe, and dengue fever. Not all at once, mind you. But they were difficult challenges, even when spaced out. Food poisoning, however, was very rare. In my decade of full-time traveling (at the time of updating this post), I got sick only a few times. The most recent one was when I ate a yoghurt at the 7-11 in Thailand in 2011, a full 12 years ago.
That’s right, I have not gotten food poisoning since 2011 despite eating street food all the time.
This feat includes street food in India during my 2013 trip there. Here’s what I did to eat street food without getting sick:
1. Check out the length of the lineups.
Everyone tells you to eat at the stalls with the longest line of locals. This is still good advice! But I always add that it’s important to look at who is in line. I know my stomach is potentially less resilient than that of a taxi driver used to quick street meats, so I try to opt for street stalls with both women and children in line.
More variety in the customer base usually means the stall has been vetted enough that it’s safe for everyone. Yes, it’s still better to choose a long lineup of men over crickets and an empty stall, but given the choice, women and children in line is where you want to go.
2. Go back to school at lunchtime.
For a cheap lunch, go to the local university and find a place nearby to eat. Students are a hungry bunch, and often some of the fun variations of east meets west pop up here. In Saigon, “pho burgers” were present but so were cheap stalls that served local favorites to a rotating cast of students. It won’t be the best meal of your life, but it will be local, fast, cheap, and usually delicious. Not recommended for dinnertime, however, as the meals will have sat out for the afternoon.
3. Take advantage of a transparent kitchen: street stalls!
As I said in the introduction, I feel like I have more control with a street stall because I can see how the food and the money is handled. If someone is touching the money and then the raw ingredients, I don’t eat there. If there are plastic gloves for the food-making and then they are kept on for handling money? Same – it’s a miss. For two-party stalls often one person will be in charge of the cash and cooking, and the other preparation. This is a good bet, since they are kept separate.
Basically, avail yourself of your senses when choosing where to eat.
That’s not to say that I avoid restaurants entirely! But where there is a culture of street food (like Mexico City or Saigon or Bangkok) I will usually eat all of my meals on the street.
4. Detailed translation cards for those with food allergies or restrictions.
I have celiac disease, and another reason I eat on the street is that I can modify the meal as it is cooked, instead of relying on pre-made sauces that might get me sick. I made my own translation cards because the ones I bought or downloaded still got me sick because they were insufficiently detailed. For example, many vendors don’t realize that soy sauce, hoisin sauce, and oyster sauce all contain wheat flour. Each card goes through two sets of translations and is researched by a celiac who loves to eat.
Friends with peanut allergies also carry translation cards, and of course due diligence is needed to know what ingredients have to be avoided. If you’re looking for nut allergy or shellfish allergy cards, you can head to Select Wisely or Equal Eats.
These cards go a long way toward getting your point across — certainly more so than my initial “gesture feverishly while mimicking getting ill over food” — and Select Wisely has a strongly worded option for those with more life-threatening allergies. You could also bring a Point It Dictionary if you’re concerned about eating food you can’t place. Also fun for trading words in your respective language when on a long train ride. I am also in the process of building my own celiac cards with highly detailed notes tailored to specific countries.
5. Cutlery as culprit for getting sick on the road.
Cutlery can be a source of bacteria even if the food is safe and fresh. I carry baby wipes with me for older wooden chopsticks that look like they need a wipedown, or for utensils that don’t seem well-washed. It will get you some weird looks but it can be helpful to ensure the cutlery is clean. Alternatively, cute portable chopsticks will do the trick. I carry these ones at all times.
I rarely make use of this extra cleaning-or-chopsticks system but have found it really useful to have the option, especially when outside of urban centers. A bonus: if you need to use the washroom and forgot toilet paper you always have your baby wipes!
6. Morning markets are a great way to start the day.
When readers write about where to start with street food, I always suggest they head to a busy local produce market. Be it the many rotating markets around Inle Lake in Myanmar to morning food markets in Mexico City, or on a side trip to a small village — if it has a produce market, it usually has some freshly cooked food. Because these stalls are set up to feed the hungry shoppers, there is quick turnover. I’ve found that a way to experience a daunting new food spectrum is to start at these markets and try the foods one by one.
Plus, many people opt for hotels with breakfasts included, or for a more Western breakfast of yoghurt and fruit. While that may be an option, I’d highly recommend dining at a market instead. If you love the food you try, you can ask the vendor where they are during the day, or if they don’t serve that food elsewhere, where they would suggest you try it instead.
All in all, markets are an excellent way to kickstart your tastebuds and all of your other senses.
I am not a morning person, but on my travels I become one because these markets are one of the most memorable, tasty, and interesting ways to spend a few hours of my time.
7. What time do locals eat? That’s when you want to be eating.
One of the pieces of advice I give to tourists, especially European ones who eat a bit later than North Americans, is to try to mimic the local food times for their meals. I realize that 6pm dinners or 11am lunches don’t fit the usual meal patterns for most, but it can be very helpful for your stomach if that’s when locals eat.
This is especially important when dishes are cooked and set out buffet style, as you’d want to eat them when they are fresh and before bacteria can form as the food cools. For me, this means shifting my meal times somewhat but it is worth it because the food is piping hot, newly cooked, and doesn’t get me sick.
8. Fully cooked food is safest, always.
Remember my llama empañada? Yup, I disregarded this advice entirely. The center of the snack was cold and I still finished it off. DON’T BE ME. If it’s not fully cooked and it’s supposed to be a hot meal, ask for it to be cooked a bit more.
I’ve gotten more adventurous over the years, eating raw shrimp dishes in Thailand and fresh herbs in places where I don’t know the water source. This has been a product of my own risks and my understanding of what my stomach can handle. Happily, even in North India I didn’t get sick, despite eating street food. Why? I made sure it was fully cooked, freshly made, and my mum and I also decided to stick to the meal times of locals. (I have to say I was a bit surprised as I anticipated getting sick at least once given the stories of my friends but happily I did not!)
9. Beware of ice or fruit shakes where water may be contaminated.
I order drinks with ice in Saigon or Bangkok, where filtered water is subsidized and available cheaply for the general population. I’ve also spent quite a bit of time in both cities and have never gotten sick from the water or ice. That said, when I travel outside the cities I try to avoid ice or fruit shakes with ice because I do not know how the ice was made. If there’s an easy thing to cut out where the water isn’t safe, ice is the first to go. Fruit shakes in Laos downed quite a few of my friends because the ice was not made from distilled water. Best to be sure, especially if you’re frequently on the move.
10. In some destinations, sticking to vegetarian dishes may be helpful.
In some destinations, I avoid meat if I am really concerned about food poisoning. When I took my mum to India, we ate street food but stuck to vegetarian eats for the most part. The times we did eat meat we were told we were taking a risk, but we decided to regardless because we were excited about the food. Even the most carnivore of friends tend to temporarily avoid meat in places where water is extremely contaminated.
11. Peel your fruit—or don’t eat it.
Unless you are used to a new place and its bacteria, I would only eat peelable fruit. Bananas, papaya, mango, rambutan, mangoesteens and more — there is no shortage of delicious fruit that has a peel, and your stomach will thank you. Avoid lettuce, or fruit with skin you eat (like apples). Strawberries, while tempting, ought to be avoided in countries with high pollution and a questionable water system.
12. Sauces can be a problem, especially if left unrefrigerated.
I love a good table condiment, but occasionally the sauces are what causes travelers some distress. The reason is that in many destinations they are kept at room temperature, meaning they can breed bacteria over time. I tend to gauge my sauce usage on the amount of consumption from other diners: if it’s a food where condiments are used liberally (e.g. bun rieu soup in Vietnam, where it would be blasphemous to skip adding wet chili paste), I go for it. If I can see crust on the side of the sauce, or a few drops are used at a time, I will take my time trying the salsas or sauces to ensure they are not unrefrigerated indefinitely.
I am currently in Oaxaca, Mexico, and I have eaten sauces for all my meals thus far without issue. I have also chosen places teeming with people and families, and watched almost everyone scoop liberal amounts onto their food.
What to do if you get food poisoning?
The tips above are not guarantees and even the most iron cast stomachs can be felled occasionally by a food misadventure. It is part and parcel of the risk inherent in traveling.
If you get food poisoning or a stomach illness, then a visit to a local doctor might be in order. Many of them are familiar with traveler’s diarrhea but also with any lingering viruses circulating in the region. I do not take Imodium unless and until I have an absolute emergency in the form of a long bus ride plus food poisoning.
I would caution against trying to rehydrate immediately with sweetened sport electrolyte drinks because I’ve found the high levels of sugar in those drinks actually make me feel worse if the bacteria are still in my system. Instead, I stick to a steady diet of oral rehydration salts, rice (bread is a substitute if you are not gluten-intolerant) and bananas. Hydrate as much as possible.
What do I pack to make my stomach feel better?
Here are some items I keep in my bag, no matter the destination.
Probiotics for Travel
I would also recommend traveling with probiotics that don’t need refrigerating. They have helped me get back on track the times I have been sick, and I feel better when I take them. For years, I used the extremely compact Hyperbiotics Pro-15 probiotics, time release pearl capsules that have accompanied me for years. They include some of the strains I wanted to be sure I got in my body. I realize not everyone is sold on probiotics and that’s fair, but as always I am sharing my experiences.
For people with allergies or histamine intolerance, I highly recommend this D-Lactate free shelf-stable formula, which helps downregulate mast cells. There are some probiotics strains that increase histamine, and others that reduce it. In a new environment, you want a reducer and this is a good blend.
For an overview of pros and cons of probiotics, see this piece by the University of California at Berkeley.
Activated Charcoal: a Traveler’s Best Friend
I use activated charcoal when I feel a bit queasy, if I’ve got a hangover, and if I ate gluten by mistake and want to do what I can to mitigate. It has helped me tremendously and I don’t leave home without it, even in North America.
You can get these on Amazon, at the 7-11 in Thailand, or at most natural health stores. I’ve picked more up in Mexico, Vietnam, Laos, and many other countries.
They’re very reasonably priced.
Digestive Enzymes for Travel
I find these useful for me as a celiac, but friends carry them also despite not having any food restrictions. I use this product because it has DPP-IV (Dipeptidyl Peptidase IV) in it, which helps break down gluten and casein. To be clear, I use these NOT to eat gluten but for times I mistakenly eat gluten and feel very sick. (It is essentially an emergency tool for me; there is no fix for the disease). For non-celiacs a general digestive enzyme like this would normally suffice.
Fresh Ginger Tea for Stomach Upset
You can usually find fresh ginger as you travel, but just in case I bring a few of these ginger root teabags with me to take when my stomach feels a bit off. They are soothing and as a bonus the warm tea helps calm me just before bed.
Ultimately, when I am sick is when I feel loneliest as a solo traveler, so I am very grateful for technology that lets me chat with friends no matter where I am!
Resources & Inspiration For Food Lovers
I wanted to end this post with some of the books and sites I’ve gone to over and over again to further fuel my love of food. The first is practical, the rest are suggested for the beauty of the scenes they conjure in prose and photos.

There’s nothing more satisfying to me than learning about the stories and history behind the foods on my plate. Here are a few websites that I turn to time and time again as starting points for these culinary explorations:
- Edible Geography
- Food Politics
- Gernot Katzer’s Spice Page
- Politics of the Plate
- The incredible Food Timeline
- History.com’s Hungry History series

I don’t eat salsas from the table at restaurants if they are served in big bowls. There’s just no way they are wasting the leftovers, so I suspect they are reusing the sauces over and over again and even re-canning leftover sauces at the end of the night. It’s just hard for me to imagine Mexicans throwing away big batches of sauces and wasting so much food like they do in the U.S. That being said, if they are served in small portions, I’m more likely to trust. I eat sauces from street vendors if they cover the sauces….at popular food stands those sauces go quick and I doubt they have much left over by the end of the night which is why I trust that better than the restaurant salsas and sauces.
Very useful tips, thank you so much.
These are such good tips for up and coming travelers! Truly wise advice, while still encouraging people to be adventurous with their food. Will definitely take these ideas into consideration when traveling from now on.
Eating street food especially during festivals poses health risks. These tips really are very helpful. When I travel I also stick to eating fruits that you can peel. I did experience some bouts with tummy aches during my travels and drinking warm tea helps calm it down. But of course it is best to still avoid getting sick by eating wisely while traveling.
This is a good topic! Thanks for the tips, some I already know and some I just learned. I also bring antacids and other stomach medicine along with me in case I get an upset stomach from eating street food.
Thanks so much for the useful tips Jodi. I’ve been travelling for some time in Asia already and am now working in Indonesia which is a culinary street feast. I think the tips you’ve suggested are transferable to all countries which is great. I actually never thought about the sauces and I’ve always steered cleared of things with water or fresh fruit that I hadn’t cut or peeled myself. Thanks for the useful info!
These are terrific ideas to try to keep you safer while you are eating like the locals. The food sensitive cards are a good idea.
These were great tips. I’m always dubious with titles that include getting sick and streetfood, largely because a lot of people are pretty snobby about street food. But I loved that you advice was practical and was promoting street food. Especially loved hearing about how you didn’t get sick in India. Street food is such a majour part of cultures and it is something that should be embraced. Thanks for writing this!
I love street foods! They are delicious at the same time cheap.
I got my eating experience living 3 years in Honduras where I learned a lot of hard lessons. Stay away from salads for sure. I got typhoid from a 5 star restaurant that served coleslaw. I noticed while eating that there was dirt in it. I got dysentery from a fried chicken restaurant and terribly sick twice from a small restaurant serving the best enchiladas I ever had that even makes the natives sick as dogs.
Soft drinks are always safe and so are commercially made fruit juices in sealed plastic bags. Coconut water is safe as long as they open the coconuts in front of you.
Like the advice given here, Best to stick with street foods. I learned to look for the crowds and check if the food is covered and still HOT. Eating in the public markets is a good bet. Eat only peeled fruits that you peel yourself. Honduras has terrific oranges and a good variety of fruits, especially on the north coast.
always buy unpeeled fruit that you can peel yourself. The peeled fruit is often cleaned and washed with tap water beforehand and can make you sick
There were so many points that I felt that never crossed my mind. I always thought that it was not to be taken into consideration but when I even read the caption, I was like ‘Yeah! We should do this.’ Just one thing, how to use activated charcoal? I have never used it before, but the way you said, it seems it could be really helpful.
Hi Pooja, thank you for the comment. I took it as noted in the post, usually dosages of 250mg or 500mg depending on severity. It’s important to not take it near any medication or minerals/vitamins, as it will potentially bind to them too and prevent them from being absorbed. It’s not something I take daily.
Thanks for sharing this! Gearing up for travels after the virus gets better, and this has me hungry to eat around the world.
while traveling to any new place we find new things and peaceful ourselves, however but when it comes to the matter of food it’s hard to find the place with good testy hence I find better to go with these type of site to find the good one legal nomads always been a good site to guide the world with different taste…
