Pad thai from a Bangkok road vendor or uncooked milk cheese from a bistro in France style scrumptious within the second. However for a lot of vacationers, the native dishes that make journeys significant typically give them meals poisoning—and the flawed type of trip recollections.
By some metrics, gastrointestinal infections associated to meals or water have an effect on 30 to 70 percent of all vacationers throughout or instantly after their journeys, in accordance with a 2015 research in BMJ Medical Proof. Each year, one in six Individuals and almost one in 10 individuals worldwide endure from such diseases brought on by micro organism (E. coli, salmonella, listeria), viruses (norovirus, hepatitis A), or parasites (giardiasis, roundworms, tapeworms).
Decrease-income nations have a repute for placing vacationers at the next threat for meals poisoning, however persons are simply as more likely to be sickened from an improperly dealt with meal in Italy or Australia—or from some sushi at their native grocery store.
Right here’s why individuals get meals poisoning, what to do if it strikes, and the right way to (perhaps) forestall it.
What causes meals poisoning?
There are 31 major known pathogens that trigger foodborne diseases, together with norovirus, salmonella, E. coli, clostridium perfringens, and campylobacter. Relying on the micro organism, parasite, or virus, signs may embrace just a few hours to every week of diarrhea and vomiting, plus abdomen cramps, fever, or physique aches. The almost definitely culprits? Uncooked or undercooked rooster, turkey, or meat; uncooked milk; uncooked vegetables and fruit; shellfish; and meals saved in unsafe temperatures (e.g. an open-air buffet) or ready in an unsanitary means.

Or the water is perhaps making you sick. Based on the U.S. Centers for Disease Control (CDC), more than 180 countries (including popular destinations the Maldives, Mexico, and the Bahamas), have faucet water that’s unsafe to drink. Which means brushing your tooth with native faucet water and even washing your fingers earlier than making ready lunch may result in sickness.
“Giardia parasite is fairly widespread with contaminated water,” says Cindy Chung, a physician at Kaiser San Rafael Pediatrics in California. “When a child comes into my workplace with sudden diarrhea, I ask, ‘Have you ever been tenting? Did you go to the seashore? Have you ever traveled?’”
What can I do if I get sick?
There’s no fast repair for foodborne diseases. Most will resolve as soon as the micro organism or toxins have been flushed out by way of watery diarrhea or vomiting. To fight the discomfort throughout this disagreeable interval, medical doctors advocate ample fluids to stop dehydration and over-the-counter painkillers (ibuprofen, naproxen) for abdomen cramps.
Since diarrhea and vomiting are your physique’s pure immune response to expel toxins, solely take anti-diarrhea and anti-nausea drugs resembling loperamide (Imodium A-D) and bismuth subsalicylate (Pepto-Bismol) for those who’re boarding a bus or airplane and gained’t have simple lavatory entry.
(Should you really buy travel insurance?)
To remain hydrated, Chung recommends Pedialyte or low-sugar Gatorade. “An excessive amount of sugar makes you’re feeling worse when you could have vomiting and diarrhea,” she says. For extreme instances, particularly for youngsters or the aged, contemplate having a physician prescribe ondansetron (Zofran), a medication that slows down vomiting so you’ll be able to drink extra fluids.
You could possibly cancel or reschedule journey for those who’re too in poor health to maneuver. Journey insurance coverage typically considers meals poisoning a sound purpose to make flight adjustments. “However you’ll be able to’t go to the physician the day after your missed flight and get a retroactive analysis,” says Michelle Sofa-Friedman, an ombudsman columnist for The Factors Man and founding father of Consumer Rescue, a client advocacy group.
What to do earlier than a visit
Anxious about getting sick on a visit? Seek the advice of your basic practitioner or a journey clinic for suggestions on drugs or vaccinations primarily based in your vacation spot. “We would offer you a three-day course of azithromycin (Zithromax) as a result of, with touring, one of the crucial widespread micro organism is E. coli,” says Chung. “However we inform sufferers to not use it until their stools have blood.” A health care provider might offer you a hepatitis A vaccine to stop sickness from contaminated meals or water.
To assist beat back diarrhea, consultants at Mount Sinai recommend taking two Pepto-Bismol tablets, 4 instances a day, earlier than and through your journey. This advice is based on a landmark 1987 study of scholars touring to Mexico, which confirmed that Pepto’s lively ingredient, bismuth subsalicylate, lowered the incidence of traveler’s diarrhea by roughly 60 %.
“Typically, E. coli is the commonest trigger for traveler’s diarrhea, and the medicine might assist forestall the micro organism from taking maintain and [you] creating any signs,” says Michael Bolaris, chair of pediatrics and chief of infectious disease at Rancho Los Amigos National Rehabilitation Center in Downey, California. Bolaris cautions that taking bismuth subsalicylate might temporarily give travelers harmless black stools or tongues.
Pack electrolyte powders, water purification tablets, filtered water bottles, and hand sanitizer in addition to anti-diarrhea, anti-nausea, and anti inflammatory drugs. Keep supplies in your carry-on, in case of mid-flight sickness or lost luggage.
Remember that the water in airplane bathrooms isn’t potable. “You may actually be introducing yucky microbes by washing your hands prior to a meal or brushing your teeth,” says Couch-Friedman. “Bring a bottle of spring water into the bathroom to brush your teeth, and use hand sanitizer. Otherwise, you could fast-track yourself to gastrointestinal problems.”
What to do during a trip
Find out if the tap water is safe to drink in your destination with the CDC’s Traveler’s Health tool. Many inns in locations with unsafe water have their very own filtration programs or present bottled water. However nasties might come from that iced water at a road market or berries at a roadside meals stand. When unsure, keep away from ice, and drink bottled water.
Involved about single-use plastics? Deliver a heavy-duty filtered water bottle (resembling Grayl) and fill it with boiled water (if the resort has a kettle) or water handled with purification tablets (Globaline, Potable-Aqua).
Generally, meals poisoning occurs as a result of vacationers have by no means encountered widespread micro organism and viruses at their vacation spot. “Locals construct up some degree of tolerance as a result of their immune programs have been uncovered a number of instances,” says Bolaris.

That doesn’t imply it’s important to forgo road meals in Southeast Asia or taco stands in Mexico Metropolis. Bolaris’ rule? For those who can’t clear it or peel it, don’t eat it. Chung advises vacationers to observe how distributors prep meals. “Are they utilizing utensils, gloves, or naked fingers?” When unsure, persist with piping sizzling dishes—grilled meats or fried fritters—and shun uncooked seafood and lukewarm stews.
Assist is perhaps coming
Just a few firms are creating a vaccine in opposition to norovirus, which infects 700 million individuals a 12 months worldwide. The U.S. Meals and Drug Administration is launching new Food Traceability Rules in 2026, designed to cut back foodborne sickness and deaths by making it simpler to hint contaminated meals—cheeses, fruits, greens, and seafood—all through the availability chain.
