What to Know About Food Poisoning When Traveling

Two cases involving possible food poisoning among tourists have raised concerns about what travelers can do to prevent and treat food-borne illnesses — not just during off-the-beaten-path adventures, but in and around resorts.

While the cause of the recent death of Miller Gardner, the 14-year-old son of the former New York Yankees outfielder Brett Gardner, has not been confirmed, Miller, along with other members of the Gardner family, is reported to have experienced gastrointestinal distress after eating a meal while on vacation in Costa Rica. And a lawsuit filed this year in Toronto in connection with the food poisoning-related deaths in 2023 of 8-year-old Stephen Gougeon and his mother, April, alleges, among other things, that the Dominican Republic resort where they stayed did not take sufficient care in food handling.

In general, gastrointestinal illnesses among tourists — travelers’ diarrhea and food poisoning — is especially likely to occur in countries where the water supply is unsafe. But there are also many cases of food poisoning, and hundreds of deaths, in the United States every year, and these infections can occur anywhere there are lapses in how food is handled. Raw or undercooked meat, fish and shellfish can be contaminated, and the Centers for Disease Control and Prevention’s list of high-risk foods includes raw eggs and unpasteurized milk.

Travel presents additional concerns. “People may be in places where the tap water is not necessarily safe, and they don’t have control over how food is prepared or handled,” said Dr. Adam Ratner, director of the division of pediatric infectious diseases at Hassenfeld Children’s Hospital at NYU Langone in New York. “When you’re home, you have some control, and you have U.S. and local health department standards. It can be harder to assess safety somewhere else.”

Parents should be especially vigilant. Babies and young children are vulnerable to dehydration, which is generally the most dangerous aspect of gastrointestinal illnesses; other groups at high risk include pregnant women, older people and anyone who is immunocompromised. But even younger adults and adolescents may not realize how serious the symptoms of food poisoning can be, and when it is important to get medical help.
