Diarrhoea To avoid illness, select your meals carefully.
All raw food is subject to contamination.
Eat only food that has been cooked and is still hot, or fruit you've peeled yourself. Undercooked and raw meat, fish, and shellfish may carry various intestinal pathogens. Cooked food that has been allowed to stand lukewarm for several hours may provide a fertile place for bacterial growth - and should be thoroughly reheated before serving. Street food vendors have been associated with increased risk of tummy trouble. Some fish and shellfish can contain poisonous biotoxins, even when well-cooked.
