Risks From Food

To avoid illness, travellers should be advised to select food with care. All raw food is subject to contamination. Particularly in areas where hygiene and sanitation are inadequate, the traveller should be advised to avoid salads, uncooked vegetables, and unpasteurized milk and milk products such as cheese, and to eat only food that has been cooked and is still hot or fruit that has been washed in clean water and then peeled by the traveller personally. Undercooked and raw meat, fish, and shellfish can carry various intestinal pathogens. Cooked food that has been allowed to stand for several hours at ambient temperature can provide a fertile medium for bacterial growth and should be thoroughly reheated before serving. Consumption of food and beverages obtained from street vendors has been associated with an increased risk of illness.

The easiest way to guarantee a safe food source for an infant <6 months of age is to have the infant breastfeed. If the infant has already been weaned from the breast, formula prepared from commercial powder and boiled water is the safest and most practical food.

Cholera cases have occurred in people who ate crab brought back from Latin America by travellers. Travellers should be advised not to bring perishable seafood with them when they return to the United States from high-risk areas. Moreover, travellers may assume incorrectly that food and water aboard commercial aircraft are safe. Food and water may be obtained in the country of departure, where items may be contaminated.
