Food, Drink and Hygiene
Good personal hygiene, including frequent hand washing is important to help to protect yourself. Safer eating and drinking habits can also make a difference.
Many diseases are caught by consuming contaminated food or drink. These include Traveler's Diarrhea, Hepatitis A and Typhoid Fever.
Travelers diarrhea is the most frequent illness associated with travel to developing countries, affecting 30-80% of travelers in the first two weeks of their trip. "Boil it, cook it, peel it, or forget it" is the golden rule.
Drinking water: boil or sterilise it before use. Use bottled water and check the seal is intact on purchase. Use for drinking, washing food and for cleaning your teeth
Avoid both ICE CUBES and ICE CREAM unless you are sure that they are made from clean water
Avoid food which has been reheated, kept warm or exposed to flies
Avoid uncooked food unless you have prepared it YOURSELF
Shellfish is particularly hazardous
Remember that salads washed in untreated water will be unclean
Avoid un-pasteurized milk or boil it before use
Always wash hands before eating
