Cooking food kills germs. All meats, fish, and poultry should be well cooked. Nothing should look raw or have a raw color.
If the food begins to cool, the germs quickly start to grow again. If the food is not eaten within 2 hours, reheat it until it is very hot. Liquids should be bubbling, and solids (like rice) should be steaming.
Some communities have traditional ways to prepare raw meat or fish that make them safe to eat.
