These are all foods that are moist or damp, and they have protein that the germs need to grow. Part of your job is to protect the food and to stop germs from growing, so that no one will get sick. First, wash your hands well. Second, be sure that the food is wholesome and protect it from germs. They are everywhere, they grow fast, and they may spoil food or cause food borne illness .
Some bacteria make poisons.
Some poisons are not destroyed by normal cooking. Almost always the food looks and smells good, but it may have enough bacteria or poison to make someone sick. Two examples of this are roast beef that has not been kept cold enough, and chicken soup that has not been kept hot enough. A virus is another kind of germ that causes illness. A virus can be in liquids and foods that a sick person touches.
