Bacteria in meat

Although most bacteria are harmless to humans, some of them are diseases=causing. Pathogens are bacteria that can cause illnesses. Food-borne illnesses occur when pathogens enter our food. Bacteria can be found in any kind of food but they  have a tendency to flourish in of protein rich foods like meat, poultry, eggs and dairy products.. The food that we purchase is usually already contaminated by bacteria, but this problem is easily solved by properly cooking our food.

Irradiation is another method of removing bacteria from our food, especially from meat products. This is done by bombarding the meat with either an electron beam or by gamma ray radiation. Irradiated food is thought to be safe to eat but there might be some changes in its taste, although many food activists disagree with this.
