Coliform bacteria are common contaminants of meats. Why might one expect to find coliforms in samples of meat?

Answer

Coliform bacteria is a Gram negative, rod shaped bacteria which when present in water will indicate that the water may contain disease causing pathogens.

 

Coliform bacteria are present in the digestive tract of animals, humans and also in plant and soil matter. They are also found present in their fecal material of warm blooded animals and humans.

Since it is found present in the intestines of animals it becomes a part of the meat during butchering or slaughtering process. This means during butchering, the digestive tract may be opened and the coliform bacteria will released onto the meat surface and or associated with meat when the meat is contaminated with fecal matter from the animal’s intestine.
