Enterococcus Faecium is a stomach bacterium that is used as a probiotic in some pet foods.  This bacterium is normally found in the digestive systems of many animals including dogs, cats and humans. Probiotics are generally defined as a living organism, often bacteria, which are used to promote digestive and overall health.

Risks: Enterococcus Faecium is one ‘bad ass’ bacterium. It can live in a multitude of environments and temperatures and is among the leading causes of hospital-acquired infections in the United States and Europe (partly due to its ability to build resistance to anti-biotic drug treatments).
