Better information. Improved process control.

Enterobacteriaceae are of great importance since these organisms are involved in food spoilage, indicators of fecal contamination in food products, some of which are food borne pathogens. Because the 3M™ Petrifilm™ Enterobacteriaceae Count Plate enumerates all Enterobacteriaceae organisms, it provides a more inclusive picture of potential contamination.
