3M Food Safety (Microbiology) offers the Petrifilm Enterobacteriaceae (EB) count plates designed to provide a broader indication of food contamination than coliform tests.
3M Petrifilm Enterobacteriaceae count plates allow easy differentiation between EB and non-EB organisms with the combination of acid zones, red colour and presence of gas easily identifying a colony as an EB. The VRBGA method does not use gas or acid as indicators.
Offering 24-hour result for both positives and negatives, the Petrifilm Enterobacteriaceae count plates eliminate the need for result confirmation whereas the VRBGA method requires confirmation, taking at least another 24 hours.
3M Petrifilm Enterobacteriaceae count plates can identify all coliform organisms in addition to potentially pathogenic non-coliform Enterobacteriaceae such as Salmonella, Shigella and Yersinia.
