Total Coliforms Test

Method Description

Enumeration of Total Coliforms on 3M CC Plates involves using pre-prepared Petrifilm plates to enumerate bacteria in a sample. The method targets coliform bacteria, a group that can be indicative for fecal contamination. This convenient and standardized plating system simplifies the process, making it efficient for assessing bacterial levels in various environments, including cannabis, dietary supplements and water.

Additional Information
Coliform testing is used as an indicator of general sanitation. They are generally found in soil and water and are prevalent in raw agricultural commodities like flour. A high coliform count can be indicative of sanitation issues. E. coli is one of many species of coliform and is an indicator of possible fecal contamination. E. coli counts will never be higher than coliform counts. Fecal contamination can never be inferred from coliform results alone. If a product has high coliform counts with no E. coli testing and information concerning possible fecal contamination is desired, the sample will need to be retested for E. coli.
