The Neogen (formally 3M) Petrifilm E.coli/Coliform Count plates yield a count for E.coli and Total Coliforms, with confirmed results available in 24-48 hours.
Benefits
- Confirmed results in 24-48 hours
- Two counts using the one plate and incubation time
- Can be used with the 3M Petrifilm Plate Reader for consistent, fast, automated reading and recording results
- Has been awarded official methods of analysis OMA #991.14 for food OMA #998.08 for poultry, meat and seafood
Please Note: An incubator is required to run this test
To confirm E.coli, look for blue to red/blue colonies associated with entrapped gas, regardless of their size or colour intensity. Other Coliform colonies are red and closely associated with entrapped gas within one colony diameter. Colonies without gas (i.e., a distance greater than one colony diameter between colony and gas bubble) are not considered as coliforms.The Total coliform count includes both red and blue colonies associated with gas at 24 hours. Any blue colony associated with gas that appears within the validated method incubation period is confirmed as E.coli.
