The 3M Petrifilm Salmonella Express System provides qualitative detection and biochemical confirmation of Salmonella in enriched food and food process environmental samples. It eliminates time-consuming agar methods and gives you biochemical confirmation in as little as 44 hours—2X faster than traditional agar methods—with no special equipment.

The easy-to-use system consists of:

  • 3M Salmonella Enrichment Base and 3M Salmonella Enrichment Supplement—a unique medium for recovery and growth of Salmonella species.
  • 3M Petrifilm Salmonella Express Plate—a sample-ready, chromogenic culture medium that is selective and differential for Salmonella and provides a presumptive result.
  • 3M Petrifilm Salmonella Express Confirmation Disk—contains a biochemical substrate that facilitates the biochemical confirmation of Salmonella species.


In-house biochemical confirmation:
The 3M Petrifilm Salmonella Express System saves you time and money by allowing you to confirm multiple presumptive positive colonies at the same time, right in your lab. One disk can biochemically confirm all presumptive positive colonies on the plate with one test. And, there’s no need to pick and transfer colonies to any other agar plates for testing with another technology or send them out to a reference lab for biochemical confirmation.

Using 3M Petrifilm Plate technology, 3M has created a pathogen solution for food testers around the world. 3M Petrifilm Plates are the #1 brand in food indicator testing. Ninety out of 100 of the Top Food Processing Companies in the U.S. use 3M Petrifilm Plates for their testing. Why?

Because these easy-to-use plates eliminate the need to prepare, purchase and store agar dishes, helping to maximize laboratory productivity and efficiency, while delivering consistent, accurate results.
