Antimicrobial activity of cetylpyridinium chloride washes against pathogenic bacteria on beef surfaces

A Stomacher® 400 was used to help test antimicrobial activity of cetylpyridinium chloride washes against pathogenic bacteria on beef surfaces. The Stomacher® 400 was used to pummel ground beef for 2 minutes as part of the study. The study found that the residue levels of CPC were seen to be too high for human consumption.

The effectiveness of Triclosan-Incorporated plastic against bacteria on beef surfaces

A Stomacher® 400 was used as part of the study to test the effectiveness of Triclosan-Incorporated plastic against bacteria on beef surfaces. The Stomacher® was used to blend sponge samples for 2 minutes. The study demonstrates that while antimicrobial activity is detected against bacterial cultures in antimicrobial plate assays, plastic containing 1500 ppm of triclosan does not effectively reduce bacterial populations on refrigerated, vacuum-packed meat surfaces.
