Virulent bacteriophage for efficient biocontrol of Listeria monocytogenes in ready-to-eat foods.

Stomacher used to prepare hot dogs, sliced turkey meat, smoked salmon, seafood, sliced cabbage, and lettuce leaves for bacteriophage assay against food-borne Listeria monocytogenes. Food-borne Listeria monocytogenes is a serious threat to human health, and new strategies to combat this opportunistic pathogen in foods are needed. Continue reading

Thermal Destruction of Escherichia coli O157:H7 in Sous-Vide Cooked Ground Beef as Affected by Tea Leaf and Apple Skin Powders

Contamination of ground beef with Escherichia coli O157:H7 is a potential health hazard and a continuing concern both for consumers and the food service industry.

The Stomacher® 400 was used to blend beef for 5 five minutes to ensure an even distribution of the organisms in the respective menstruums. Thermal death times from this study will assist the retail food industry to design cooking regimes that ensure the safety of beef contaminated with E. coli O157:H

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.
