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
