Abstract:This preliminary laboratory trial evaluated the potential of hot water shrinkage to reduce post‐lethal surface contamination by Listeria monocytogenes (Lm) in a turkey‐based Virginia ham model. We inoculated triplicate of ham slices (10 cm2, 2‐cm thick) with 105 cfu/cm2 of Lm (ATCC 19114). Subsequently, they were vacuum‐packaged and placed in a thermostated water bath at 75, 80, 85 and 90C for 0, 20, 25 and 30 s. Treatment at 75–85C for up to 30 s did not affect Lm survival, while nearly 4‐log reduction was ob… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
