A pilot plant steam treatment system was developed to reduce L. monocytogenes contamination on exterior surfaces of King Salmon (Oncorhynchus tshawytscha) prior to processing. Numbers of surviving L. monocytogenes cells on the surface were determined using an enrichment-based Most Probable Number (MPN) technique. Inoculated L. monocytogenes cells were not recovered from the surface of salmon after exposure to the steam treatment for 8 sec. A 4-log reduction in L. monocytogenes numbers was obtained. Treated salmon could be processed into a high-yielding, high-quality cold smoked product. An in-plant system was subsequently shown to reduce "naturally" occurring L. monocytogenes numbers and produce a high quality final product.
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.
