A Metagenomic Survey of Virological Hazards in Market-Ready Oysters.

Viral contamination of bivalve molluscs, such as oysters, is a well-recognized food safety risk. The aim of this study was to assess virological hazards in market-ready oysters on the Dutch market. Non-targeted metagenome analysis was first performed on norovirus spiked-in samples showing linear and sensitive detection of norovirus GI.

Evaluation of Media and Test Kits for the Detection and Isolation of Escherichia coli O157 from Minced Beef.

This study has evaluated the efficacy of selective enrichment and plating media used for the isolation of verocytotoxin (VT)-producing Escherichia coli (VTEC) of serogroup O157, by examining pure bacterial cultures. In addition, the performance of a variety of commercial test kits for the detection of E. coli O157 strains inoculated into minced beef was compared, using the Ampcor E.
