David Tomas & Dr. Vikrant Dutta: STEC Detection in Beef | Ep. 122
In this episode of The Beef Podcast Show, David Tomas and Dr. Vikrant Dutta from bioMérieux explore how regulation, science, and industry challenges intersect in modern beef safety management. From regulation to industry challenges, they explain what PEC, STEC, and E.coli O157:H7 mean for the beef sector—and why it matters. Explore the future of export/import regulations, evolving risks, and the impact of diagnostics to rapidly identify samples containing Shiga Toxin-producing Escherichia coli (STEC). Listen now on all major platforms!
"PEC markers are associated with specific strains and provide a true positive only when the markers are present in the same cell, helping reduce the number of positives in the preliminary screening." - David Tomas
