Some of the world’s top scientists are gathering at Penn State next week for an invitation-only workshop to discuss how to reach a consensus on techniques to identify new serotypes of E. coli.

Penn State’s 50-year-old E. coli Reference Center is hosting the international meeting.

“We hope the workshop here

Penn State researchers have found that eggs from small flocks of chickens are more likely to be contaminated with Salmonella enteritidis than eggs sold in grocery stores, which typically come from larger flocks. That conclusion was drawn from a six-month study done last year in Pennsylvania. Researchers from Penn State’s
