Recent Studies from University of California Davis Add New Data to Escherichia coli (Evaluation of Environmental Risk Factors Associated With Survival of Generic e. Coli In Organic Integrated Crop-livestock Systems In California and...).

Recent studies from the University of California Davis focused on evaluating environmental risk factors associated with the survival of generic Escherichia coli in organic integrated crop-livestock systems in California and Minnesota. The research found that soil contamination by non-O157 STEC increased in 2022 compared to 2021, with concentrations of gEc in grazed soil returning to levels comparable to non-grazed or fallow treatments within 87-147 days post-graze. The study concluded that further investigation is needed to evaluate the adoption of specific rules between manure application by grazing and harvest to mitigate pathogen loads.
