Microbiological testing seeks to identify the presence of bacterial pathogens, viruses, and parasites on food contact surfaces, in agricultural water and soil, and in food products. Frequent swabbing to determine if pathogens are present on food processing equipment is an important part of a sound environmental monitoring program (EMP) at a facility.
Funded by the Center for Produce Safety, a University of Georgia researcher is leveraging cutting-edge technology to improve the standard method for detection of viruses on foods, and then will use the method to study infectious norovirus persistence on berries.
As part of the agency’s Leafy Greens STEC Action Plan, the U.S. Food and Drug Administration (FDA) has published a report detailing the results of targeted inspections and microbiological testing of leafy greens grown in Salinas Valley, California during the region’s 2022 harvest season.
With a $5 million grant from the U.S. National Science Foundation (NSF), a multidisciplinary research team is developing sensor-based rapid detection technology, backed by an artificial intelligence (AI) –powered decision support system, to control Salmonella and other foodborne pathogens throughout the poultry supply chain.
Using whole genome sequencing (WGS), U.S. federal and state public health officials recently solved a multistate foodborne illness outbreak investigation that has been ongoing since 2014, with the most recent illnesses being reported in December 2023.
A fully automated assay to detect Cyclospora cayetanensis, developed under a Research Collaboration Agreement between the U.S. Food and Drug Administration (FDA) and Rheonix, is now available to food and environmental testing laboratories, and has been proven to achieve consistent detection rates in samples of high-risk fresh produce with low levels of oocysts.
Two complimentary studies funded by the Center for Produce Safety (CPS) are using genomic sequencing technology to examine how storage conditions affect microbial growth on pears, with a focus on Listeria monocytogenes.
