Despite continuing technological advancements, preventing products from becoming contaminated with pathogens remains a challenge in the food industry. To monitor foodborne illness, the Foodborne Diseases Active Surveillance Network (FoodNet) actively conducts surveillance of laboratory-diagnosed infections caused by pathogens commonly transmitted through food sources.

FoodNet is a partnership between the Center for Disease Control (CDC), the United States Department of Agriculture’s Food Safety and Inspection Service, 10 state health departments and the Food and Drug Administration (FDA). It monitors infections due to: Campylobacter, Cryptosporidium, Cyclospora, Listeria, Salmonella, STEC, Shigella, Vibrio and Yersinia. To gather the data, outbreaks are monitored at 10 sites throughout the country that account for approximately 15% of the U.S. population. In 2016, FoodNet tracked outbreaks for an estimated 49 million people. The preliminary 2017 FoodNet surveillance data shows that foodborne illness continues to be a considerable health burden despite ongoing food safety measures. Below are three key questions raised by examining the 2017 FoodNet data: Continue Reading

Detection methods for foodborne pathogens and spoilage organisms have come a long way from traditional cultural methods. Advances in technology have led the evolution into rapid detection methods, whether they are antibody-based or nucleic acid-based (i.e., DNA or RNA). These rapid detection methods have been widely adopted by the food industry. However, with so many assays, kits, and methods available, it can be daunting to know where to start when choosing a rapid detection method that fits all your needs and requirements.  While there are many factors to consider, here are five to keep in mind: Continue Reading
