A recent study conducted by researchers from the University of Illinois Urbana-Champaign concluded that, when sampling powdered infant formula for Cronobacter contamination, sampling with stratification may be more powerful than random sampling, and that taking more samples, even if smaller, increases the ability to detect contamination.

PathogenDx’s new rapid single test detects 13 Salmonella serotypes in poultry that are a significant contributor to foodborne illness.

Spectacular Labs Inc. will unveil its plans for a fast, accurate, and automated pathogen testing platform at the upcoming International Association for Food Protection (IAFP) 2023 Annual Meeting, taking place July 16–19 in Toronto, Ontario, Canada at the Metro Toronto Convention Center.

Salmonella infection is one of the most commonly reported causes of foodborne illness, resulting in over 80 million cases of foodborne salmonellosis each year globally.

A recent study has demonstrated the benefits of interagency collaboration during foodborne illness outbreak investigations. The study was conducted by researchers from the U.S. Food and Drug Administration’s Center for Food Safety and Applied Nutrition (FDA’s CFSAN) and the U.S. Centers for Disease Control and Prevention (CDC). 

Some will argue that more sensitive methods are needed to drive change. This is a reasonable argument, but it misses the underlying problem of defining the mission before implementing a sampling and testing program.

Researchers from the Singapore Food Agency’s National Center for Food Science and the National University of Singapore have developed a real-time polymerase chain reaction (PCR) approach for the detection of viable Salmonella Enteritidis contamination in shell eggs, which would accelerate the traditional Salmonella testing process if integrated.

Researchers from Pusan National University in Busan, South Korea have developed a polydiacetylene-based sensor that offers rapid visual detection of biogenic amines released from spoiled food, indicating when products have gone bad.

The Association of Official Agricultural Chemists Africa Section (AOAC Africa) has established a partnership with the African Organization for Standardization (ARSO) to develop analytical methods for the continent’s most widely consumed foods. 

In this episode of Food Safety Matters, we talk with Martin Wiedmann, Ph.D., D.V.M., the Gellert Family Professor in Food Safety and Food Science at Cornell University, about his research on Listeria and Salmonella, his work to strengthen foodborne illness surveillance and response, his use of whole genome sequencing (WGS), and other topics.
