According to a survey by CDC researchers, nine percent of consumers reported eating prepackaged frozen vegetables raw and 40 percent reported not following cooking instructions, underlining the importance of preventive controls and processing steps to reduce pathogen contamination during production.

This episode of Food Safety Five discusses two recent scientific studies that are advancing the food industry’s understanding of and ability to address Listeria monocytogenes, including new findings about the pathogen’s behavior in biofilms and a developing rapid detection method.

A Boston University study has shown that Escherichia coli exposed to microplastics form strong biofilms and develop increased levels of antimicrobial resistance (AMR) and multi-drug resistance. 

A new study by USDA researchers has shown that long-read whole genome sequencing (WGS) could detect Salmonella attachment to food-contact surfaces earlier than traditional culture-based methods, allowing for sanitation interventions to be applied before the maturation of robust and difficult-to-remove biofilms.

According to a pre-publication version of a study conducted by Cornell University and backed by FDA, aging raw milk cheese may not be effective at eliminating the Highly Pathogenic Avian Influenza H5N1 virus. However, adequate heat treating or pH 5.0 conditions could be effective.

In a March 10 meeting with the CEOs of food industry giants, HHS Secretary Robert F. Kennedy Jr. (RFK Jr), known for his “Make America Healthy Again” agenda, demanded that their companies end the use of artificial food dyes in their products—before the government is forced to act.

HHS Secretary Robert F. Kennedy Jr. (RFK Jr.) has directed FDA to explore ways to eliminate the “Generally Recognized as Safe” (GRAS) rule, which is considered by critics to be a “loophole” that enables ingredients to enter the food supply without oversight or a formal safety review.

Two key advisory committees, responsible for providing impartial scientific advice to federal public health agencies (USDA, FDA, CDC) relative to food safety, have been terminated: the National Advisory Committee on Microbiological Criteria for Foods (NACMCF) and National Advisory Committee on Meat and Poultry Inspection (NACMPI).

Following mass layoffs that swept regulatory agencies, including those responsible for food safety and foodborne illness response, the U.S. Office of Personnel Management (OPM) has walked back its orders to dismiss probationary employees. The change was prompted by a court decision that deemed OPM’s orders to dismiss staffers as unlawful.

Arizona House Bill 2164, aiming to ban 11 chemicals and colorants, has passed the state House and has moved onto the Senate. Similar bills are currently progressing in West Virginia and Texas.
