Despite increased regulatory efforts, Salmonella outbreaks linked to chicken remain a significant public health threat in the U.S., reaffirms a new study by CDC and USDA-FSIS researchers. The majority of outbreaks involved chicken parts and five serotypes of concern.

During an October 29 Senate confirmation hearing, Dr. Mindy Brashears, the presidential nominee for USDA Under Secretary for Food Safety, has provided insight into what her priorities will be if she is confirmed for the position—with Salmonella topping her list, followed by Listeria.

An analysis conducted by Cornell University researchers sought to better understand the genomic characteristics associated with an important reoccurring, emerging, and persistent (REP) Salmonella strain, S. Infantis REPJFX01, to help inform targeted interventions.

A recent study sought to better understand the ability of Listeria monocytogenes biofilms on stainless steel surfaces to withstand common industry sanitizers, chlorine and PAA, using strains and temperature conditions relevant to the fresh leafy greens supply chain. 

Food industry representatives and consumer advocacy groups have shared their comments, which are varied in opinion, submitted in response to FDA and USDA’s joint request for information to support a federal definition for ultra-processed foods (UPFs).

Americans for Ingredient Transparency (AFIT) is campaigning for federal action to “correct a maze of state-by-state-laws” that restrict or prohibit the use of colorants, additives, and ingredients in foods. AFIT is backed by many of the largest food industry associations and companies, some of which have made voluntary commitments to phase out food dyes or other additives.

This episode of Food Safety Five discusses a UK proposed ban on Bisphenol A (BPA) in food contact materials, as well as two studies with global relevance: a successful clinical trial for a novel Salmonella vaccine and research demonstrating how nanoplastics enter the edible parts of crops.

A recent study investigating biofilms in water hoses used in a meat processing facility revealed widespread microbial colonization, reaffirming concerns about hoses as reservoirs for pathogens, and underscoring the need for routine monitoring and maintenance of water delivery systems.

Among the approximately 1,300 CDC staffers that were laid off by President Trump amid the government shutdown reductions in force (RIFs), 700 were quickly rehired, including the entire staff and editors of CDC’s Morbidity and Mortality Weekly Report, and 70 Epidemic Intelligence Service officers.

The International Association of Color Manufacturers has filed a lawsuit against the recently enacted West Virginia House Bill 2354, which prohibits foods containing certain artificial colorants and additives from being sold in the state, arguing that it is unconstitutional and unlawful.
