As the focus on per- and polyfluoroalkyl substances (PFAS) intensifies, multiple states and some U.S. federal agencies are implementing or considering implementation of restrictions or bans on the products use in food contact articles. This article focuses on the restrictions and bans in the U.S. that impact the use of PFAS in food packaging, and includes a discussion of the challenges manufacturers face due to inconsistent science and policy decision related to the use of these chemicals in food packaging.

This article covers U.S. regulatory oversight in establishing pesticide residue tolerances, testing for residues in domestic goods and imports, and the importance of science-based standards for global trade and food safety.

A continuous improvement approach may be useful for poultry operations aiming to reduce the presence of Salmonella in their flocks, in light of the U.S. Department of Agriculture’s initiative that includes increased quantitative microbial monitoring of incoming flocks to processing plants.

A recent study has estimated that removing products with a concentration of Listeria monocytogenes higher than 1 CFU/g could greatly reduce food contamination and associated foodborne illness cases. The study also found ready-to-eat (RTE) foods to be of greatest concern.

Based on Foodborne Diseases Active Surveillance Network (FoodNet) data, a U.S. Centers for Disease Control and Prevention (CDC) report states that the incidence of commonly foodborne enteric infections decreased in the U.S. during 2021.

A recent report by the Food and Agriculture Organization of the United Nations and the World Health Organization raises a concern with the limited existing data on seaweed food safety, and recommends several actions to close knowledge gaps and increase the safety of seaweed consumption.

The U.S. Environmental Protection Agency (EPA) has asked the U.S. Court of Appeals for the Ninth Circuit for a chance to withdraw the agency’s own decision to approve the fungicide difenoconazole for use on crops, agreeing with a lawsuit that states the agency needs to acquire more data on the fungicide’s toxicity.

To understand and eventually reduce the risk of salmonellosis from poultry meat, it is necessary to understand the poultry production system, the introduction of the microorganism into the poultry ecosystem (as well as its gastrointestinal tract), the sources of Salmonella during production, and, subsequently, strategies to control or reduce the risk from this microorganism at both the pre-and post-harvest stages. Part 2 of this article series examines pre-harvest controls during grow-out.

A recent study has demonstrated that seasonality and food type can influence the enteric toxicity and bacterial count of foodborne Staphylococcus aureus.
