This episode covers the final findings from the U.S. Cyclospora outbreak, new USDA efforts to address Listeria, the new FDA Food Code, research on high-pressure processing for raw chicken, and emerging food safety concerns associated with plastic pollution.
In a survey of 48 packaged baby foods from 11 brands, 96 percent contained heavy metals below Consumer Reports’ level of concern. However, alates were detected in most products tested, and microplastics were found in all analyzed purees.
A new FAO technical brief explains how plastic pollution moves through agrifood systems and creates interconnected risks to food safety and human, animal, plant, and environmental health.
This episode of Food Safety Five discusses new research on avocado oil authenticity in processed foods, the effects of nanoplastics on bacterial biofilms in drinking water systems, factors influencing Listeria monocytogenes persistence on plastic food contact surfaces, and stress-adaptation traits that may help E. coli persist from farm to fork.
A new publication from the U.S. Government Accountability Office (GAO) examined the growing presence of microplastics in the environment and the human body, highlighting ongoing scientific uncertainty about their health effects while outlining recent federal efforts to better understand and reduce exposure.
Adding to a growing body of evidence that micro- and nanoplastics may enhance the virulence and persistence of pathogens in food and the environment, a new study found that nanoplastics may strengthen E. coli biofilms in drinking water systems and increase resistance to chlorine treatment.
Moringa oleifera seed extract could potentially serve as a sustainable alternative to conventional alum coagulants for microplastic removal in drinking water treatments, while also allowing for process simplification and cost savings.
EPA has announced its sixth Contaminant Candidate List, which includes PFAS, microplastics, pharmaceuticals, disinfection byproducts, and other chemicals and microbes. Concurrently, HHS unveiled its Systematic Targeting Of MicroPlastics (STOMP)
initiative to address and understand microplastics in the human body.
A literature review conducted by Greenpeace concluded that heating food in plastic packaging—even ready-to-heat meals labeled as “microwave-safe” or “oven-safe”—may significantly increase the migration of microplastics and chemical additives into food.
Researchers found that the presence of nanoplastic particles can increase the expression of virulence and antimicrobial resistance (AMR) genes in Salmonella,and can also encourage biofilm formation.
