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.
The findings suggest that pathogen persistence on plastic food contact surfaces is governed by the combined effects of material composition, engineered surface topography, and microbial ecology rather than any single factor.
Chemical migration and microplastics shedding from recycled plastic food contact materials pose potential food safety concerns. Biopolymer risks are also not yet fully understood. The Codex Alimentarius Commission is considering developing guidance on recycled materials used in food packaging.
A recent study evaluated the migration of non-intentionally added substances from biodegradable food contact materials (FCMs) under different conditions. The researchers underlined the importance of optimizing polymer blends and processing, and considering chemical analysis in FCM risk assessment.
The Packaging and Packaging Waste Regulation (PPWR) limits PFAS in food packaging, bans single-use plastics for fruit and vegetables under a certain weight, and sets forth other changes, with compliance deadlines beginning as early as August 2026.
Following the EU ban on BPA in food contact materials (FCMs), which specified FCM manufacturing applications where other “hazardous” bisphenols may be used, EFSA issued a draft statement on related safety data requirements.
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.
Glove manufacturer Eagle Protect PBC has submitted a petition to FDA urging the agency to prohibit the use of polyvinyl chloride (PVC or vinyl) disposable gloves for food handling in the U.S., citing compliance gaps, poor durability, and chemical risks.
A review published by EFSA concludes that, while there is clear evidence of microplastic release from food contact materials (FCMs), the actual quantities are likely lower than many studies suggest, and current evidence does not support reliable exposure estimates. Nanoplastics data remain insufficient.
