Scientists examine associations between exposure factors and levels of per- and polyfluoroalkyl substances (PFASs) in humans; compare several methods of dietary exposure assessment; food contact articles significantly contributed to PFASs intakes
Three studies investigate microplastics in foods; review summarizes particle migration from food packaging into honey and calls for universal analysis methods; research study presents analytical method to detect and identify microplastics in certain foods; survey finds public seems unaware of food packaging as microplastic source and seldomly connects microplastics with human health consequences
Smithers Pira’s annual conference on “Plastics & paper in contact with foodstuffs” covers regulatory updates, summarizes industry initiatives, discusses future developments

In a letter, US Food and Drug Administration (FDA) reminds manufacturers, distributors, and users “that only certain fluorinated polyethylene containers are authorized for food contact use”; reminder necessary following recent findings by US EPA and civil society organizations that some manufacturers are not following FDA regulations
High-pressure processing can change functional structures and migration potential from flexible packaging materials; coated and laminated structures most sensitive; more research needed to find most suitable materials and packaging designs
U.S. EPA submits proposals for significant new use rule for long-chain PFAS, additions to toxics release inventory; Connecticut PFAS task force publishes draft action plan, proposes to evaluate requiring disclosure of PFAS in products; CHEM Trust publishes briefing on PFAS calling for urgent action on the entire family of chemicals
JRC study reviews EU legislation on nanomaterials; summarizes different sectors with nano-specific provisions, such as plastic FCM regulation; more research needed to address regulatory questions
Scientists present life cycle impact assessment method to include human exposure to chemicals in food packaging, discuss trade-offs, interpretation, data needs, consideration of additional toxicity concerns
State of California adopts No Significant Risk Level for styrene of 27 µg/day under Proposition 65; styrene exposure from polystyrene food packaging assumed to be low, likely requiring no warning label
