Scientists explore the impact of long-term oral exposure of mammals to food packaging leachates on gut microbiome diversity, composition, and metabolites; report changes in gut microbiota and metabolites mainly associated with oxidative stress, immunity, and inflammatory responses
Peer-reviewed study finds chemicals in plastics induce adipogenesis
Researchers analyze plastic extracts for their chemical composition and promotion of obesity; find one-third induce fat production (adipogenesis); detect several thousand chemicals in the extracts, including known metabolism-disrupting chemicals
US FDA stands by decision on phthalates in food contact
US Food and Drug Administration (FDA) maintains May 2022 decision to deny citizen petition asking the agency to ban eight ortho-phthalates in food contact
Scientists estimate costs of phthalate-associated mortality
Scientific article evaluates mortality in relation to US adult phthalates exposure and quantifies costs; associates phthalate exposure with mortality stemming from all causes, cardiovascular mortality, and a societal cost of $39 to 47 billion per year
PFAS actions in three US states
California expected to pass bill banning PFAS in food packaging; Michigan legislators reintroduce bill to ban PFAS, phthalates, and bisphenols in food packaging; Massachusetts’ Toxics Use Reduction Act program votes for expanding reporting requirements
EFSA final scientific opinion on PFAS in food
European Food Safety Authority (EFSA) publishes final version of its opinion on risk to human health from per- and polyfluoroalkyl substances (PFAS) in food; sets group tolerable weekly intake limit of 4.4 ng/kg body weight for four most commonly measured PFAS in humans
Study finds microplastics impact colon cancer cells, could increase metastasis
Study of colon cancer cell lines finds polystyrene micro and nanoplastic particles (MNPs) can be absorbed into cancerous cells in experimental settings; the more aggressive cell line absorbed the most MNPs and presence of MNPs increased cell movement; evidence of persistence and bioaccumulation; authors argue MNPs fit criteria as substance of concern under REACH
Cyclic oligomer migration is higher from recycled than virgin PET, study finds
Scientists assessed polyethylene terephthalate (PET) trays with different amounts of recycled content and produced by two different extrusion processes; find cyclic oligomer migration increases with recycled content amount, differs between the two processes; nontargeted screening identifies intentional and non-intentional substances, including marker compounds for recycled PET
