Barrier films to prevent migration of mineral oils from FCMs
German company develops barrier films to prevent migration of mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH) into food
New study: Chronic diseases caused by chemical exposures in great-grandmothers
Epigenetic mechanisms thought to be responsible for health effects in rat offspring after great-grandmothers were exposed to a chemical mixture during pregnancy
Predicting exposure to food contact chemicals
U.S. EPA scientists develop high-throughput computational models for predicting dietary exposure to chemicals from food packaging; exposure from food contact materials found to contribute significantly to overall exposures
Mineral oils in chocolate Santas
Foodwatch study finds typical Christmas chocolates and sweets to contain mineral oil residues; demands recall of affected products
Ames test insufficient for genotoxicity of FCMs
Scientists deem Ames test unsuitable as standalone method to evaluate genotoxicity of FCM migrates, suggest complementing it with chemical information
Study investigates quantity and risk of oligomers in PBT
Researchers analyze oligomer in extracts and migrates of polybutylene terephthalate (PBT) food contact articles also comparing levels in food and food simulants; report human exposure to oligomers can exceed daily threshold in some scenarios; express the need for toxicological evaluation of PBT oligomers
Indonesia updating national regulation on food contact materials
Indonesia’s draft food contact regulation reorganizes material groups; includes positive and negative substance lists, specific and overall migration limits; testing guidance based on food type, contact time, and temperature; public consultation closed in December 2023, final version expected in 2024
Mapping microplastics in the male reproductive system
Study provides an in-depth look at microplastics in the male reproductive system, analyzes human and mouse samples to chart concentrations and polymer types; finds microplastics in all human testes samples and majority of semen samples; larger plastic particles may get trapped in testis, leading to higher concentrations; identifies correlation between urbanization, home-cooked meals, and body scrub used to microplastics concentration
