Four studies investigate bisphenol (BP) migration from food packaging and human health effects; demonstrate wide presence of 11 bisphenols in polystyrene take-out food containers from China, Canada, and Poland; report material quality influences BPA migration from polycarbonate cups; indicate higher BPA migration from lined cans than plastic packaging into meat based on probabilistic models; find bisphenols A, F, and S induce genotoxic effects and changes in human endogenous retroviruses (HERVs) expression using human blood cells
Studies detect microplastics in food and link it to packaging, processing equipment
Several articles published since the beginning of 2023 have analyzed plastic particles in packaged foods and beverages, including salt, sugar, canned fish, bottled water, soft drinks, and cold tea; draw a connection to packaging and food processing; migration studies demonstrate particle release from plastic food containers and breastmilk storage bags; review develops 10 criteria for data quality assessment and find most studies “unreliable” on one or more criteria
Webinar on drivers for change in FCMs
Chemical Watch webinar to discuss challenges, trends, and opportunities in food contact materials (FCMs); include presentations from Nestlé and HAVI
Nestlé and Havi: Drivers for change in FCMs and packaging
EDC criteria: Latest revision and next meeting
EU Commission publishes latest version of revised criteria to identify endocrine disruptors; NGOs and industry still dissatisfied with proposed criteria; next expert meeting, and possible vote, to be held February 28, 2017
Researches develop and evaluate methods for food contact chemical determination
Propose method to analyze chemical markers of mineral oil aromatic hydrocarbons (MOAH) from printing inks in food packaging; present workflow that includes in silico prediction tools to identify nonvolatile migrates from food packaging; evaluate efficiency and reliability of methodology for non-target identification of volatile substances
Plastic recycling: company commitments and chemical safety challenges
Scientists report most large companies commit to reducing plastic pollution but focus on recycling; extrusion of recycled materials and legacy compounds in recycled materials as safety challenge; some substances increase others decrease with the increase in recycled content in polyethylene terephthalate (PET) bottles; tentatively identify 212 volatile chemicals in 57 different recycled PET flakes available in China; present migration model to characterize the exposure and risk of PET oligomers
New research on chemical migration from plastic, paper, can coating, and reusables
Recent reports investigate whitening agents’ migration from disposable plastic containers; characterize 153 chemicals migrating from paper packaging and show estimated dietary exposure for children to per- and polyfluorinated alkyl substances (PFAS) exceed safety threshold; detect brominated flame retardants in repeat-use food contact articles; review metal can coating literature concerning coatings types, chemical migrants, detection methods, dietary exposure, and regulatory
Studies investigate circular economy barriers, consumer perceptions
Recent set of articles in peer-reviewed scientific journals review current barriers in flexible plastics to achieving circular economy, recommends regulatory policies be tailored to individual steps in supply chain; consumers easily confused by plastic waste management system, recycling processes, biodegradability claims; researchers instead propose food system shift towards decentralization, shorter supply chains
Measuring plastic particles released from food packaging and in human lungs
Scientists investigate plastic particles released from store-bought food packaging as well as human and mice health impacts of exposure; report single-use plastic products release >1012 nano-sized particles during use; find microplastics to suppress lysosomal activity in mouse macrophages; first detection of microplastics within human lung tissue samples; in vitro neurotoxicity study finds microplastics negatively impact human forebrain organoid development
