Studies suggest food packaging as exposure source to organophosphate esters
Two groups of scientists analyze occurrence and migration of organophosphate esters (OPEs) from hundreds of Chinese plastic and paper food packaging; one study reports higher concentration of OPEs in plastics and migration of 15 out of 23 targeted OPEs; another study identifies presence of 42 and migration of 26 OPEs and identifies seven new compounds

Microplastics: recent insights into human exposure, cellular uptake, cancer metastasis
Researchers report plastic fragments may exacerbate breast cancer metastasis; review summarizes nanoplastic uptake into human cells; studies find occupational microplastics exposure can be reduced by wearing face masks; millions of micro- and nanoplastics are released during 30-second food blending; scientists more worried about microplastic impacts on the environment than humans

Phthalates found in diverse array of foods, from coffee to baby formula
Systematic review summarizes phthalate occurrence in different foods, discusses sources, and potential risk; researchers assess how coffee packaging and brewing method affects bis(2-ethylhexyl)phthalate (DEHP) and di-butyl phthalate (DBP) levels in coffee; perform targeted analysis of 245 plastic additives in baby foods; report widespread contamination including a median of 46.1 ng phthalate esters per gram baby food

Microplastics detected in human testis and semen
Scientists assess microplastics in 30 human semen and 6 testis samples; first to demonstrate presence in human male reproductive system; review finds 9 out of 11 studies demonstrate that plastic particles can translocated across placental barrier

BPS and other color developers migrate from food labels into food
Scientists analyze 140 Canadian samples of food packaging and thermal labels; first to demonstrate that bisphenol S (BPS) and alternative chemicals found in food labels migrate through packaging materials into food; study assesses levels of BPS and other bisphenols in 79 canned Turkish foods; detect BPS in six samples in levels up to 0.036 mg/kg food

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

Microplastics impacts on the reproductive system and offspring
Scientists report human-relevant polystyrene (PS) microplastic concentrations change mice placental metabolism; show nanoplastics have variable effects on placental enzymes using simulations; find pre- and postnatal PS microplastic exposure affects male mice testis development and fertility; recommend future research to analyze multigenerational effects

Micro- and nanoplastics are released from different food contact articles
Researchers report cooking in non-stick Teflon cookware may lead to the release of thousands of micro- and nanoplastics; find 3 to 43 plastic particles prone to be released from Chinese polypropylene takeaway containers; detect around 1,500 microplastics/liter in Iranian bottled water; review points out that micro- and nanoplastic detection methods in food need validation and standardization

Widespread presence of organophosphate esters in plastic and paper FCMs
Scientists perform suspect and non-target analysis of organophosphate esters (OPEs) in 100 food contact materials (FCMs) in Southern China; identify 28 OPEs of which 18 were identified for the first time; find organophosphate antioxidants as one OPE source
