Plenty of plastics are in contact with food. Including polyethylene which is endocrine disruptive and used in milk cartons, soft packaging for berries and more.
Here is an example. USA is one of the countries mentioned in this study.
“…In addition, the compounds in a frozen blueberry package (LDPE 3) and a yogurt cup lid (PP 5a) activated the ERα > 20%, and another 11 samples induced weak estrogenic effects (>LOD and <20%)…”
“…We also detected significant antiandrogenicity in 14 samples (Figure 1D). Several LDPE, PVC, and PUR products contained chemicals inducing potent antagonistic effects at the AR, while the compounds extracted from PET and PP articles did not contain antiandrogens. At the highest tested concentration, exposure to four of the antiandrogenic samples (LDPE 2 and 5, PVC 1 and 4) resulted in 8–16% fewer cells than in the controls…”
“Antiandrogenic effects meaning”, google result:
“A substance that keeps androgens (male sex hormones) from binding to proteins called androgen receptors, which are found in normal prostate cells, some prostate cancer cells, and in cells of some other tissues. Preventing this binding blocks the effects of these hormones in the body.”
Continuing from the study link:
“…The chemicals in LDPE and PVC induced a significantly stronger PPARγ activity than the ones in PET and PP and the estrogenic activity is significantly stronger in PS than for products made of HDPE, PET, and PVC…”
“…Impact of the polymer type on receptor activity at (A) PPARγ…” see .Figure 4 in the study.
“…The active compound clustering with the antiandrogenic activity, 1-dodecyl-2-pyrrolidinone (CAS 2687-96-9), is a surface-active agent and was detected in all three LDPE freezer bags and the frozen blueberry packaging (LDPE 7)…”
