Plastic pervasive in food supply, says new study:
Micro and nanoplastics are pervasive in our food supply and may be affecting food safety and security on a global scale, a new study led by CSIRO, Australia's national science agency, has found.
The study is one of the first to analyze the academic literature on microplastics from a food safety and food security risk viewpoint, building on past studies which primarily tracked plastics in fish.
It shows that plastics and their additives are present at a range of concentrations not only in fish but in many products including meat, chicken, rice, water, take-away food and drink, and even fresh produce.
CSIRO analytical chemist, food safety specialist and lead author of the paper, Dr. Jordi Nelis, said these plastics enter the human food chain through numerous pathways, such as ingestion as shown in the fish studies, but one of the main ways is through food processing and packaging. The research is published in the journal TrAC Trends in Analytical Chemistry.
[...] There are currently no definitive studies that demonstrate micro and nanoplastics in the environment cause harm to humans, however more research is needed to fully understand health effects.
[...] "The key missing information is determining safe levels of microplastics. We currently don't know exactly what the microplastic flux through the food system is or which levels can be considered safe," Dr. Nelis said.

I have a cast iron skillet I inherited from my parents. The "YOU ATE IT DUMMY" thing actually works in your favor with cast iron. You eat iron. Your body needs iron. There are some rare conditions where you can get too much iron, and shouldn't use one; but if you're one of those people I think you bioaccumulate iron no matter what.
Yes, it's harder to avoid some sticky things. So what? It's part of the seasoning process, and if you get junk that's not part of the seasoning you scour it a bit (but not too much) or scrape it off with a spoon.
Oh, but that's work. There's a reason sloth is one of the deadly sins. Enjoy whatever the PFOAs do to you because you're too lazy to scrape a pan.
