I'm not even a little surprised. I stopped heating food in plastic years ago. I have no plastic cups, plates, or utensils. It's not just about the microplastic bits, it's also the chemicals in the plastic that are released by heating. I don't trust that aspect even with the "microwave safe" containers.

Unfortunately, it's impossible to avoid food that has been processed with machines that have plastic parts, or food that is stored in plastic. The only way is to grow your own. Even food that is sold in non-plastic containers was at some point processed by and stored in plastic, before it was packaged for final shipping.

Here's a recent study about microplastic in olive oil. Olive oil sold in glass bottles contained just as much microplastic as that sold in plastic bottles.

All throughout the process, you can see plastic containers, rollers, hoses, gaskets, etc. Every machine used to process food has many plastic parts that wear out, and those bits that wear off the parts end up in our food, it can't be avoided in industrialized food processing:

We're supposed to be picking the fruit off the tree and popping in our mouths, not running it through machines and shipping it back and forth across the world.

Ya no shit

A many years ago we replaced all of our microwave scorched containers with glass snapware and banned plastics from the microwave. Then the microwave died two years ago and we have not bothered to replace it.

Just get some Pyrex. It also doesn't stain just because you had some spaghetti leftovers.

Sadly not surprising. Years ago we switched to glass and never looked back.

What a fucked-up URL.

I feel like this should be obvious, I stopped heating anything in plastic years ago. But, it's very good to get confirmation and wider recognition, of course.

Unfortunately, it's virtually impossible to avoid food that has been processed through plastic machinery, and stored in plastic. You'd literally need to grow your own. Even foods sold in glass or paper containers was processed through industrial machines that include many plastic parts, and stored in-bulk in plastic containers before being packaged in glass for sale.
