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:
