You might not be better off with metal ustensils, loads of PFAS are used in the manufacturing process and end up in the finished product.

A professor once told me: "You cannot avoid contamination, you just have to diversify the sources."

FYI items labeled as microwavable are tested to assess what leaches in the food or liquids under normal use. The leachate has to be identified and approved by the FDA (doesn't mean safe but at least ok-ish)
