I don't know, it killing lots of things with lungs seems like a red flag to me.

Perhaps it warrants switching the assumption "Teflon good (until proved harmful)" to "Teflon bad (until proven safe)".

I'd be open to that viewpoint. Assuming something to be bad based on an animal trial is generally how we approve medicines, so there's precedent for it.

I will say that we should be wary of banning products based on potential long-term effects with unknown magnitude. Knowing where to draw that line is tough.

It's already proven not to be safe. If you overheat a pan and breath it in you'll come down with flu like symptoms and nausea.
