Sure, if you buy used enamel you can even get uranium. Which looks lovely but I wouldn't cook tomatoes in it.

This is why I specified "buy from a reputable manufacturer" because there is no risk of this whatsoever if you get contemporary / new cookware from the indicated regions; that list isn't exhaustive but I stand by this: any cookware you buy new from EU, America, or Japan, will not contain lead in the glaze, or anything else you wouldn't want to eat very small amounts of.

I heard that even well known brands like Le Creuset pots have lead in the ceramic coating on the outside of the pot. I guess that's not the same as being on the inside. But still, that seems not ideal.
