Popcorn contains lead?

Popcorn itself does not contain lead, and do not need to add lead, popcorn pots generally do not contain lead,

But the old-fashioned popcorn pots (that is, when you open the pot like a cannon like a loud noise of the kind, now rare), the pot sealing with molten lead seams, at high temperatures there will be a large amount of lead into the popcorn.

Now do popcorn, most of the pressure cooker, with speed popping corn, with a small liquefied petroleum gas stove heating, often seen on the street. This practice is lead-free. However, it should be noted that the operator used to stir with usually a wire, containing lead, zinc and other substances. Rarely is a stainless steel wire used.
