Neither does the problem lie with commercially imported pottery. In addition, FDA regulations mandate that imported items not safe for food-use must have a permanent stamp to that effect, usually on the bottom of the piece. The problem centers chiefly around pottery made by artisans or folk-potters in other countries and brought into the U.S. by individuals for their personal use. In some homes, the family cazuela or cooking pot is an heirloom, passed from mother to daughter. Getting the family to abandon it is not always easy, however, that is what must be done because lead is an insidious poison which accumulates in the body.
Lead poisoning affects small children more than adults because of their low body mass.
It can damage young nervous systems and cause physical and mental problems. However, reversing centuries of tradition takes time. Meanwhile, we can still buy, collect and display and use folk-art pottery, but not for food. Home-testing kits for lead compounds can check pottery, paint, soil or other materials for lead compounds but they should not be relied upon exclusively. This kit is available at Home Depot and Builders Square hardware stores and at Target stores.
