If a crockpot has a crackled look on the inside, does it risk exposing you to lead from the stoneware?

Obviously, lead glaze in many crockpots leach into food...but all clay contains lead and I'm wondering if the crackled inside of the pot, where the glazed finish is, means that there are tiny cracks and therefore lead can be leaching into the food? It is a Farberware crock, a year old, and Farberware (along with Rival and many others admit to lead being in their products, along with dishes and silverware).
