A publication called HealthDay reports that “a charming ceramic reminder of a Mexican vacation could end up giving you lead poisoning,” according to a new study. Glazes that line traditional Mexican ceramics, cookware, and dishwater often contain high concentrations of lead, which can be toxic when there is repeated exposure. Study lead author Dr. Michael Fralick explains that every time the woman poured hot water into her mug, lead was seeping out of the glaze and into her tea. Fralick is a general internest at the University of Toronto and a research fellow at Harvard. The woman had been hospitalized repeatedly for unexplained but severe abdominal pain as well as anemia, joint pain and extreme fatigue. Tests finally revealed that the glaze on both the inner and outer surfaces of the cookware contained 17 percent lead, and her blood lead concentrations were nearly the 36 times the upper limit of “normal.” She had been using the pottery to cook, boil water, and eat and drink. When she stopped, her lead levels dropped to normal within three months. READ MORE
