Abstract
From 1993 to 1997, UC nutrition, family and consumer sciences advisors in 21 counties tested nearly 6,000 items of ceramic ware, of which 14.2% leached lead. More than half of the items manufactured in Mexico (51.9%) tested positive for leached lead with the UC Quick Lead Test. Ceramic ware from other countries, including the United States, also tested positive. No factors, other than being made in Mexico, were found to be useful predictors for lead leaching on any individual piece of ceramic ware. Consumers concerned about the possible leaching of lead from their ceramic ware should test each item individually.
