Millions of men, women and children in Mexico have elevated blood lead levels.  Much of the lead poisoning comes from their use of traditional Mexican pottery—the colorful plates, pots and other wares that you see in almost every home and restaurant in the country. Traditional Mexican pottery has been produced by local artisans over the past five centuries using leaded glazes, which were introduced by the Spaniards.

The “Barro Aprobado” project will raise public awareness about the dangers of leaded pottery and promote the use and production of lead-free pottery.  The project launched in Morelos state will expand on its success nationwide.

Barro Aprobado seeks to measure and influence the following indicators: Number of free potters lead-free dining number of lead, blood lead levels in the potters and lead levels in society in general. Pure Earth will follow the first two indicators. While the INSP, with support from the Ministry of Health of Morelos, IMSS and Pure Earth conducted a study to determine the blood lead levels in newborns of Morelos. Lead levels in blood in the pottery community borne by the INSP, the Ministry of Health of Morelos and Pure Earth.

Information collected will be used to generate reports that will be distributed to the general public and concerned authorities to replicate the positive experience of the program in other states.
