“…In addition to the lack of information on lead levels in food, national representative data of blood lead levels in the Mexican population have only recently become available, although they include only children between 1-4 years old, in vulnerable populations (<100,000 inhabitants). The prevalence of blood lead levels ≥5µg/dL (the current blood lead level limit established by the Mexican Health System, and in accordance to the U.S. CDC) was 21.8% and there was a strong association between the use of lead-glazed ceramics and higher blood lead levels [20,21]. Results from epidemiologic studies have shown that overall and across the years, the percentages of Mexican children younger than 5 years old with blood lead concentrations ≥5µg/dL range from 8% -15% and average levels in both children and pregnant women remain nearly 3 times higher than those estimated in the US during the same years [16,22,23].…”
