Resumo
This systematic review (SR) evaluated evidence of lead (Pb) levels in foods consumed or produced in Brazil. Seventy-seven publications were included in this review, corresponding to a total of 8466 food samples that were grouped into 12 food categories with similar characteristics (infant food; sugar; beverages; meat and meat products; nuts, cocoa and products; fruits and fruit products; grains, cereals and products; milk and milk products; eggs; oil and fat spreads; vegetables and vegetable products and other foods). The random model was used to establish levels of Pb in food categories. We used the software R® to perform the meta-analysis. The overall occurrence of Pb was estimated at 0.0541 mg/kg, and ranged from 0.0004 mg/kg to 0.4842 mg/kg. The SR and meta-analysis presented relevant results about Pb contamination on foods, despite the high heterogeneity. They were understood as a viable strategy to answer questions regarding prevalence of Pb which is necessary for the risk assessment of Pb intake in foods.
