    The purpose of our research work is to evaluate the levels of lead and cadmium in French fries and, consequently, the toxicological risk to consumers in ten well-known rotisserie chicken restaurants (“pollerías”) in the district of Cercado de Lima. A total of 64 samples, each equivalent to 250 g of French fries, and 370 surveys were collected to assess the toxicological risk. The concentration of metals was determined using the Graphite Furnace Atomic Absorption Spectrophotometry method at CICOTOX. The results showed lead concentrations ranging from a minimum of 0.0040 mg/kg to a maximum of 0.0463 mg/kg, with an average of 0.073 mg/kg. For cadmium, the minimum was 0.03230 mg/kg, the maximum 0.81020 mg/kg, and the average 0.21100 mg/kg. Based on these concentrations, the estimated exposure dose was calculated as DE Pb = 0.0000000052 mg/kg/day and DE Cd = 0.0000000151 mg/kg/day. In conclusion, the concentration of lead (0.0073 mg/kg) in French fries was significantly lower in comparison with cadmium (0.2110 mg/kg), which was significantly higher than the maximum permissible limit established by the CODEX STAN 193-1995 of the WHO/FAO (0.1 mg/kg). According to the toxicological risk assessment methodology of PAHO/WHO, in the district studied there is evidence of a minimal toxicological risk from exposure to the analyzed factors.
