    This study determined the concentrations of cadmium, lead, and mercury in shrimp (Litopenaeus vannamei) sold at the fishing terminals of Villa María del Triunfo in Lima and Ventanilla in Callao during March–April 2016. The technique used for the determination of lead and cadmium was atomic absorption spectrophotometry with a graphite furnace, and a hydride generator was used for mercury. For this work, 20 shrimp units were collected. For lead, an average value of 0.50 mg/kg was found, with extreme values between 0.28 mg/kg and 0.79 mg/kg. 50% of the samples exceeded the permissible limits (LMP) according to the National Fisheries Health Service (SANIPES). For cadmium, the average value was 0.42 mg/kg, with extreme values between 0.24 mg/kg and 0.65 mg/kg. 35% exceeded the permissible limits (LMP) according to SANIPES. For mercury, the average value was 0.19 mg/kg, with extreme values between 0.07 mg/kg and 0.34 mg/kg. This last value did not exceed the maximum permissible limits (LMP) established by SANIPES. The highest metal concentration found in shrimp (Litopenaeus vannamei) corresponds to lead.
