In the present investigation, cadmium concentrations in seafood were determined and compared with the maximum levels of Commission of the European Union in its Regulation (EC) Nº 1881/2006 and amending Regulation (EU) No 488/2014. Samples were collected from the fish market of Villa Maria del Triunfo. Analyses were performed by atomic absorption spectrophotometry. The results were: in fish (horse mackerel: Trachurus picturatus murphyi) the average cadmium concentrations was 0,35 mg/kg fresh weight, well above the allowable value which is 0,05 mg/kg fresh weight. In crustaceans (prawns: Litopenaeus vannamei) the average was 0,42 mg/kg fresh weight, being below the maximum allowed limit which is 0,50 mg/kg fresh weight. The ceiling in bivalve molluscs is 1,00 mg/kg fresh weight and different concentrations were found in different species and in white shells (Semele sp) and scallops (Argopecten purpuratus) do not exceed the permitted limits; the mussels (Aulacomya atra) are borderline; the machas (Mesodesma donacium) and clams (Gari solida) exceed the limit values. Finally, cephalopods (giant squid: Dosidicus gigas) the average was 1,11 mg/kg fresh weight, being slightly higher than the allowable limit 1,00 mg / kg fresh weight.
