The aim of this work was the evaluation of zinc content in piglet’s liver and kidney, which was performed after detection of high concentration of this element in several pig’s feeding stuff in the analysis carried out under the official control, in Portugal. Determinations were executed by flame atomic absorption spectrophotometry (FAAS) after mineralization. Analytical quality control was carried out using control standards. A total of 46 piglets’ offals samples (23 livers and 23 kidneys) from the Aveiro’s district slaughterhouses were analyzed. As expected zinc was detected in all samples analyzed and concentrations were higher in liver than in kidney. The highest values found were 720.73 mg/kg in liver and 472.86 mg/kg in kidney (values considerably higher than usually reported in investigations carried out by different authors).
