Objective To analyze the lead and cadmium contamination of retailed pig viscera in Guangzhou city during 2006to 2011. Methods Samples were collected with stratified random sampling method from supermarkets and farmers'' markets in 12administrative regions of Guangzhou city during 2006to 2011. 235samples included 44lungs, 103livers and 88kidneys. Lead and cadmium contents were determined by graphite furnace atomic absorption spectrometry. Data were analyzed by Chi-square test and Pearson correlation analysis. Results The lead in viscera samples was 0.01-2.45mg/kg, the average content was 0.09mg/kg, the median was 0.06mg/kg and the qualified rate was 99.1%. The cadmium in viscera samples was 0.001-5.232mg/kg, the average content was 0.161mg/kg, the median was 0.036mg/kg and the qualified rate was 97.4%. When the qualified rates were compared, the kidney qualified rate was the lowest(χ²=4.83,P=0.02). The lead qualified rate has no significant difference among years, as for cadmium qualified rate, 2006was the lowest with an increasing trend. Conclusion The cadmium contamination in kidney was relative severe and it suggests to be taken seriously and strengthen the food safety risk monitoring and supervision. \=
