摘　　要：目的了解深圳市市售食品中镉污染状况,为采取有针对性的控制措施提供科学依据。方法采取分层随机抽样方法,采集2017年深圳市市售水产品、蔬菜及食用菌、畜肉类等19类2 410份食品样品,用电感耦合等离子体-质谱(ICP-MS)法检测食品中镉含量,检测结果按GB 2762—2017《食品安全国家标准食品中污染物限量》及NY 659—2003《茶叶中铬、镉、汞、砷及氟化物限量》进行评价。结果2 410份样品中镉检出率为48.7%(1 174/2 410),超标率为7.9%(190/2 410)。水产品中镉污染最严重,超标率为24.0%(187/780);其中双壳类镉含量最高,中位数含量为0.340 mg/kg,超标率为34.1%(184/540)。水果超标率为1.3%(1/80),蔬菜及菌类超标率为0.7%(2/270)。不同来源样品超标率差异有统计学意义(P<0.05)。结论深圳市市售水产品、水果、蔬菜及菌类中存在镉含量超标现象,尤其水产品中镉污染严重,建议相关部门采取有效措施,加强监管力度,保障食品安全。Objective To understand the situation of cadmium contamination in foods sold in Shenzhen,and then provide scientific basis for taking pertinent control measures.Methods Totally 2 410 food samples which included aquatic foods,vegetables and fungus,meat and its products,etc.were collected using stratified random sampling in 2017.The contents of cadmium were detected by inductively coupled plasma-mass spectrometry(ICP-MS)and evaluated by the Food Safety National Standards for Pollutant Limits(GB 2762-2017)and the Standards Limites of Cr,Cd,Hg,As and F in Tea(NY 659-2003).Results The detection rate of cadmium was 48.7%(1 174/2 410),and the over limit rate was 7.9%(190/2 410).Among these samples,aquatic foods were the most seriously polluted and the over limit rate reached 24.0%(187/780),and the cadmium content in shellfish was significantly higher than that in other aquatic foods,with the median content of 0.340 mg/kg and the over limit rate of 34.1%(184/540).The descending order of over limit rate was fruit(1.3%,1/80),vegetables and fungus(0.7%,2/270).The differences of the over limit rate from different sources were statistically significant(P<0.05).Conclusion There were cadmium contamination in foods sold in Shenzhen and aquatic foods were the most seriously polluted,which may provide a reference for making polices and taking effective measures for supervision.
