目的了解我国食用畜禽内脏的重金属污染和药物残留情况。方法随机抽检全国29个省/市/自治区/兵团市场上销售的772份畜禽内脏样品,并采用国家标准检测方法对重金属污染物(铅、镉、总汞、总砷和铜)和违禁药物(克伦特罗、莱克多巴胺、沙丁胺醇、金刚烷胺和硝基呋喃类)残留情况进行检测分析,同时根据评价标准进行判定。结果 327份猪肝脏样品中,镉、铅、总汞、总砷、铜的超标率分别为2.14%、0.61%、3.98%、1.22%、6.12%,克伦特罗和沙丁胺醇的检出率分别为0.61%和0.31%;84份猪心脏样品中,镉、铅和总汞的超标率分别为3.57%、2.38%和5.95%;88份猪肾脏样品中总汞超标率为11.36%;43份猪肠、32份猪胃中镉超标率分别为2.33%和3.13%。71份鸡肫中镉、总汞和总砷的超标率分别为5.63%、7.04%、21.13%;69份鸡肝脏、31份鸡心脏中总汞超标率分别为11.59%、22.58%;鸭肫的重金属含量与药物残留情况均未发现不合格样品。结论我国畜禽内脏制品重金属污染比例相对较高,存在一定的食品安全风险。
Objective To understand the visceral heavy metal contamination and drug residues of edible livestock and poultry in China. Methods A total of 772 domestic animal offspring samples from 29 provinces / municipalities / autonomous regions / corps in China were randomly selected and tested for heavy metal contaminants (lead, cadmium, total mercury, total arsenic and copper) and illicit drugs (Clenbuterol, ractopamine, salbutamol, amantadine, and nitrofurans) were detected and analyzed, and judged according to the evaluation criteria. Results The over-rates of cadmium, lead, total mercury, total arsenic and copper in 327 samples of swine liver were 2.14%, 0.61%, 3.98%, 1.22% and 6.12% respectively. The detection rates of clenbuterol and salbutamol were 0.61% and 0.31% respectively. The over-standard rate of cadmium, lead and total mercury in 84 pig heart samples were 3.57%, 2.38% and 5.95% respectively. The over-standard total mercury in 88 pig kidney samples was 11.36% and 43 Pig intestine, 32 pig stomach excessive levels of cadmium were 2.33% and 3.13%. The over-standard rates of cadmium, total mercury and total arsenic in 71 chicken portions were 5.63%, 7.04% and 21.13%, respectively. The over-rates of total mercury in 69 pieces of chicken liver and 31 pieces of chicken heart were 11.59% and 22.58% Of the heavy metal content and drug residues were found not qualified samples. Conclusion There is a relatively high proportion of heavy metal pollution in livestock and poultry viscera, which poses some food safety risks.
