目的了解漯河市畜产品中铅、镉、总汞的污染状况,为食品安全风险评估提供依据。方法采集漯河市肉、肝肾、蛋、乳4类畜产品共102份样品,对重金属铅、镉、总汞进行检测。结果 4年中监测的102份样品中重金属污染物铅、镉、总汞的总体检出率为61.8%,总体超标率为1.6%,连续4年总体检出率差异有统计学意义(χ2=6.88,P<0.05),总体超标率差异有统计学意义(χ2=9.44,P<0.05)。铅、镉、总汞3种重金属污染物中以铅的超标率和检出率为最高,分别达到了48.0%和3.9%,铅、镉、总汞的检出率差异无统计学意义(χ2=11.59,P>0.05),超标率差异无统计学意义(χ2=5.21,P>0.05)。不同种类畜产品中肝肾类食品污染物检出率为最高,达到了100.0%,超标率最高的为肉类食品,超标率为2.9%,检出率差异无统计学意义(χ2=9.22,P>0.05),超标率差异无统计学意义(χ2=1.90,P>0.05)。监测的部分肉类食品出现铅、镉2种污染物联合超标现象。结论漯河市畜产品总体质量是好的,但部分畜产品存在一定的安全隐患,建议监管部门强化监管,确保畜产品质量安全。
Objective To understand the pollution status of lead, cadmium and total mercury in livestock products in Luohe City, and to provide the basis for food safety risk assessment. Methods A total of 102 samples of 4 kinds of livestock products including meat, liver, kidney, egg and milk in Luohe City were collected to test the contents of lead, cadmium and total mercury in heavy metals. Results The overall detection rate of lead, cadmium and total mercury in 102 samples monitored in 4 years was 61.8%, the overall over-standard rate was 1.6%. The overall detection rate of 4 consecutive years was statistically significant (χ2 = 6.88, P <0.05). There was significant difference between the overall rate of over-standard rate (χ2 = 9.44, P <0.05). Lead, cadmium and total mercury were the highest in the three kinds of heavy metal pollutants, which reached 48.0% and 3.9%, respectively. There was no significant difference in the detection rates of lead, cadmium and total mercury (χ2 = 11.59, P> 0.05). There was no significant difference between the two groups (χ2 = 5.21, P> 0.05). The detection rate of liver and kidney foodstuffs in different kinds of livestock products was the highest (100.0%). The highest over-standard rate was meat food, the exceeding standard rate was 2.9%, and the difference was not statistically significant (χ2 = 9.22, P> 0.05), there was no significant difference between the rate of exceeding the standard (χ2 = 1.90, P> 0.05). The monitoring of some meat foods lead, cadmium two kinds of pollutants combined with excessive phenomenon. Conclusion The overall quality of livestock products in Luohe City is good, but some livestock products have some potential safety problems. It is suggested that regulatory authorities should strengthen supervision and ensure the quality and safety of livestock products.
