摘　　要：目的 了解平顶山市亚硝酸盐在散装熟肉制品中的使用状况,关注食品卫生安全,保障居民身体健康。方法在市区和几个县区各抽取3~5个监测点（市场）,各监测点采集散装熟肉制品1份以上进行亚硝酸盐残留量测定。结果2011-2013年共采集、检测熟肉制品样品344份,检出亚硝酸盐残留量331份,检出率为96.2%;超标94份,超标率为27.3%。2011-2013年3年间残留量差异无统计学意义（t=1.106,P=0.270）,超标率差异有统计学意义（χ2=16.44,P=0.000）,城乡间超标率差异无统计学意义（χ2=0.406,P=0.524）,猪肉、牛肉超标率差异有统计学意义（χ2=20.832,P=0.000）,羊肉、牛肉超标率差异有统计学意义（χ2=12.423,P=0.000）,牛肉超标情况显著高于猪肉及羊肉超标情况。结论 平顶山市散装熟肉制品亚硝酸盐污染超标情况较为严重,其中牛肉超标率最高,严重影响人民群众身体健康,应引起社会高度重视。Objective To know the application of nitrate in bulk cooked meat products of Pingdingshan city, pay attention to food health safety, guarantee the health of the residents.

Results 344 samples was selected and checked in 3 years, residual quantity of nitrite detected in 331 samples, the detection rate was 96. 2% ; resid- ual quantity of nitrate over - standard in 94 samples, the detection rate was 27.3%, difference of over - standard rate in 3 years from 2011 to 2013 was statistically significant （t = 1. 106, P =0. 270）, difference of over- standard rate was no obvious significance （X2 = 16.44, P = 0. 000）, difference between urban district and counties was no obvious significance （X2 = 0. 406, P = 0. 524）, difference of over - standard rate be- tween pork and beef was statistically significant （X2 = 20. 832, P = 0. 000）, it is the same between mutton and beef （X2 = 12. 423, P =0. 000）, the over - standard rate in beef is much higher than that in pork and mutton. Conclusions The over - standard rate in bulk cooked meat products is serious, among which beef is most serious, the situation has seriously affects the peopleg health, which should be highly valued socially.
