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.
