Methods 2009 to 2010 in Mianyang City and three counties (cities) sampling of various types of food to carry out the monitoring of 59 indicators of metal pollutants, mycotoxins, food additives, rare earth elements and pesticide residues. Results A total of 792 food samples were tested, 632 were qualified with a pass rate of 79.80%. The exceeding rate of metal was 26.10% (65/249), of which, the excessive aluminum rate was 51.35% (19/37), the excessive lead rate was 19.42% (40/206), the excessive cadmium rate was 2.91% (6/206) The rate was 1.94% (4/206). Pesticide residues exceed the standard rate of 42.62% (78/183), of which vegetable over-standard rate of 42.65% (58/136), fruit over-standard rate of 40.00% (4/10), mushroom over-standard rate of 43.24% (16/37) The main products were carbofuran (20.88%), parathion (20.22%), methamidophos (15.38%) and dichlorvos (14.21%). The exceeding rate of food additives was 9.66% (17/176). Benzoic acid (26.67%), nitrite (25.00%) and sulfur dioxide (9.68%) were the main pollutants in the over standard projects. No harmful substances in the food, banned substances, mycotoxins and rare earth elements monitoring project exceeded the standard. Conclusion Mianyang City food by metal, food additives, pesticide residues pollution is more prominent, the relevant departments should strictly strengthen supervision and management.
