Results： As to metals pollution, the over - limit rate was 3.75% （12/320） for lead, 2.50% （6/240） for cadmium, 31.00% （31/3100） for aluminum. While the over- limit rate of food addi- tives was 4.52% （14/310） , including nitrite（5.00% ） , sodium saccharin（ 15.56% ） , benzoic acid and sorbic acid （6.67%）. The over - limit rate of vegetable residues was 5.00% and methamidophos was not detected. In addition, the prohibited additives and mycotoxins were found in the limited range. Conclusion： The overall level of chemical contaminations in market food was low, but there are still contamination in some food, more attention should be paid to take specific measures to strengthen supervision to ensure public health.
