RESUMO
Objective To investigate the status of chemical contaminants in food in Hebei District, Tianjin, find hidden food safety hazards in time, determine the types and sources of pollutants, and provide a scientific basis for the early warning of food safety risk. Methods The detection results of chemical pollutants in nine categories of foods continuously monitored in the food safety risk monitoring in Hebei District from 2016 to 2018 was statistically analyzed. Results A total of 219 samples were tested, of which 22 were unqualified, with the unqualified rate of 10.05%. The pollution rate of chemical pollutants in nine categories of foods was 6.35%-12.7% in the three years from 2016 to 2018, and there was no statistical difference in the pollution rates during the three years (χ2=1.47, P=0.48). Among the nine categories of foods, the disqualification rate in five types of foods was significantly different (2=13.12，P=0.006). The pollution rate of eggs and egg products was the highest at 46.67%, followed by animal viscera in the category of meat and meat products, with the pollution rate being 22.22%. Conclusion The overall risk of chemical contaminants in foods sold in Hebei District was relatively low. However, some foods still contained illegal veterinary drugs and prohibited drugs. In addition, heavy metals and food additives exceeded the standards in some foods. The detection rates of veterinary drugs and banned drugs in eggs and egg products, and meat and meat products were relatively high.
