Results In 2017, the detection rates of lead and cadmium were 94% and 70.50%, respectively. In 2018,the detection rates were 83.50% and 97%. The results of lead detection in food showed that French fries exceeded the standard by about 0.4 times, followed by tea, popcorn, chicken liver and pig liver. A total of 200 samples and 9 kinds of food were monitored. Cadmium was detected in tea, fresh vegetables, flour, wheat, rice, pig kidney and pig liver. The content of cadmium in pig kidney exceeded the standard by 0.8 times, followed by pig liver, fresh edible fungi and wheat. Conclusion According to the analysis, the heavy metals in food in Shenzhen are relatively light, but cadmium and lead in meat products, cereals, fried dough sticks, steamed bread and other cooked rice noodles are relatively high.
