The detection rates of rice, flour and flour were significantly higher than those of egg and egg products (χ2 = 186.21, P <0.01). Excess standard rate was 2.04%. There was no significant difference in the test standard of cadmium between rice, flour and noodles, egg and egg products (χ2 = 2.68, P> 0.05).
