Among the 7 types of food, sugar, vermillion and spice samples were all qualified, and part samples of dried vegetables, dried edible fungi and algae, starch and yuba were found to exceed the standard. Day lily of dried vegetables exceeded the standard by 33.31%. Tremella of dried edible fungi and algae exceeded the standard by 20.00%, starch and yuba exceeded the standard by 7.43% and 1.33%, respectively. The foods with excessive sulfur dioxide had been promptly notified to the school, risk warnings had been made, and safety hazards had been eliminated in time. Conclusion Among the ingredients purchased in the school canteen, the excessive situation of sulfur dioxide residues in day lily, tremella, starch and yuba is serious, which should be strengthened the supervision and management.
