Foodborne diseases are of major concern for public health. A study on pork products was undertaken to assess the safety status of pork products in China market based on spot check data of pork products in China from 2015 to 2019 (n=22340). The results showed that the percentage of unqualified pork products was decreased from 10.87% in 2015 to 2.44% in 2019 which meant the safety of pork products in China was improved greatly in recent years. According to the statistics on the main factors affecting the safety of pork products, it was found that additives were the main factors affecting the safety of pork products since the detection rate of the additive was 1.62%. It was mainly affected by the type of pork products and the production process. The results also showed that microbial contamination and veterinary drug residues were the main factors affecting the safety of pork products. However, different from microbial contamination, which was affected by season and temperature, the level of veterinary drug residues was mainly related to animal diseases. In addition, heavy metal pollution may have a lasting impact on product safety in a long period of time compared with other factors for it was closely related to environmental pollution of raw material cultivation, although it accounted for only 0.17% of all sampling products.
