On August 23, according to information from Beijing's Fengtai, the Beijing Xinfadi Agricultural Products Wholesale Market immediately initiated a full-chain traceability investigation in response to the fact that some cabbage buyers in Kangbao County, Zhangjiakou, Hebei illegally used formaldehyde solution to keep fresh on August 22. As of the night of August 22, the Xinfadi had undergone thorough inspections. The cabbage involved in the Kangbao County problem had not entered the Xinfadi market, and the capital's “vegetable basket” supply was safe and stable. After the incident came to light, the Xinfadi Market immediately checked all certificates of origin, transport vehicles, and purchase channels for cabbage entering the market one by one. The relevant person in charge of Xinfadi said that the market has long implemented a strict agricultural product entry system and sampling inspection mechanism to confirm that the vehicles and batches involved have not entered the Xinfadi trade. Xinfadi also encrypts the frequency of rapid inspections of pesticide residues and illegal additives in vegetables, preventing any unqualified agricultural products from entering the market, and making every effort to protect the safety of the “vegetable basket” of the citizens of the capital. Currently, there is an adequate supply of cabbage in the Xinfadi market, and they all have standardized certificates of origin and qualified inspection reports.
