With the convening of the 2008 Olympic Games, Beijing took the lead in establishing a food traceability system. All Olympic food can be inquired on the system terminal through the bar code on the food packaging, and relevant information such as food manufacturers, transporters and distributors can be inquired back. Once the safety problems of related foods are found, the system can be used to find the relevant manufacturers in all aspects of product production. Dacheng Food (Asia) Co., Ltd., as a licensed chicken supplier for the 2008 Beijing Olympic Games, has always been a participant and advocate of food safety projects. At the beginning of 2009, Dacheng Food completed its representative mission in the domestic market, that is, the food safety management system that can be traced from farm to table-the source transparent chicken food safety guarantee system, and successively launched the "sister kitchen" brand products represented by the source traceability security code. At the same time, "Sister Kitchen" products have landed in Tianjin, Shanghai, Dalian, Beijing and other markets, opening the peace of mind of Dacheng Food. Through the anti-counterfeiting code on the product packaging, consumers can send short messages or log in to sister chef official website, and they can conveniently find all the process information of the purchased chicken products from feeding to eating, including: the breeding farm of broilers, the owner's name, the time when chicks enter and leave the farm; Feed information for raising chickens; Information on the production and quality inspection of electric slaughterhouses and batches of fresh meat; Food deep processing information and other content, so that consumers can truly enjoy traceable safe food with confidence.
