In 2009, Dacheng Food (Asia) Co., Ltd. officially launched the "transparent source" food project and launched the "sister kitchen" chicken food brand. Its products include: sister kitchen fresh chicken products, sister kitchen cooked chicken products and sister kitchen brand concept stores. At present, every package and box of chicken products sold in the market as "sister kitchens" can be easily known through mobile phones or the Internet as long as the security code on the package is input, including ① the time of farms, breeders, incubation and slaughter; (2) the production information of the compound feed used; ③ Information on the production and quality inspection of electric slaughterhouses and batches of fresh meat; (4) Food deep processing information, so that consumers can rest assured to enjoy traceable safe food. Dacheng's food safety traceability system is not only suitable for chicken producers, but also for producers of animal protein products such as meat, eggs and milk. Therefore, the completion of this system will play a positive role in upgrading the whole food industry, reconstructing the industry image and restoring consumer confidence.
