During the Spring Festival holiday, the Nanhetan Market in Guyuan City, Ningxia Hui Autonomous Region, was bustling with activity. Ma Jianguo, a local resident shopping for mutton, stood at a meat stall and scanned a QR code on a blue tag attached to a lamb leg. Instantly, details of the animal quarantine certificate and meat quality inspection report appeared on his phone. "I used to feel uncertain when buying meat, but now with this QR code 'navigation,' I feel much more assured," he said happily. This sense of security stems from a quiet but significant regulatory overhaul by Guyuan's market supervision authorities. Just before the holiday, the Guyuan Market Supervision Bureau teamed up with the Guyuan People's Procuratorate to introduce a new approach—leveraging big data analytics to precisely "navigate" meat product safety oversight. "In the past, we relied on manual inspections, which often led to oversights. Now, it's like sifting through a sieve—the system automatically cross-references and analyzes multi-dimensional data, including business licenses, purchase records, and consumer complaints from meat vendors across the city," explained an enforcement officer from the bureau. So far, 56 businesses have been identified as key inspection targets. At one mutton and beef shop, an officer pointed to the blue tag on the meat and told customers, "Don’t underestimate this small tag—it contains all the quarantine and inspection details." The shop owner, Master Ma, added, "Though small, this tag represents a safety baseline. Customers now trust it, and it has been a great help to everyone." Since the two departments launched this initiative, consumer complaints related to meat products have dropped significantly, while supplies from licensed slaughterhouses have steadily increased. "This decline in complaints and rise in正规 supplies signal improved market order," said a representative from the Guyuan Market Supervision Bureau. The official also noted that Guyuan has now fully digitized the "dual certificates" for meat products, enabling end-to-end digital monitoring from farming to dining tables. "Every piece of meat now has a digital record," he emphasized. "Technology makes supervision smarter and helps safeguard food safety, allowing residents to enjoy a worry-free holiday."
