Shuanghui Stock Falls 5% After Antibiotic Scandal, May 29

Shuanghui Development (000895.SZ) faced a major food safety crisis after its subsidiary produced pork with antibiotic residue 37.5 times above safety limits. The contaminated meat already reached consumers before recall. The company apologized May 28 and stock fell 5% on May 26. This marks the second major food safety failure for the meat industry leader in 15 years.

Antibiotic Levels Hit 37.5 Times the Safe Limit

Wangkui Shuanghui North Daqing Food, a subsidiary of Shuanghui Development, produced pork with lincomycin residue of 7700 micrograms per kilogram. China’s safety limit is 200 micrograms per kilogram. The contaminated batch was produced August 27, 2025 and sold at retail stores in Heilongjiang province. The product remained on shelves for months before Heilongjiang market regulators issued a recall notice on May 14, 2026.

Company’s Initial Response Drew Criticism

On May 25, Shuandhui claimed lincomycin is not a mandatory testing item for slaughterhouses and blamed upstream farms for failing to follow drug withdrawal periods. Experts rejected this explanation. Fudan University professor Li Shuguang stated companies must test for drugs they use in supply chains, not rely solely on government inspections. The subsidiary challenged the test results but regulators upheld the findings as valid on May 28.

Stock Drops as Apology Comes Too Late

Shuanghui stock fell 5% to 24.52 yuan on May 26 after news broke, touching a 7-month low of 24.35 yuan intraday. The next day, shares fell further to 23.89 yuan before recovering slightly to 24.68 yuan. By May 28 close, the stock traded at 24.72 yuan. The company’s delayed apology and initial blame-shifting damaged investor confidence. Long-term lincomycin exposure can cause intestinal damage, allergic reactions, and blood cell reduction.

History of Food Safety Failures Resurfaces

This is Shuanghui’s second major food safety scandal in 15 years. In 2011, CCTV exposed the company’s subsidiary buying pigs fed ractopamine, an illegal growth promoter. The subsidiary Wangkui Shuanghui generated 1.418 billion yuan in revenue and 72.5 million yuan in net profit in 2025, supplying schools, nursing homes, and 900 retail outlets across three provinces. Despite spending hundreds of millions on quality control systems, the company failed to catch the contamination.

Final Thoughts

Shuanghui’s stock fell 5% after its subsidiary shipped antibiotic-tainted pork to consumers, marking a second major food safety failure in 15 years. The delayed apology and initial blame-shifting eroded investor trust in the company’s quality controls.
