Recently, a subsidiary of Shuanghui Development Holdings was exposed for exceeding the antibiotic limit in pork by 37.5 times, sparking widespread attention.
According to reports from Chinese media, the Market Supervision Administration of Heilongjiang Province released a notice on May 14, 2026, regarding the seventh round of food safety supervision and sampling information for the year 2026. It was reported that the “pork tenderloin” produced by Wanguishuanghui Beidahuang Food Co., Ltd. was found to be substandard due to the exceeding levels of lincomycin. The test report showed that the lincomycin content in this batch of products was as high as 7700 ug/kg (the standard value is ≤200ug/kg), exceeding the limit by 37.5 times. Wanguishuanghui Beidahuang Food Co., Ltd. initially raised objections to the authenticity of the samples, but after assessment, the objections were deemed invalid, confirming the substandard conclusion.
Tianyancha data shows that the company in question was established in 2008, with Shuanghui Development holding a 75% stake and the state-owned enterprise Beidahuang Group holding a 25% stake. The company mainly operates in pig slaughtering and meat processing business. The legal representative and chairman of the board is Ma Xiangjie, the current director and CEO of Shuanghui Development, making it an “important non-wholly-owned subsidiary” of Shuanghui Development.
Lincomycin, as explained by experts, is a type of lincosamide antibiotic produced by streptomyces, which can inhibit bacterial protein synthesis. However, prolonged or excessive intake of lincomycin may lead to gastrointestinal reactions, allergic reactions, abnormalities in the blood system, and even side effects on the cardiovascular system.
In response to this incident, on May 26, the first trading day following the announcement, Shuanghui Development’s A-share stock plummeted at the opening, reaching a low of 24.35 yuan during the trading session, marking a nearly 7-month low. The closing price fell by 5% to 24.52 yuan per share, resulting in an evaporated market value of approximately 4.47 billion yuan in a single day.
On May 28, Henan Shuanghui Development issued an apology statement, stating that a special task force had been set up to conduct a comprehensive investigation at Wanguishuanghui Beidahuang Food Co., Ltd. In the next step, the company will “strengthen source control, increase testing frequency, and improve full-chain traceability management” in all pig slaughterhouses under Shuanghui Development.
As a leading meat processing enterprise in mainland China, Shuanghui has been involved in multiple food safety issues.
In April 2022, a consumer reported on the Black Cat Complaints Platform that there were sharp foreign objects in Shuanghui’s ham sausages, which caused tongue injuries. The incident quickly became a hot search topic, triggering widespread public outcry.
In March 2022, irregularities in the production workshop of Nanchang Shuanghui Food Co., Ltd., a wholly-owned subsidiary of Shuanghui Development, were exposed. Issues such as dark and foul-smelling work clothes, pork chops being directly bagged on the ground, towels used for wiping meat being washed with murky water, careless disinfection procedures, and a lax air shower system were highlighted and went viral on Weibo.
On March 15, 2011, a subsidiary of Shuanghui – Henan Jiyuan Shuanghui Food Co., Ltd. was reported to have illegally used the banned drug “clenbuterol” in the production of ham sausages. This incident caused significant damage to Shuanghui Development, leading to a halt in trading for over a month due to a stock market plunge and losses of 10.3 billion yuan in market value in a single day.
