Shuanghui Apologizes After Pork Antibiotics 37.5x Over Limit
China’s largest meat processor, Shuanghui Development (000895.SZ), issued a public apology on May 28 after a subsidiary’s pork products were found to contain antibiotic residues at 37.5 times the legal limit. The scandal, uncovered by the Heilongjiang Provincial Market Supervision Administration, has sent the company’s stock tumbling and reignited concerns about food safety standards in China’s pork industry.
What Happened
According to a food safety notice from the Heilongjiang Provincial Market Supervision Administration (2026 Issue No. 7), pork products — specifically “pig rump meat” — produced by Wangkui Shuanghui Beidahuang Food Co., Ltd. were found to contain lincomycin residues at 7.70×10³ μg/kg. The legal limit under China’s national standard GB 31650-2019 is just 200 μg/kg, meaning the antibiotic concentration exceeded the maximum allowable level by 37.5 times, as The Paper reported.
The affected batch was produced in August 2025. Lincomycin, a lincosamide antibiotic used to treat bacterial infections in livestock, can cause gastrointestinal distress, allergic reactions, liver and kidney dysfunction, and contribute to antibiotic resistance when consumed in excessive amounts over time.
Company Response and Stock Impact
Shuanghui Development initially challenged the authenticity of the sample, but the regulator ruled the challenge invalid. The company later attributed the contamination to upstream pig farming operations that failed to observe mandatory withdrawal periods for veterinary drugs, according to Yicai.
“Lincomycin was caused by veterinary drug use in upstream pig farming operations. We will strengthen management of pig suppliers and increase the frequency of veterinary drug residue testing,” a Shuanghui securities representative told Yicai.
On May 26, Shuanghui Development’s stock fell over 5% intraday, closing down 3.9% at 24.8 yuan per share, with total market capitalization dropping to approximately 85.9 billion yuan (859亿å ), as reported by Yicai.
On May 28, Henan Shuanghui Investment Development Co., Ltd. issued a formal public apology through its official WeChat account, pledging to strengthen quality control measures across its supply chain, as confirmed by The Paper’s follow-up report.
A History of Food Safety Failures
This is not Shuanghui’s first major food safety crisis. In 2011, the company was at the center of the “lean meat powder” (clenbuterol) scandal, which caused sales to plummet by approximately 1.5 billion yuan and wiped out over 10 billion yuan in market value. Chairman Wan Long initially blamed upstream farming before holding a highly publicized “10,000-employee conference” to apologize, designating March 15 as “Shuanghui Food Safety Day.”
Critics argue that the company’s pattern of blame-shifting has not changed. As Jiemian News wrote in a sharp editorial, “Shuanghui’s response attempts to shift responsibility to upstream farming, exposing a mindset of trying to separate itself from the complex food safety chain. For an industry leader that has repeatedly fallen into food safety scandals, this ‘buck-passing’ response not only fails to solve the problem but also drains brand trust.”
Systemic Challenges in China’s Pork Industry
The incident highlights a broader structural problem in China’s pork supply chain. Feng Yonghui, chief analyst at Soozhu.com, noted that lincomycin requires at least a one-month withdrawal period before slaughter to ensure the drug is fully metabolized. However, in China’s fragmented pig farming sector, small and medium-scale farmers often overuse antibiotics to prevent disease in high-density farming conditions, and withdrawal periods are frequently ignored.
An anonymous pig farmer told Yicai that “exceeding the national standard by 37 times is definitely a serious situation. This is not common in the industry.”
Notably, Shuanghui admitted that lincomycin is not a mandatory testing item at slaughter, unlike clenbuterol. The fact that the violation was caught by government inspection rather than internal company testing raises questions about the adequacy of corporate self-regulation.
What’s Next
The Heilongjiang Market Supervision Administration has ordered local authorities to investigate, trace product flows, compel recalls, and punish any illegal activities. The incident may trigger broader industry-wide inspections of veterinary drug residues in pork products across China.
For Shuanghui, the challenge extends beyond regulatory penalties. With revenue declining for five consecutive years and consumer trust once again damaged, the company faces an uphill battle to restore its reputation. Public sentiment, as reflected in comments on The Paper, is unforgiving: “Shuanghui is not a first-time offender!! As a large food enterprise, can a simple apology satisfy the public?”
The coming weeks will reveal whether this incident leads to meaningful reform — or becomes another chapter in a recurring cycle of scandal, apology, and inaction.
