China Cracks Down on Formaldehyde-Treated Cabbage in Food Safety Sweep

China’s State Council Food Safety Office, along with the Ministry of Agriculture and Rural Affairs and the State Administration for Market Regulation, has issued nationwide guidance for local authorities to strictly investigate and crack down on formaldehyde-treated cabbage, following an undercover video that exposed the illegal practice in Hebei Province. The Xinhua News Agency reported that the three departments directed local authorities to trace the flow of contaminated cabbage and prevent it from entering the market.

The Investigation That Sparked a National Response

The controversy began on August 22 when self-media blogger “Yulie Qige” posted an undercover video showing workers at cabbage loading sites in Kangbao County’s Tunzhen Township, Zhangjiakou City, Hebei Province, dipping cabbage roots into containers labeled “formaldehyde solution” before loading them onto trucks for long-distance transport. The workers stated the practice was meant to preserve freshness for 2-3 days during transport to reduce rot, and a truck driver revealed the cabbage was destined for Suqian, Jiangsu Province.

That same afternoon, the Kangbao County government issued an official notice confirming the video’s content was true, describing it as an illegal act by purchasers to preserve vegetables during transport. Public security authorities took compulsory measures against the individuals and vehicles involved, with the case under further investigation.

The blogger’s follow-up video revealed that authorities in Fuyang City, Anhui Province tested the same batch of cabbage and found formaldehyde levels exceeding standards, leading to the batch being sealed. As CCTV reported, the State Administration for Market Regulation released a statement on the evening of August 23 confirming the multi-departmental response.

Nationwide Crackdown and Market Screening

On August 23, the three central departments issued guidance for a nationwide crackdown, ordering special inspections and market screening of cabbage and other perishable vegetables. The State Administration for Market Regulation stated that any illegal or non-compliant behavior found would be “severely punished without mercy” to safeguard the people’s dietary safety.

The People’s Daily published a commentary calling the use of formaldehyde for preservation “vile in nature and utterly absurd,” emphasizing that food safety must be handled swiftly and strictly. The commentary stressed the urgent need to trace the transport chain to the end, intercept in time, and prevent more people from buying problematic vegetables.

Local authorities across Zhangjiakou have responded aggressively. According to The Paper, multiple counties including Kangbao, Wanquan, Chicheng, and Zhangbei issued public reward announcements for reporting vegetable quality and safety violations, with rewards ranging from 2,000 to 3,000 yuan.

Market Testing and Consumer Protection

Major wholesale markets across the country have launched emergency testing protocols. Shanghai’s vegetable group began formaldehyde-specific testing for all incoming cabbage at its wholesale markets starting August 22, with all tests negative so far. Beijing’s Xinfadi market conducted batch-by-batch rapid testing for formaldehyde on all incoming cabbage with no contaminated samples found.

Nanjing’s Zhongcai Vegetable Market conducted 53 batches of tests, all negative, and banned all cabbage from Kangbao County. As Jiemian News reported, Suqian’s Zhonghe Agricultural Products Market confirmed that tests on the batch from Hebei Kangbao were all qualified, with three rounds of testing conducted.

Economic Fallout for Compliant Farmers

The incident has caused significant collateral damage to compliant farmers and cooperatives in Kangbao County. According to Yangtze Evening News, one vegetable cooperative’s daily shipments dropped from 1,500 packages to fewer than 300, with orders from Wenzhou and Guangzhou supermarkets cancelled and supermarkets removing cabbage products from shelves.

Mr. Xing, head of a large vegetable cooperative in Kangbao County, told Dahe Daily that his cooperative uses cold-chain logistics and has never used formaldehyde. “Trucks that ship from cold storage don’t use that (formaldehyde),” he said. “Once you cool it in the cold storage to 2-3 degrees, shipping to Shenzhen or Guangzhou takes about four days and it basically won’t spoil.”

However, he noted that the market no longer accepts verbal assurances. “The biggest problem right now is that the market doesn’t want the goods. They don’t accept verbal assurances, only written proof,” he said. The Kangbao County agriculture bureau has announced it will conduct sampling tests on cold-storage cabbage and issue “no formaldehyde residue” certificates for batches that pass, allowing cooperatives to resume sales.

Historical Context and Regulatory Gaps

This is not the first “formaldehyde cabbage” incident in China. In 2012, Xinhua News Agency investigated cabbage purchasers in Qingzhou, Shandong Province using formaldehyde for preservation. Formaldehyde is classified as a Group 1 carcinogen by the World Health Organization’s International Agency for Research on Cancer, and China’s Food Safety Law and Agricultural Product Quality Safety Law explicitly prohibit its use in any stage of agricultural production, purchase, circulation, or sales.

The incident highlights gaps in supervision of the agricultural product circulation chain, particularly the purchase, loading, and long-distance transport segments, which are less regulated than production and retail. As CNR reported, the People’s Daily commentary called for moving regulatory oversight forward to prevent problems before vegetables are loaded for transport.

What to Watch For

As the investigation continues, key questions remain: How widespread was the practice? How much contaminated cabbage has already entered the market? And what systemic reforms will follow to close the regulatory gaps in the agricultural supply chain? The nationwide inspections ordered by the three departments, combined with the reward programs for whistleblowers, signal a determination to address these concerns. For consumers, the immediate takeaway is that major markets across the country are now conducting formaldehyde-specific testing on cabbage, providing an additional layer of protection as the investigation unfolds.
