Chinese authorities have initiated an investigation into allegations of formaldehyde being used to maintain the freshness of cabbages intended for consumption. Officials in the northeastern Hebei province have confirmed the verification of footage depicting individuals treating cabbages with a solution prior to their transportation.
The footage was initially released by an environmental blogger last week. The use of formaldehyde, a colorless chemical classified as a carcinogen, for food preservation in China is strictly prohibited by law.
China is the world's largest producer of cabbages, with a significant portion of its harvest exported to neighboring Asian countries. State media has reported that police have taken legal action against those implicated in the practice.
In response to the incident, officials are conducting spot checks on markets nationwide to prevent potential public alarm and to ensure consumer confidence. Investigators are also working to determine the extent of the practice and to trace any affected vegetables.
Local authorities in Kangbao county issued a statement on Saturday, asserting that "Any illegal or non-compliant practices discovered will be dealt with strictly in accordance with the law to ensure the safety of the vegetable supply." The Xinfadi market in Beijing, a major hub for fresh produce, stated that it had investigated its cabbage sources and confirmed that none of the affected vegetables had entered its supply chain.
The incident has garnered considerable media attention within China. An editorial in the People's Daily criticized the wholesalers involved, stating they "focused solely on their immediate economic interests while completely disregarding the lives and health of consumers. [They] crossed a legal red line and breached the moral bottom line."
China's annual cabbage production exceeds 30 million tons, accounting for nearly half of the global total. Key export destinations include Vietnam, South Korea, and Russia.
According to the American Cancer Society, exposure to high quantities of formaldehyde in occupational settings has been linked to certain types of cancer in humans, though the effects of consuming small amounts remain less clear.
