China Investigates Formaldehyde Use on Fresh Cabbages

Authorities in China have launched an investigation into reports that a dangerous chemical—formaldehyde—was used to keep cabbages fresh for human consumption.

Video footage posted by an environmental blogger last week showed cabbages dipping in a clear solution before they were loaded onto trucks in northeastern Hebei province. Local officials confirmed the footage and said the practice is prohibited.

Formaldehyde is a colour‑less chemical linked to cancer when people are exposed to high doses. Using it to preserve food poses a risk, say health experts. The incident comes as China remains the world’s largest producer of cabbages, supplying a large portion of Asia.

Police have taken legal action against those involved, and state media reports that authorities are conducting spot checks in markets nationwide to curb the spread and reassure consumers.

The Xinfadi market in Beijing, a key source for fresh produce, said it had investigated its supply chain and confirmed none of the affected cabbages entered its market. Local authorities in Kangbao county warned that any illegal or non‑compliant practices would be dealt with strictly under the law.

The case has attracted widespread media attention, prompting an editorial in the People's Daily that criticised wholesalers for prioritising profit over consumer safety.

China produces roughly 30 million tonnes of cabbages annually, almost half of the global output. The main export markets are Vietnam, South Korea and Russia.
