China Investigates Formaldehyde Use on Cabbages
Authorities in China have launched an investigation into reports of formaldehyde being used to preserve the freshness of cabbages for human consumption.
An environmental blogger released footage last week showing individuals dipping cabbages in a solution before loading them onto trucks for transportation. Officials from Hebei province confirmed they had verified the footage.
Using formaldehyde, a colourless chemical that can cause cancer, for preserving food is strictly prohibited in China. The country, the world’s largest cabbage producer, exports most of its yield to neighboring Asian markets.
Police have taken legal action against the operators involved, according to state media. Authorities are also conducting spot checks across markets nationwide to reassure consumers and prevent panic.
Investigators will determine how widespread the practice is and trace affected vegetables back to their origins. Local authorities in Kangbao county stated that any non‑compliant practices will be dealt with strictly under the law to secure the vegetable supply.
Xinfadi market in Beijing, a major source of fresh produce, said that it had investigated its supply chain and confirmed that none of the cabbages in its market were contaminated. The incident has attracted widespread media attention in China.
An editorial in the People's Daily warned that “the wholesalers focused solely on immediate economic interests while disregarding consumer health.” It called the practice a breach of legal and moral standards.
China produces over 30 million tonnes of cabbages annually, about half of the world’s total, exporting to Vietnam, South Korea, and Russia among other countries. The American Cancer Society notes that high formaldehyde exposure has links to certain cancers, though the effects of low‑level exposure remain unclear.
