China probes use of formaldehyde to keep cabbages fresh

Chinese authorities are investigating allegations that cabbages were preserved using formaldehyde, a chemical known for its carcinogenic properties. The probe began after an environmental blogger shared footage showing individuals dipping cabbages in a formaldehyde solution before transporting them. Formaldehyde, primarily used to preserve biological specimens, is strictly prohibited for food preservation in China.

The country is the world's largest cabbage producer, with most crops exported to neighboring Asian nations. Police have already taken action against those involved, and officials are conducting spot checks in markets nationwide to ensure compliance. Chinese state media reports that investigators will determine the extent of the practice and take necessary steps to trace affected vegetables.

Local authorities in Kangbao county, where the incident occurred, stated that any violations will be punished strictly to guarantee the safety of the vegetable supply. Major markets in Beijing, such as Xinfadi market, have confirmed they have investigated their cabbage sources and found no instances of the prohibited practice. The incident has sparked significant media coverage in China, with critics condemning the wholesalers for prioritizing profit over consumer health.

China generates over 30 million tonnes of cabbages annually, accounting for nearly half of the global production. While formaldehyde exposure in high concentrations can cause cancer, the impact of low-level exposure remains less understood, according to the American Cancer Society.
