China probes use of formaldehyde to keep cabbages fresh

Authorities in China have launched an investigation into reports of formaldehyde being used to preserve the freshness of cabbages for human consumption.

Officials in the north-eastern Hebei province confirmed that they had verified footage showing individuals dipping cabbages in a solution before loading them onto trucks for transportation.

An environmental blogger first released the footage last week. Using formaldehyde, a colourless chemical used for preserving biological specimens that is known to cause cancer, for keeping food fresh is strictly prohibited in China.

China is the world's largest producer of cabbages, most of which are exported to neighbouring countries in Asia.

Police have taken legal action against the individuals involved, according to state media.

Officials are now moving swiftly to prevent panic and restore confidence by carrying out spot checks on markets across the country.

Chinese state media says investigators will also establish how widespread the practice is and take measures to trace affected vegetables.

Local authorities in Kangbao county said in a statement issued on Saturday: "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."
