Authorities in China have launched an investigation into reports that formaldehyde is being used to preserve cabbages for human consumption. Officials in the northeastern Hebei province confirmed they verified footage showing individuals dipping cabbages in a solution before loading them onto trucks.
The footage, initially released by an environmental blogger last week, shows a practice strictly prohibited in China. Formaldehyde is a colourless chemical known to cause cancer, and its use for preserving food freshness is illegal.
State media reports that police have taken legal action against those involved. Officials are now conducting spot checks in markets nationwide to prevent panic and restore confidence. Investigators will also determine how widespread the practice is and trace affected vegetables.
Local authorities in Kangbao county stated on Saturday 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." Beijing's Xinfadi market, a major fresh produce source, has investigated its cabbage supply and stated no affected vegetables entered its market.
