In brief
Authorities in China have launched an investigation after footage showed cabbages doused in formaldehyde before transport. The chemical, used for preserving biological specimens, is prohibited for food use. The incident has triggered police action, market checks and a demand for transparency. China, the world’s largest cabbage producer, faces scrutiny over the safety of its export supply. Experts note that while high exposures are linked to cancer, small amounts may still pose risks.
