China traces shipment of 'formaldehyde-dipped' cabbage after viral food-safety video
A video showing cabbages being dipped in a formaldehyde solution before being loaded onto trucks bound for Jiangsu and Anhui has triggered an emergency trace in Hebei's Kangbao County, with police detaining suspects, officials say.
A food-safety scare went viral on Weibo under the hotword #蘸甲醛的大白菜正运往江苏安徽等地# ("Formaldehyde-dipped cabbages are being shipped to Jiangsu, Anhui and other places"), and quickly turned into a formal administrative response.
The short version: footage appeared to show cabbages being dipped in a formaldehyde solution during loading, apparently as a preservation step before long-distance transport. Formaldehyde is not permitted in food-contact or fresh-produce handling in China, and its use in vegetable transport is illegal.
Local authorities in Kangbao County, Hebei, moved fast. In an official notice circulated across platforms, the county government said the video was authentic: "Preliminary verification confirms the situation in the video is true. It was an illegal act by purchasers attempting to preserve vegetables during transport." Police placed the relevant people and vehicles under compulsory measures, and investigators began an emergency trace of where the cabbage had gone. The county also said it would carry out a full inspection of vegetable purchasing, transport, and sales.
On Zhihu, the question "What penalties do the people involved in dipping cabbages in formaldehyde face? Why do such incidents keep happening?" became one of the platform's top-voted topics, reflecting a mix of anger and weary familiarity. The underlying anxiety is rooted in China's long history of food-safety scandals, which means any viral video involving chemicals and fresh produce is treated as urgent national news rather than a local oddity.
The story has not yet produced widely shared Weibo user comments in the scrape, but its rapid climb — and the unusually quick official acknowledgment — shows how seriously the claim was taken. The fear of "what we don't know is on our plate" remains one of the most reliable drivers of Chinese social media outrage.
For international readers, the incident is a window into both the scale of China's food supply chains and the speed with which a single phone video can force a county government to publicly account for what is being loaded onto a truck.
