Hebei Cabbages Were Dipped in Embalming Fluid. It's Not the First Time.
A blogger's field video exposed farmers in Hebei dipping cabbage roots in formaldehyde — the same chemical used to preserve lab specimens — and reignited a recurring food-safety debate.
On social media, the video has a terrible kind of clarity: a farmer beside a truck, dipping the pale cut end of a cabbage into a bucket, then tossing it onto the pile. The field was in Kangbao county, Hebei, and the liquid, the county later confirmed, was formaldehyde.
Formaldehyde is the chemical in the jars of biology class. Its familiar solution form, 福尔马林 (fúlǐmǎlín), is what labs use to preserve tissue specimens. It is sharp-smelling, colorless, and very good at keeping a severed edge looking fresh. That is precisely the problem. Dipped on a cabbage root, it holds back the wilting and browning that would otherwise tell a buyer the vegetable is past its best. It is also a Group 1 carcinogen, and it is banned from food.
The exposure came from a blogger, 渔猎齐哥 (Yuliè Qígē), not from a government inspector or a newsroom. The county moved quickly after the video spread, confirming the report and taking measures against those involved. By the end of the week the blogger was back with an update: spot checks had begun in several regions, and, in his phrasing, "问题白菜估计以后吃不到了" — the treated cabbage, he guessed, would not be reaching tables any longer.
The most watched reaction came from Hu Xijin, the former Global Times editor whose account has more than 49 million followers. He thanked the citizen investigators by suggesting they had shamed the professionals. Mainstream journalists, and the public officials whose job is food safety, had failed to catch what a phone camera found in a field. The internet, he said, was the "main front" of public oversight.
That is the part with the longer half-life. The formaldehyde cabbage trick is not new; one popular platform noted this week that the method was first exposed fourteen years ago. It keeps coming back because it is cheap, because fresh-looking produce sells, and because the supervision that catches it tends to arrive only after a video has gone viral. An inspector can stop one truck; a trending hashtag can pause a season. But unless testing becomes routine rather than reactive, the next harvest only needs to wait for the cameras to turn away.
For now, the immediate result is real: a county has admitted fault, checks have begun, and the people who did the work were not employed to do it. That is both a victory for crowdsourced watchdogs and an indictment of the systems that keep requiring them.
