Q-F · Fraud2008 Chinese melamine milk scandal
Melamine faked the protein in baby formula. It fooled the nitrogen test, not the kidneys.
The fifth quadrant, where the thing was never real. The tell is that the story is too clean.
Why this room
The event sits in qf because the product's central claim was never real: the measured protein content of the adulterated formula was manufactured, not present. Standard protein assays infer protein from total nitrogen and cannot distinguish nitrogen from protein from nitrogen from a non-protein source, so adding melamine produced a falsely high protein reading in a diluted or substandard product. The tell is the clean number: watered-down milk that kept passing the specification test, across 22 producers, for months. The failure was one of verification rather than of engineering or of models, and the deception ran the length of the supply chain from collection stations to branded infant formula.
The record
- China's Ministry of Health reported 294,000 children affected as of 1 December 2008, of whom 51,900 were hospitalised, and 6 deaths.certain
- About 22.4 million children were screened in the national response to the contamination.high
- Melamine was found in Sanlu infant formula at up to 2,563 mg/kg, with random samples ranging from 150 to 4,700 mg/kg (median 1,900 mg/kg).high
- 22 producers of powdered infant formula were found to have melamine-contaminated product; about 9,000 tonnes of milk powder were recalled and more than 2,000 tonnes seized.high
- Sanlu detected melamine in its products in June 2008 and reported it to local government in August 2008, but the provincial government was not notified and public reporting did not begin until 9 September 2008; parents had complained of sick infants from December 2007.high
