China Probes Contaminated Milk Powder
Sanlu confirmed an internal company investigation found its milk powder produced between March and August 5 was contaminated by the chemical. Sales of the product were halted August 6, the company said, although the public recall announcement was delayed for more than a month.
Sanlu is defending itself, saying the contamination was caused by milk suppliers rather than the company’s production procedure.
[…] According to Su, the company does not test for tripolycyanamide because China has no national standards for testing milk products for the chemical.
Su said dairies may be tempted to add tripolycyanamide to boost nitrogen levels because tests for nitrogen are conducted to determine protein levels in milk.
