Quality must be controlled

One of China's largest milk producers, Mengniu Dairy Co Ltd, is embroiled in yet another food safety scare.

Tests by the General Administration of Quality Supervision, Inspection and Quarantine (AQSIQ) of fresh milk products produced at Mengniu's Meishan plant in Sichuan province found levels of a potentially cancer-causing toxin were more than double the national standard.

Even though the company based in the Inner Mongolia autonomous region apologized to consumers on its website immediately after the scandal, its reputation - and the reputation of China's whole dairy industry - has taken another heavy blow.
