SHANGHAI -- Shanghai-based Bright Dairy & Food is recalling a batch of its Ubest-brand milk products after an investigation revealed that the products may have been contaminated with lye, according to the city's quality and technical supervision bureau.
An investigation conducted by the bureau Wednesday found that food-grade lye that was used to clean pipes had leaked into and contaminated a production line at one of the company's plants on Monday, a bureau spokesman said early Thursday.
The contamination was caused by a mechanical malfunction during regular maintenance procedures, said the spokesman.’
