It’s been almost four years since China’s dairy industry suffered the melamine contamination crisis, but chemical contaminations continue to plague the industry. At the end of June, Shanghai-based Bright Dairy & Food recalled a batch of its Ubest-brand milk products after an investigation revealed the products may have been contaminated with lye, according to the city’s quality and technical supervision bureau.
An investigation by the bureau found food-grade lye that was used to clean pipes had leaked into and contaminated a production line at one of the company’s plants due to a mechanical malfunction during regular maintenance procedures, according to a Shanghai city bureau spokesman.
