Mengniu, China's leading dairy products manufacturer, has announced that it would increase the prices of some of its products to adjust them to rising costs.

Speaking to China Daily, Mengniu's assistant spokesman Ji Xiaodong said that the decision to increase prices wasn't astonishing as the company regularly adjusts prices.

However, he confirmed that price increases wouldn't apply to all products.Speaking on the topic, Xiaodong said, "We will raise the price of some products, mainly pasteurized milk, but the price hikes will not apply to all our products."

The announcement of price increases has come as Chinese food safety watchdog found high levels of a cancer-causing toxin, called aflatoxin, in milk produced by the company.

According to World Health Organization (WHO), aflatoxin can raise the risk of cancer, including liver cancer.

Sales of Mengniu's milk and other dairy products milk have slipped considerably since the food safety watchdog revealed the results of its tests.
