HONG KONG -- British candy maker Cadbury is recalling 11 types of Chinese-made chocolates laced with an industrial chemical.

Cadbury says the recalled chocolate products were distributed in Taiwan, Hong Kong and Australia.

Authorities believe suppliers in China added melamine as a way to help their products pass quality tests for protein.

The scandal broke this month after authorities found contamination in Chinese-made baby formula. Four infants have died and some 54,000 have gotten sick. Later tests found melamine in products ranging from yogurt to candy to pastries.

Meanwhile, U.S. companies Kraft Foods and Mars have recalled Chinese-made Oreos, M&Ms and Snickers in Indonesia.

China’s official news agency says police have arrested 22 people and seized more than 480 pounds of melamine. They say the melamine was produced in illicit plants and sold to breeding farms and purchasing stations.
