Hong Kong ? British candy maker Cadbury announced a recall Monday of chocolate made in its Beijing factory after it was found to contain melamine, the industrial chemical that has sickened tens of thousands of Chinese children.

The 11 recalled items were sold in parts of Asia and the Pacific, the company said in a statement. Cadbury’s chocolates sold in the United States were not affected, said a spokesman for Hershey’s, Cadbury’s sole U.S. distributor.

Meanwhile, Kraft Foods, the maker of Oreo cookies, and Mars, the maker of M&Ms and Snickers candy, questioned the findings of Indonesian tests that identified melamine in samples of their products made in China.

Both Kraft Foods and Mars said they would comply with an Indonesian recall but planned to conduct their own tests and look into the possibility the tainted products were counterfeits.
