HONG KONG—A Chinese snack has been pulled from Hong Kong shelves after health authorities said Wednesday it contained dangerous levels of the chemical at the center of a toxic milk scandal in China.

White Rabbit Creamy Candies, made by Shanghai-based Bright Food Group, contained more than six times the legal limit allowed of the industrial chemical melamine, the Centre for Food Safety said in a statement.

"We have already informed the trade upon announcing the test results... and asked them to stop selling the products concerned. The importer has recalled the affected products," a spokesman said, according to the statement.

The candies were the only one of 67 food and drink products that tested positive for dangerous levels of melamine in the latest batch of tests, the statement said.

No further action would be taken against the retailer or the importer of the snack since new rules were only brought in after the scandal was exposed two weeks ago, the spokesman said.

Authorities in Singapore said late Sunday they also found the potentially deadly chemical in White Rabbit Creamy Candy.

Hong Kong had previously banned several products linked to the scandal.

Melamine, which is usually used in making plastics, was found to have been added to milk formula, sickening close to 53,000 infants in China and four in Hong Kong, authorities have said.

Melamine can make products appear full of protein, but it can be fatal if consumed in large amounts. Four children in China have died.

Several countries have now banned or limited imports of China-made dairy products.
