The producer of China's White Rabbit brand candy on Friday announced the suspension of domestic sales of its products, which are suspected of melamine contamination.
The Guanshengyuan company had previously recalled all exports, some of which tested positive for melamine in Singapore earlier this week.
Ge Junjie, vice manager of the Shanghai Guangming Dairy and Food Company, which owns Guanshengyuan, said the suspension of sales of White Rabbit candy reflected "the company's conscientious decision to protect consumers".
The company's candy is still undergoing tests for melamine by the Shanghai Entry-Exit Inspection and Quarantine Bureau.
The bureau could not provide the test results on Friday morning.
"We decided to halt all sales of White Rabbit candy, although the test results have not yet come out," said Ge.
