sentence1: Guanshengyuan, a Chinese company that makes children's candy, has stopped selling its popular brand White Rabbit, which is sold nationally in China, after tests confirmed the presence of melamine. Bright foods owns the candy company. Earlier their powdered milk was found to contain melamine which sickened over 53,000 people and was responsible for the deaths of at least four infant children. Guanshengyuan has stopped exporting their goods to the nearly 50 companies overseas that buy them. Melamine has also been found in Hong Kong in baby cereal and vegetable formula made by Heinz. It has also been found in wasabi crackers which are manufactured by the Chinese company, Silang House. Another Chinese food company called Marudai Food Co. has also halted the sales of several items such as meat buns, cream buns and corn crepes made with cream over fears that melamine laced powered milk has contaminated their products. So far there have been no reports of any illnesses associated with Marudai Foods.
sentence2: 4 children died in Hong Kong because of melamine contained in milk.
