Hong Kong testers discovered high levels of melamine in one brand of Chinese eggs, prompting Hong Kong authorities to expand their testing to include meat products imported from China, AP reported. Hong Kong testers had discovered 4.7 parts per million of melamine in eggs produced by a division of Dalian Hanwei Enterprise Group. The legal limit for melamine in foodstuffs in Hong Kong is 2.5 parts per million. Hong Kong’s Secretary for Food and Health, York Chow, said the melamine may have come from the feed given to chickens. Hong Kong has asked for assistance from the mainland’s food safety agency to isolate the source of the melamine. The chemical melamine is at the heart of an ongoing dairy scandal that has killed four infants and sickened 53,000.
