The Hong Kong government said it has found excessive amounts of the industrial chemical melamine in another batch of eggs from mainland China.

A statement late Tuesday said the government found 4.7 parts per million of melamine in the eggs from the northeast China's Jilin province. Hong Kong's legal limit is 2.5 ppm.

China has been struggling to get melamine out of its food chain after the industrial chemical was found in infant formula and other dairy products. Six babies died and nearly 300,000 were sickened by melamine-tainted formula.

Chinese agricultural officials have said contaminated chicken feed could lead to melamine-tainted eggs.

The Jilin egg producer could not be immediately reached for comment.
