SEOUL, South Korea (AP) -- Investigators in South Korea report finding more tainted food imports from China.
South Korean officials say high levels of the industrical chemical melamine (MEL'-uh-meen) were found in Nabisco's Ritz cracker cheese sandwiches and in rice crackers made by another company.
Melamine has now been found in six imported products in South Korea. South Korea is banning imports of all Chinese-made food products containing powdered milk.
The Illinois-based maker of Nabisco Ritz crackers, Kraft Foods, did not immediately return messages left seeking comment.
Also today, Anglo-Dutch food giant Unilever started recalling some of its Lipton-brand milk tea powder in Hong Kong and Macau. The move came after traces of melamine were found in batches of Lipton's 3-in-1 milk tea powder.
The state-run China News Service reports the arrests of 27 people in connection with the scandal.
