SEOUL, South Korea (AP) -- South Korean investigators say they have found high levels of melamine in two more Chinese-made food products.
The Korea Food and Drug Administration said Tuesday that melamine was found in Nabisco Ritz cracker cheese sandwiches and in rice crackers made by Danyang Day Bright Co.
Melamine has now been found in six products imported to South Korea, including Misarang snacks made in China and in Chinese-made nondairy creamer imported from Hong Kong. South Korea has banned imports of all Chinese-made food products containing powdered milk.
Melamine -- used to make plastics and fertilizer -- can be deadly in high doses and is blamed for the deaths of four babies in mainland China.
