Frozen-food processor Nichirei Corp. said Wednesday it will cut the salaries of its president and other senior officials for three months in a punitive move over imported frozen shrimp that contained banned antibiotics.

Earlier this month, the health ministry said antibiotics had been found in frozen shrimp produced in China, and Nichirei, which imported the products, recalled them from the market.

Imports of food items with the antibiotic chlortetracycline, used for promoting growth, are banned under the Food Sanitation Law.

The monthly salaries of Nichirei President Mitsudo Urano, Chairman Takemoto Oto and director Koichi Maeshima will be cut by 30 percent, and those of two other senior officials by 20 percent, all for three months.
