市販国産鶏卵のフィプロニルをはじめとする残留農薬の調査

摘要

In some of the EU member countries, Hong Kong, South Korea, and Taiwan, chicken eggs contaminated by fipronil used without authorization were identified and widely reported. The Ministry of Health, Labour and Welfare of Japan stated no contaminated imports had been found in the country while promising to strengthen monitoring chicken eggs coming from those areas. Meanwhile, there are no reports published to show whether or not chicken eggs produced in Japan contain such pesticide. This paper, therefore, examined 50 commercial brands of chicken eggs produced and sold in Japan to identify 116 kinds of agricultural chemicals including fipronil.None of these brands contained fipronil. Among the 50 brands studied, 45 brands did not include any of the 116 kinds of agricultural chemicals. Spinosad was detected in the four brands with the concentration levels ranging from a trace to 0.019 ppm. Diflubenzuron was found at 0.005 ppm in one of the chicken brands. No brands exceeded the maximum residue limits.
