Abstract

Safe animal feed is important for the health of animals, the environment and for the safety of foods of animal origin. Therefore, the aims of this study were: 1) to validate simultaneous analytical method and 2) to investigate the amount of pesticide residues in animal feed from Republic of Korea as a part of official control. A total of 126 samples were collected in 2015 and analyzed for 105 pesticides. According to pesticides monitoring result, no residue was found in 84.1% of the samples, whereas 15.9% of samples contained pesticide residues below the maximum residue limits (MRLs). Pirimiphos-methyl and cyproconazole were the two most frequently found pesticides. The results show that all commercial feed monitored in 2015 were safe under the Korean MRL and occurrence of pesticide residues in animal feed could not be considered serious threats to human and animal health. However, continuous monitoring with tighter regulation for pesticide residues in animal feed is recommended.

사료의 안전성은 우리가 먹는 축산식품 및 그 가공품의 안전성과 직결된다. 따라서 이 연구의 목적은 1) 사료 중 관리대상 농약의 동시분석법을 확립하고, 2) 국내외 사료 중 농약 잔류실태를 조사하여 원료부터의 축산식품의 안전성을 확보하고자 하였다. 농약 잔류실태 조사를 위해 국내 유통 사료 126점을 수거하였고, 농약잔류허용기준이 설정된 농약 121성분 중 동시분석이 가능한 105성분에 대해 분석법을 확립한 후 농약 잔류실태를 조사하였다. 농약 잔류실태 조사 결과에 따르면, 126점의 사료 중 106점(84.1%)이 불검출이었고, 20점(15.9%)에서 7성분이 농약잔류허용기준 이내로 검출되었다. 검출빈도가 높은 농약으로는 각각 5점에서 검출된 pirimiphos-methyl과 cyproconazole이었다. 이 밖에도 propiconazole, azoxystrobin, tricyclazole 등이 검출되었다. 이 결과들은 2015년 국내 유통 사료가 잔류허용기준 이하로 안전하게 관리되고 있음을 보여준다. 그럼에도 불구하고, 사료의 안전성 강화 및 불량사료 원천차단을 위해 지속적인 잔류 실태조사가 필요하다.
