Abstract

Nivalenol (NIV), deoxynivalenol (DON), T-2 toxin (T-2) and zearalenone (ZEN) are mycotoxins produced by some Fusarium species known to be very frequently contaminated in feed. The study for simultaneous analysis and contamination survey in animal feed carried out. All mycotoxins were analysed by using high performance liquid chromatography tandem mass with internal standard. The limits of detection (LOD) were $2.0\;{\mu}g/kg$, $1.0\;{\mu}g/kg$, $1.0\;{\mu}g/kg$ and $0.1\;{\mu}g/kg$ for NIV, DON, T-2 and ZEN, respectively. Two hundred and thirty nine samples of feed were collected. The average concentration of DON was $212.3\;{\mu}g/kg$, $207.8\;{\mu}g/kg$ and $812.1\;{\mu}g/kg$ in chicken, pig and cattle feed, respectively. The average concentration of ZEN was $31.2\;{\mu}g/kg$, $35.6\;{\mu}g/kg$ and $147.2\;{\mu}g/kg$ for them, respectively. Especially, the levels of contamination for DON and ZEN were higher than those of NIV or T-2. And, the levels of contamination for four Fusarium mycotoxins in cattle feed appeared higher than those of pig and chicken feed. It was investigated that the high level of mycotoxin contamination in cattle feed was caused by com gluten feed of ingredients for feed, mainly.

국내 유통사료 239점에 대하여 푸사리움 속 곰팡이독소 4종(NIV, DON, T-2, ZEN)에 대하여 오염도조사를 실시하였다. 일반적으로 곰팡이독소 정제에 많이 사용되는 면역친화 컬럼을 사용하지 않고 일반 SPE컬럼을 이용하였으며, HPLC/MS/MS로 동시 분석하였다. 각각의 성분 별로 77.42~111.20%의 회수율과 $0.3{\sim}2.0\;{\mu}g/l$의 양호한 정성한계(LOD)를 보였다. 분석 결과 사료 중에 조사대상 곰팡이독소가 광범위하게 오염되어 있었으며, 특히 DON과 ZEN은 모든 배합에서 확인되었다. 소 사료의 경우 DON과 ZEN은 평균 $812.1\;{\mu}g/kg$과 $147.2\;{\mu}g/kg$의 오염도를 보여 닭 사료나 돼지 사료보다 약 4배정도 높은 오염도를 보였으며, 그 원료로 사용된 단미 사료를 조사해본 결과 수입 단백피가 주요 오염원인 것으로 확인됐다.
