Van Havzasında Üretilen Çeşitli Karma Yemlerin Aflatoksin İçeriklerinin Araştırılması

Öz

Bu çalışmada, hayvan yemlerinde aflatoksinlerden B1, B2, G1 ve G2 araştırılmıştır. Van ilindeki 5 ayrı fabrikada üretilen yemlerden 3 farklı zamanda örnekler alınmış ve Shimadzu Prominence HPLC ile aflatoksinler belirlenmiştir. Her üç dönemde de analiz edilen toplam 48 yem örneğinde sırasıyla %67’sinde 0.12-4.74 µg/kg AFB1; %44’ünde 0.01-4.27 µg/kg AFB2; %4’ünde 0.11-0.52 µg/kg AFG1 ve %40’ında 0.14-10.30 µg/kg AFG2 saptanmıştır. Van havzasında elde edilen sonuçların kabul edilen üst sınır değerlerinin altında olduğu ve risk teşkil etmediği görülmüştür. Ancak yemlerin halen %67’sinin aflatoksinlerle bulaşık olduğu saptanmıştır

Investigation of Aflatoxin in the Completed Feed that Produced in the Van Basin

Abstract

In this study; it has been investigated that aflatoxins B1, B2, G1, G2 in the completed animal feed produce in the manufactures located in the Van basin. Feed samples were collected from 5 different commercial feed manufactures at the three different time and aflatoxins were analyzed by Shimadzu Prominence HPLC. The results showed that 67% rate of feed samples were contamined with AFB1 0.12-4.74 µg kg^-1; 44% rate of feed 0.01-4.27 µg kg^-1 AFB2; 4% rate of feed 0.11-0.52 µg kg^-1 AFG1 and 40% 0.14-10.30 µg kg^-1AFG2 respectively. It has been showed that obtained results of aflatoxin levels in the completed animal feed were lower than acceptable upper limit and were not at the risk level in the Van Basin. However it has been determined that there is still 67% of feed were contamineted with aflatoxins.
