Aflatoksin ve Okratoksin A ile Kontamine Olmuş Besi ve Süt Sığırı Yemlerinin Türkiye’deki Bölgesel Dağılımı

Bu çalışmanın amacı, besi ve süt sığırı yemlerinde aflatoksin AF ve okratoksin A OTA içerikleri ve bunların kimyasal kompozisyonları ile aralarındaki korelasyonu belirlemedir. Bunun için, 82 ticari yem örneği 2006 yılının sonbahar döneminde Türkiye’nin 5 farklı coğrafik bölgesinden toplanmıştır. Yemlerdeki AF ve OTA analizleri HPLC, besin madde içerikleri ise kimyasal yöntemlerle yapılmıştır. En yüksek ve en düşük AF içerikleri sırasıyla Akdeniz 7.51 µg/kg ve Ege 0.34 µg/kg bölgelerinde gözlemlenmiştir P

Regional Distribution of Aflatoxin and Ochratoxin A Contaminated Beef and Dairy Cattle Feeds in Turkey

The objectives of this study were to determine the aflatoxin AF and ochratoxin OTA contents and their correlations with chemical constituents of beef and dairy cattle feeds. Eighty-two commercial feed samples were collected from five different geographical regions of Turkey during fall season of 2006. The AF and OTA analyses were performed in HPLC while chemical constituents were determined with wet-chemistry. The highest and the lowest total AF contents were observed in Mediterranean 7.51 µg/kg and Aegean 0.34 µg/kg regions, respectively P
