    Occurrence of aflatoxin b1 and t-2 toxin in feed and raw ingredients used for animal feeding stuffs
    (Uludağ Üniversitesi, 2007-02-19) Oruç, H. Hüseyin; Cengiz, Murat; Uzunoğlu, İlknur; Uludağ Üniversitesi/Veteriner Fakültesi.; Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü.
    Examination of 93 samples of animal feed and feed ingredients for the presence of aflatoxin B1 (AFB1) and T-2 toxin has been carried out. These samples were collected from four feed mills and 17 farmers of milk producer in Bursa region, Turkey, and analyzed by competitive enzyme-linked immunoabsorbent assay (ELISA) technique. AFB1 and T-2 toxin were determined in all samples of dairy cattle feed (except one of them for T-2 toxin), fattening feed, fawn feed, broiler feed, rice bran, rice grain, barley-wheat grain, maize and dry distiller grain soluble (DDGS), soya meal and sunflower meal. The highest levels detected for AFB1 and T-2 toxin were 431.90 µg/kg in a sample of maize and 131.00 µg/kg in a sample of rice bran, respectively. The mean levels of AFB1 have shown that the feeds and raw ingredients of samples may lead to some toxic effects for beef cattle, broiler, fawn, dairy cattle, and human because of the conversion of AFB1 in dairy cattle feed and feedstuffs to aflatoxin M1, and aflatoxin M1 secrete into milk.

    Ochratoxin a levels in different types of bread and flour
    (Uludağ Üniversitesi, 2007-02-19) Cengiz, Murat; Oruç, H. Hüseyin; Uzunoğlu, İlknur; Sonal, Songül; Uludağ Üniversitesi/Veteriner Fakültesi.; Uludağ Üniversitesi/Sağlık Bilimleri Enstitüsü.
    Ochratoxin A (OTA) levels were determined in 132 different types of flour and bread (34 white flour, 14 wholemeal flour, 10 corn flour, 36 white bread, 28 wholemeal bread and 10 corn breads). The samples were collected from different bakers and markets in Bursa, Turkey and some unities of Turkish Army between February 2005 and May 2006 for analyses. OTA concentrations were determined by competitive enzyme-linked immunoabsorbent assay (ELISA) technique. Among the samples, highest mean concentration was detected in wholemeal flour samples as 9.30 µg/kg. OTA has been determined in 110 samples (83%). In 92 (70 %) of the samples the toxin levels were exceeded maximum tolerable limits (3 µg/kg). These findings indicate that flour and breads may have potential risk for the public health.
