Occurrence of mycotoxins in feed samples in Burdur Province, Turkey.

The aim of this study was to evaluate the incidence of total aflatoxin (AF), ochratoxin A, T-2 toxin, deoxynivalenol (DON), zearalenone (ZEA), and fumonisin (FB) in dairy cattle, beef cattle, and lamb-calf feeds. A total of 180 dairy cattle, beef cattle, and lamb-calf feeds (60 samples each) were randomly collected from farms, feed mills, and villages in Burdur province, between September 2006 and August 2007. All samples were analyzed by the competitive Enzyme Linked Immuno Sorbent Assay (ELISA). The most frequent mycotoxin detected was total AF, which was found in 108 samples (60 %) in concentrations ranging from 3.82 to 116.83 μg kg(-1), followed by DON that was detected in 87 samples (48.3 %), in concentrations ranging from 18.50 to 500 μg kg(-1). Ochratoxin A (OTA), T-2 toxin, ZEA, and FB were found in 84 (46.7 %), 85 (47.2 %), 57 (31.7 %), and 19 (10.6 %) samples, respectively, in concentrations of 1.01 to 15.85 μg kg(-1) for OTA, 3.85 to 52.36 μg kg(-1) for T-2 toxin, 2.10 to 29.30 μg kg(-1) for ZEA, and 2.69 to 4.96 mg kg(-1) for FB. It was concluded that feed samples in Burdur province were contaminated by mycotoxins, and the levels of total aflatoxin in the samples were considered a risk to animal health.
