In all, 72 samples of raw materials for equine feed were collected from farms located in different parts of northern Italy, and the presence of deoxynivalenol (DON) and T-2 toxin was evaluated using enzyme-linked immunosorbent assay.

Abstract

In all, 72 samples of raw materials for equine feed were collected from farms located in different parts of northern Italy, and the presence of deoxynivalenol (DON) and T-2 toxin was evaluated using enzyme-linked immunosorbent assay. DON was detected in 38.9% of the samples tested, at levels ranging from 0.2 to 1.9 mg/kg. Maize was found to have the highest concentrations of DON, whereas barley was found to be the most commonly contaminated grain (73.3%). T-2 toxin was found in maize and rice bran at levels ranging from 12 to 102 μg/kg, with an overall incidence of 12.3% in the samples analyzed. In almost all the samples, T-2 toxin was found only in combination with DON. The occurrence of contamination observed in this survey, especially the presence of DON, is noteworthy. The levels detected are not very high, but even long-term exposure to low doses of these mycotoxins may represent a threat to horse health.
