Animal welfare continues to be an important issue in the whole world. Therefore the
production of safe feed remains one of the most important tasks because the consumption of
contaminated feeds by livestock has been associated with a variety of adverse health effects
including feed refusal, reduced weight gain, diarrhoea and emesis. Wheat bran, a by-product
of the dry milling of common wheat (Triticum aestivum L.) into flour, is one of the major
agro-industrial by-products used in animal feeding. In addition, wheat bran can also been used
in human diet as a source of fiber in the preparation of high-fiber pasta, noodles etc.
Deoxynivalenol (DON) is one of several mycotoxins produced by certain Fusarium species
that frequently infect wheat, corn, rice, oats, barley and other grains in the field or during
storage. In this study, a total of 72 samples of wheat bran were collected from several
producers from Serbia in the period 2019-2020. The samples were analysed for
deoxyniva...lenol (DON) content by using an enzyme-linked immunosorbent assay
Ridascreen®
Fast DON SC. The occurrence of DON in the tested samples was 100%, with
average concentration 2.79 mg kg-1 and maximum DON content of 9.12 mg kg-1
. These
results suggest very high level of DON concentration in all tested samples. The limit of 8.00
mg kg-1 imposed by Serbian legislation for DON content in feed was exceeded in two studied
samples. However, only fourteen of them (19%) would be suitable for human consumption,
due to a much lower allowed limit (0.75 mg kg-1
), which raises a risk for consumers.
