Mycrobiological and Mycotoxicological Safety of the Feed in Braničevo and Podunavski Regions

Abstract

During 2007, 109 specimens of different feeds and their components, were bacteriologically, mycologically (on a number of the mildews) and mycotoxicologically examined. The examined specimens were from the Braničevo and Podunavski region in Serbia. For the interpretation of our examination results "Regulation of maximal quantity of harmful substances and components in the feed" (Governmental newspaper of SFRY, no. 2/90 and 27/90, paragraphs: 8, 9 and 11) was used. The correlations between the numbers of mildews and the concentrations of mycotoxins in the specimens also examined. The established number of bacteria and mildew was in the permitted level in all examined specimens. Pathogenic bacteria were isolated neither in one specimen. In 40 specimens presence and concentrations of Ochratoxin A, total Aflatoxin, Zearalenon and T-2 toxin were examined. Ochratoxin was established in 4 specimens (4%), total Aflatoxin in 27 specimens (67.5%), Zearalenon in 38 specimens (95%) and T-2 toxin in all examined specimens (100%). In most of the examined specimens two, three or all four mycotoxins were presented. Concentrations of mycotoxines were in permitted levels, except concentration of Zearalenon in one specimen. Coefficients of linear correlations between numbers of mildews and concentrations of mycotoxins in specimens were very low.
