1 st WorkshopXIII International Feed Technology Symposium102A SURVEY OF OCCURRENCE OF TOXIGENIC FUNGI ANDMYCOTOXINS IN PIG FEED SAMPLES FROM DIFFERENTPRODUCTION AREAS IN SERBIADragan Milićević 1 , Miomir Nikšić 2 , Verica Jurić 3 , Danijela Vranić 1 , SrđanStefanović 1i Institute of meat hygiene and technology, Kaćanskog 13, 11000 Belgrad, Serbia2 University of Belgrade, Faculty of Agriculture, Institute of Food Technology andBiochemistry, Nemanjina 6, 11080 Zemun, Serbia3 University of Novi Sad, Faculty of Agriculture, Department for Animal Sciences, TrgDositeja Obradovića 10, 21000 Novi Sad, SerbiaABSTRACTIt is considered that human and animals are permanently exposed to effects of variousmycotoxins at the time, usually at low concentration. Therefore, the aim of the presentwork was to evaluate the contamination of pig feed samples, taken from differentproduction areas in Serbia, by aflatoxins (AFT), ochratoxin A (OTA), deoxynivalenol(DON) and zearalenone (ZEA). Moreover, we focused on the contamination of pig feedsamples by the associated toxigenic fungi and influence of environmental factors such asmoisture content (%) and water availability (aw) on both the growth and mycotoxinsproduction. The results showed that majority of samples were contaminated by the twomycotoxins. The ochratoxin A (OTA) and deoxinivalenol (DON) was detected in 50 and55% of examined samples, respectively, while zearalenon (ZEA) was found in 44,4% ofsamples originating from investigated regions. Presence of aflatoxin was not found. Theaverage concentrations of mycotoxins in complete feedmixes were: OTA-0,06 mg/kg,DON-0,78 mg/kg while the average ZEA content was 0,85 mg/kg. Total mould count(CFU/g) in three samples of complete feedmixes was up to 10 5 , in nine samples it wasaround 10 5 -10 6 , while in six samples, level of contamination from moulds was higherthan 10 6 . During a mycological analysis of complete feedmixes intended for fatteningswine, a total of six genera and 14 species of moulds were identified. The main isolatedfungi belong to the genus Penicillium (94,4%) while the moulds from Fusarium andPaecilomyces genera isolated in 55,5% and 44,4% of the samples from investigatedlocalities, respectively. Other fungi from the genera Aspergillus (22%), Mycor (11,1%)and Alternaria (5,5%) were represented in a less amount.Key words: pig, feed, moulds, mycotoxinsINTRODUCTIONThe contamination of agricultural commodities with fungi able to produce toxicmetabolites is one of the main worldwide concerns. Discoloration, quality deterioration,reduction in commercial value and mycotoxin production has been linked to mouldycontaminated foods and feeds. It not only generates great economic losses [10], but alsorepresents a threat to human and animal health, particularly through the synthesis of
