Mycological and mycotoxicological analysis of many feeding stuffs and complete mashes for different animal species and categories have shown that the feed safety problem has been present for years. It is approved that mouldy feed can contain various mycotoxins, but among them in our conditions the most investigated are aflatoxins, ochratoxins, zearalenone and some trichotecenes. Based on laboratory feed inspection of 107 samples of feed for pigs, 55 samples of feed for fattening swine and 46 samples of feed for swine for reproduction, sent to be analysed in the Institute of Veterinary Medicine of Serbia in Belgrade, it was concluded that fungi and mycotoxins contamination are common. Primarly presence of zearalenone, ochratoxine and aflatoxin was proven. Although these levels usually do not exceed limits layed by actual legislation, having on mind cumulative effects and possibal chronical exposure of animals to their harmful influence, appropriate and competent approach is necessary. In fact, even when direct loses, as concequence of high mortality are not present, indirect loses due to drop of animal performances and production and occurence of secondary infections must not be neglected.
