Presence of some mycotoxins in feedstuffs in Bulgaria during 2017 | Presence of some mycotoxins in feedstuffs in Bulgaria during 2017

Bulgarian. Mycotoxins are secondary metabolites produced by fungi which can affect a variety of feedstuffs.These compounds elicit toxicological effects which represent risk for both humans and animals.This study aimed to investigate the presence of mycotoxins Zearalenone (ZEA), Ochratoxin A(OTA), Deoxinivalenol (DON), Aflatoxin, Fumonisin as natural contaminants of maize, wheat, barleyand sunflower.The samples were analyzed by Enzyme-linked immunosorbent assay – ELISA.A total number of 59 samples had been investigated.The content of DON for barley was estimated in the range between 0.544 and 2.29 mg/kg. Thecontamination with aflatoxin was between 2 and 14.49 µg/kg. The highest concentration was estimated in one sample of sunflower. More favorable substrate for Fumonisins accumulation was maize.The occurrence of ZEA varied from 51.65 μg/kg to 126.54 μg/kg in wheat and 48.67–79.64 µg/kg inbarley. OTA contamination was between 4.86–7.32 µg/kg in wheat and 4.46–11.70 µg/kg in barleyrespectively.These results suggest a high percentage of ZEA and OTA, especially in wheat and barley.
