Survey of mycotoxin feed contamination in Croatia

The aim of this study was to investigate the contamination of feed with mycotoxins. A total of 103 samples of feed for poultry, pig and calves was collected at different animal feed factories in the central, eastern and north region of Croatia. The quantitative determination of aflatoxin B1 (AFB1), ochratoxin A (OTA), zearalenone (ZEA), deoxynivalenol (DON), fumonisins B1, B2 and B3 (FUM) and T-2 toxin (T-2) concentration was done using the validated ELISA method. The observed results indicated an increased contamination of pig feed with Fusarium mycotoxins DON and ZEA with mean concentrations of 1454±1444 μg/kg and 153±161 μg/kg, higher than recommended in 20% and 5% of the samples, respectively. Higher DON concentrations than recommended were also observed in 7% of calves feed with a mean concentration of 1140±1288 μg/kg. The concentrations of AFB1, OTA and FUM in all the investigated samples in all country regions were according to the maximum allowed or recommended values in the European Union.
