The latest survey compiles the results of more than 26,000 analyses to give an overview of the main threats caused by the six main agricultural relevant mycotoxin groups including aflatoxins (Afla), zearalenone (ZEN), deoxynivalenol (DON), T-2 toxin (T-2), fumonisins (FUM) and ochratoxin A (OTA).
Figure 1: Mycotoxin Risk Map
The mycotoxin risk map illustrates the mycotoxin occurrence data for each region as a percentage of all samples tested. The overall risk level for a particular region is determined by the number of single mycotoxins with average contamination levels (measured in parts per billion, ppb) which lie above the maximum risk threshold levels for livestock.
The risk thresholds are based on worldwide practical experience in the field and in scientific trials that were conducted to reflect as closely as possible field situations and take into account the most sensitive species for each mycotoxin.
- North America registered the highest average values for ZEN and FUM
- Europe recorded the highest average concentration of DON
- FUM remains the main threat in South America, as more than two thirds of all samples were contaminated
- Almost 80% of all North Asian samples were contaminated with DON
- Middle East registered the highest average OTA level at 13 ppb
- More than three quarters of all African samples contained ZEN
The analysis of the 6,844 samples in this survey clearly indicated that constant monitoring of mycotoxins is important. An effective mycotoxin risk management program is essential in order to protect animals from the negative impacts of mycotoxins on animals' health and performance.
