Conclusion
Multiple mycotoxins are frequently found in the forage eaten by horses
with increased liver enzymes. Emerging mycotoxins were most commonly
identified, type B trichothecenes were most commonly detected at levels
that could be a risk to equine health. Nearly half of samples had one or
more mycotoxins groups that were detected at a concentration that was
‘medium’ or ‘higher’ risk to animal health. The effects of mycotoxins in
horses and synergistic effects of multiple mycotoxins in horses warrant
further investigation.
