Why is mycotoxicosis so difficult to detect? Geof Smith, DVM, PhD, Dipl. ACVIM, North Carolina State University, says there are a variety of reasons:

  • Mycotoxin "hot spots" in TMR samples or hay bales that may or may not get included in a sample.
  • Mycotoxicosis has non-specific symptoms, i.e. drop in milk production.
  • There are interactions with other mycotoxins/stress/disease
  • Lack of research with specific mycotoxins
  • Species differences.
  • Lack of feed samples.
  • Difficulties in gathering accurate samples.
  • Extensive and complex testing methods.

Smith spoke about mycotoxins in cattle at the Dr. Jack Walther 85th Annual Western Veterinary Conference this week in Las Vegas.
