- Hello Jeff - It appears that almost every time I do a
Rense program, one of the ProMed moderators posts within an hour on a subject
I discussed on your program. This time it was the Bovine die off in Wisconsin.
Seems like the subject is "word for word" what I stated on your
program. Maybe I was not as specific as I could have been and the moderator
wants to be sure.
- I believe that Dr. Vanderloo is explaining the moldy
sweet potato poisoning and how they tested for it and basically what the
toxin does to cattle.
- TG is Tam Garland and he (a ProMed Moderator) has been
very helpful to me in the past as far as explaining to me various situations
whenever I have contacted him.
- The following should clear up any inconsistencies. Jeff,
I do believe that those in high places are listening to you very carefully...
- UNDIAGNOSED DIE-OFF, BOVINE - USA (02): (WISCONSIN)
- Date: 31 Jan 2010
- From: Peter Vanderloo Peter.Vanderloo@wvdl.wisc.edu
- [Although ProMED-mail has posted the diagnosis of this
bovine die-off, this particular post is from the diagnostic laboratory
having done the work and is a useful confirmation of the diagnosis. - Mod.TG]
- Subject: cause of death, steers in a Wisconsin feedlot
from mycotoxin in moldy sweet potato
- This post is a response to a request for information
regarding the cause of death of approximately 200 steers in a Portage
County, Wisconsin feedlot.
- In mid-January 2011, approximately 200 steers died in
a Portage County feedlot. Specimens from 2 animals were submitted
to the Wisconsin Veterinary Diagnostic Laboratory (WVDL) for testing.
- Results from testing at a referral laboratory identified
the presence of ipomeanol in the feed. This compound is a mycotoxin
present in moldy sweet potato. Sweet potato waste, not intended for
human consumption, was a significant component of the diet of the
steers at the time of the disease event.
- The major viral bovine pathogens of cattle (BHV1, BVDV,
BRSV, Corona virus) were not identified by PCR in the samples provided
to the WVDL. (When the deaths of the steers were 1st reported, there
was speculation that IBR/BVD was the cause of death.)
- Based on history, clinical signs, macroscopic and microscopic
changes in tissue, and test results from the WVDL and the referral
laboratory, it is very likely that mycotoxin from moldy sweet potato
was a major factor in the disease and death loss observed in the these

- ProMED-mail would like to thank Dr. Vanderloo for providing
details on the investigations and diagnostic studies performed on
this event. A thorough comment regarding the mycotoxin and the toxic
agent ipomeanol was posted in ProMED-mail Ipomeanol poisoning, fatal,
