HOUSTON, (Horseback) – A second term state representative from a rural village who claims to represent the entire horse industry has challenged a peer reviewed article in a distinguished scientific journal citing a letter from three agricultural school equine science professors.
Rep. Sue Wallis (R) of Recluse, WY (pop 13), is the nation’s most outspoken proponent of reopening U.S. horse slaughter plants, shut down after Congress refused to fund federal meat inspectors in such facilities, and the U.S. Supreme Court refused to hear challenges to state laws in Texas and Illinois outlawing them.
The paper titled, “Association of phenylbutazone (Bute) usage with horses bought for slaughter”: a public health risk states in its abstract:
“Sixty-seven million pounds of horsemeat derived from American horses were sent abroad for human consumption last year. Horses are not raised as food animals in the United States, and mechanisms to ensure the removal of horses treated with banned substances from the food chain are inadequate at best. Phenylbutazone (PBZ) is the most commonly used
non-steroidal anti-inflammatory drug (NSAID) in equine practice. Thoroughbred (TB) race horses like other horse breeds are slaughtered for human consumption. Phenylbutazone is banned for use in any animal intended for human consumption because it causes serious and lethal idiosyncratic adverse effects in humans. The number of horses that have received phenylbutazone prior to being sent to slaughter for human consumption is unknown but its presence in some is highly likely. We identified eighteen TB race horses that were given PBZ on race day and sent for intended slaughter by matching their registered name to their race track drug record over a five year period. Sixteen rescued TB race horses were given PBZ on race day. Thus, PBZ residues may be present in some horsemeat derived from American horses. The permissive allowance of such horsemeat used for human consumption poses a serious public health risk.”
Wallis, in a press release cited a letter to the article’s publisher,
Food and Chemical Toxicology by four agricultural school professors challenging the findings of its authors, Drs.
Nicolas Dodman, a veterinary anesthesiologist at Tufts University, Nicolas Blondeau, The Institute of Molecular and Cellular Pharmacology (France), and Ann Marini, MD, PhD, of the Department of Neurology, Uniformed University of the Health Sciences.
The three experts changing the findings of Dodman, Blondeau, and Marini, are William Day, PhD of Morristown State College, Sheryl King PhD, PAS, of Southern Illinois State University, Don Henneke, PhD of Tarlton State University, and Pat Evans EdD of Scottsdale Community College. All are equine science instructors with no medical or veterinary training.
Marini was unavailable for comment.
The study’s critic also wrote a lengthy note to Congress blasting the study failed to mention that bute is prohibited by the federal Food and Drug Administration for use in all food animals.
Asked by
Horseback Online how the three United Horsemen experts could challenge the paper with no medical training, Wallis replied, “By that reasoning the original article authors weren’t qualified to write it.”
Horseback then asked Wallis, “Why does England and the rest of Europe require horse passports and only horses raised for their meat enter the food chain for human consumption?”
There has been no response.
“They really cherry picked their facts,” said John Holland, president of the Chicago Based Equine Welfare Alliance which completed a three day Washington D.C. conference last week featuring some of the nation’s top equine welfare scientists, academics, and advocates including Dr. Marini.
“For example, they stated that ninety percent of PBZ disappears from the blood in just over a day,” Holland said. “They neglected to mention its metabolite oxyphenylbutazone which is just as dangerous and lasts much longer.”
More recently in an Irish veterinary journal, the metabolite issue is addressed as well.
“Sue’s experts also omitted the fact that PBZ takes up in injured tissue,” Holland said in a written response to Horseback Online. “And then they cited an industry recommendation that was never adopted as if it had some special credibility: The 2004 Proceedings of The United States Pharmacopeial Convention reported that evidence had been compiled by the Canadian FARAD leading to the recommendation of a withdrawal time of 60 days following administration of phenylbutazone paste to beef animals and a withholding time of 10 days in milk would be sufficient to avoid residues.”
Holland countered misrepresentation saying, “they claimed I am ‘associated with HSUS and linked to PETA.’ I have no linkage to PETA what-so-ever, and only a loose association with HSUS (as if that were a crime).”
“They ignored the standing rule that PBZ is banned in all meat animals with no withdrawal period and that it is only allowed in diary animals under six months of age in a few countries. In other words, they are trying to spin things to create doubt where there really isn’t any,” Holland said.
