A peer reviewed scientific study tracing race horses sent to slaughter for human consumption has found that 100% of the horses in the study group had been administered phenylbutazone, a banned carcinogen that can also fatally damage the bone marrow of humans.
The findings appear to validate the European Union’s recent tightening of traceability requirements on horse meat from third countries.
The paper, titled Association of phenylbutazone usage with horses bought for slaughter: A public health risk , appeared in the journal Food and Chemical Toxicology and calls into question the reliability of the USDA (US Department of Agriculture) and CFIA (Canadian Food Inspection Agency) testing programs which have consistently failed to detect the substance.
The manuscript(1), which was authored by Drs. Nicholas Dodman(2), Nicolas Blondeau(3) and Ann M. Marini(4), followed eighteen Thoroughbred (TB) race horses that were identified by matching their registered name to their race track drug record over a five year period and were given phenylbutazone (PBZ, Bute) on race day and were subsequently sent to slaughter for human consumption.
The study also traced records on sixteen TB race horses that were given PBZ on race day and would have also entered the food chain had they not been rescued. The study was limited to race horses because of the availability of drug records, but phenylbutazone is one of the most common drugs used in the treatment of musculoskeletal injuries in horses.
Because of the bone marrow toxicity caused by PBZ in humans, the Food and Drug Administration (FDA) has set no safe levels of PBZ and bans its use food producing animals, including horses. While PBZ is but one of the numerous banned substances that are routinely given to US horses, it is one of the most dangerous. Read more >>
Interestingly, we have had reports that when veterinarians administer Bute to animals that may enter the food chain, they mention that they should not be slaughtered for human consumption. Yet, they have not issued the same warning when administering it to their horses. Hmmmmm.
