April 2, 2010 – CHICAGO (EWA) – 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, which was authored by Drs. Nicholas Dodman, Nicolas Blondeau and Ann M. Marini, 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.
