"PZP / ZonaStat-H was touted by its manufacturer as "so safe it is boring" [11] and its contraceptive effects, as reversible. Relying on the manufacturer's representations, HSUS applied to the Environmental Protection Administration (EPA) to have the product approved for use on wild horses and burros, which the EPA did -- as a pesticide in cases where mustangs were deemed to have become a "nuisance,"' explains Marybeth Devlin in her detailed comments to BLM. Devlin continues, "So highly respected was HSUS' reputation, that EPA waived certain protocols that are normally required. Unfortunately, HSUS failed to fully investigate the product beforehand, has not done so subsequently, and does not seem interested in knowing about any drawbacks to its use. Consequently, HSUS is ignorant of the body of science weighing against PZP."

Devlin continues, "Now, HSUS is seeking to conduct a study of PZP on the subject herd of wild burros. But because HSUS is the registrant of the pesticide PZP, a conflict of interest is apparent. HSUS has a stake in the outcome of the proposed study, namely, to see it succeed and to ignore ill effects. Lacking scientific impartiality, HSUS must be disqualified from studying its sponsored product and from using taxpayer money to experiment on America's underpopulated wild burros."
