Study by Tufts University’s Cummings School of Veterinary Medicine finds significant rodenticide contamination in red-tailed hawks – News – telegram.com
GRAFTON – It has long been established that birds of prey have been ingesting poison from mice, rats and other small animals they catch, but the numbers may be on the increase, according to a study by Dr. Maureen Murray, a professor of wildlife medicine at Tufts University’s Cummings School of Veterinary Medicine.
Murray has been studying the impacts of rodenticide poisoning on hawks, owls and other birds of prey for more than a decade. In 2011 she published a paper showing the presence of anticoagulant rodenticides in 86% of birds tested over five years at Tufts. The study helped shape EPA safety standards that resulted in certain products being removed from the counters of home improvement and garden supply stores. Regulations that went into effect in 2011 were intended to prevent direct sales of ARs to the general public, limiting sales to rodent control professionals to use as needed.
