Carbofuran once killed up to 2 million birds each year , accord to the EPA . The pellet physical body of the pesticide , which calculate like metric grain seeds , was ban in the mid-1990s , when bald eagles were still on theendangered coinage list .
Even though it ’s banned , farmers appear to be using the pesticide as a style to belt down beast that eat plants ( such as illegally maturate marijuana ) and farm animal , The Washington Post reported . When these animals feed it , " it ’s a pretty ugly way of life to expire , " Bischoff tell The Washington Post . If ingested or inhale , it can make musculus cramps , excessive salivation , dizziness , puking , labored respiration and even unconsciousness , according to the Centers for Disease Control and Prevention . It can also prompt the glands in the lungs to secrete fluids , so that peril animate being " swim in their own fluids , " Bischoff said .
As a part of the probe , the Fish and Wildlife Service did necropsies ( creature autopsies ) on six of the 13 eagle , as well as a drained raccoon ( Procyon lotor ) found nearby . All six snort had carbofuran in their stomachs or crops , and the racoon tested positive as well .
It ’s potential that one of the bald eagles picked up the raccoon elsewhere and carry it to the farm in Federalsburg , where the other birds dined on the baneful repast , LaCorte told The Washington Post .
