最近在西班牙發現有近危禿鷲因雙氯芬酸鈉死亡。雙氯芬酸鈉是畜牧業廣泛使用的止痛藥。禿鷲會因食用家畜屍體而直接吸收雙氯芬酸鈉，引致腎衰竭死亡。大部分亞洲地區已禁止使用此藥物，但西班牙及義大利因稱會妥善處理所以仍能合法使用。

an endangered cinereous vulture was found killed by diclofenac in Spain recently. Diclofenac is a common pain relieve drug for livestocks. If a vulture ate carcasses of cattle treated with this drug, it will damage its kidney and cause death. Diclofenac has been banned in most Asian regions, but is still legal in Spain and Italy as their farmers and regulators claim to  dispose cattle carcasses properly.
