Critically endangered vultures in India are still at risk of exposure to the anti-inflammatory drug diclofenac, through widespread illegal sales of the drug.
The Indian government banned use of the drug for veterinary purposes in 2006 after it brought vultures to the brink of extinction. Vultures were being poisoned after eating the carcasses of cattle that had been treated with the drug. The manufacture of diclofenac for human purposes is still allowed.
