diclofenac (NSAID) in carrion

Rhys E. Green et al (2006) report in Journal of applied ecology 43: 949-956 their study of asian vultures exposed to diclofenac (a non-steroidal anti-inflammatory drug) through veterinary use*

Bos indicus and Bos taurus cattle were injected with diclofenac; concentrations in the tissues decline rapidly, but the authors claim enough remains to cause >10% mortality among vultures "if birds were to take a large meal from the carcass". Diclofenac concentrations in fat, kidney and liver were "considerably higher than those in muscle". Three species of south asian vultures (Gyps bengalensis, Gyps indicus and Gyps tenuirostris) are said to have been in rapid decline and are critically endangered.
