As far back as 2008 Diclofenac,NSAIDS and the threat to Iberian vultures was a hot topic at the Iberia Nature Forum. It ran into many pages and had over 25,000 views in just a few weeks. This is the original post from back then with the links to the relevant articles at the time.
Diclofenac,NSAIDS and the threat to Iberian vultures
« on: May 02, 2008, 09:14 AM »
Reading the latest from the BBC about diclofenac and the Asian vulture population decimation it seems whilst there are people working really hard to help reduce the damage, the pharmaceutical companies are just selling the stuff as normal…http://news.bbc.co.uk/2/hi/science/nature/7373381.stm
With the news that Diclofenac is now available in Africa it won’t be long before we see problems with the Iberian migratory Griffons that cross the straits of Gibraltar every year… I still don’t have any estimated numbers of migrants passing this way and also I am under the impression that some griffons this far south in Andalucia make regular trips across to Morocco during the year depending on carrion food supply…
Here is the RSBP link: http://www.rspb.org.uk/news/details.asp?id=tcm:9-188408
And now diclofenac rears its ugly head again with the news that vultures are dying in Spain due to diclofenac poisoining. (Diclofenac was approved in Spain and other European nations in recent years because farmers, drug companies and regulators argued that cattle carcasses were disposed of differently in Europe than in India. This meant vultures would not be able to eat meat tainted with diclofenac).

Oh dear… It does seem that there is now a proven case of a Black vulture juvenile death caused by diclofenac…. (Last september) It has taken a long time for it to come into the mainstream press though.
The page at VCF has the better updated information: https://www.4vultures.org/first-evidence-of-a-vulture-killed-by-veterinary-diclofenac-in-spain/

The article on the birdlife website also has published information on this… It’s so sad to hear that this is still a problem when there are alternative drugs that do the same thing but don’t harm our wildlife

I found the original study that is linked from the articles previously mentioned. I dont have a member account though so can only see the abstract.
Diclofenac is a non-steroidal anti-inflammatory drug (NSAID) with a well-known toxicity for old world vultures that ingest the carrion of domestic animals treated with it. Diclofenac intoxication was directly related to the dramatic declines in the populations of three native South Asian Gyps vulture species two decades ago. In 2013, this NSAID was authorised for veterinary use in Spain, which has the largest vulture populations in Europe. One of these species is the cinereous vulture ( Aegypius monachus ), which is classified as “near threatened” by the International Union for Conservation of Nature (IUCN). This species has been reintroduced and monitored in Catalonia (NE Spain) since 2007, and in 2020 its current population consisted of 15 breeding pairs and a total number of 61 individuals. In September 2020, one fledgling was found dead in the nest. Post-mortem examination revealed severe generalised visceral and articular gout, which was confirmed histologically. Diclofenac was detected at average concentrations of 26.5 ng/g in the liver and 51.4 ng/g in kidney replicates (n = 3), respectively. These findings support a diagnosis of fatal gout caused by diclofenac intoxication. This is the first case of diclofenac poisoning in Spain (and in Europe), in addition to being the first report of diclofenac poisoning in cinereous vultures. This case report, therefore, supports the need to closely monitor vulture populations and carry out strict regulatory measures with which to prevent these poisonings.April 15, 2021 at 8:40 am #640Helen
It would seem that there have already been death’s from another steroidal drug called Flunixin. Halfway down on this page it clearly states that some vultures in Spain have died from it. https://www.4vultures.org/first-evidence-of-a-vulture-killed-by-veterinary-diclofenac-in-spain/
According to the data presented in the paper, veterinary diclofenac was detected at average concentrations of 26.5 ng/g in the liver and 51.4 ng/g in kidney replicates (n=3), respectively of this Cinereous Vulture. Before, researchers in Spain had already shown that veterinary diclofenac was present in 0,44% of carcasses sampled in supplementary feeding sites in Spain, suggesting it was a matter of time before the first intoxicated vulture would be found. Studies also found that about 1% of dead vultures sampled had Fluxinin residues in the liver or kidney. Fluxinin is also toxic to vultures, and several dead Griffon Vultures have already been killed by Flunixin poisoning in Spain.
Flunixin meglumine is a nonsteroidal anti-inflammatory drug (NSAID) and cyclooxygenase inhibitor. It is a potent analgesic, antipyretic, and anti-inflammatory. NSAIDs work by inhibiting the body’s production of prostaglandins and other chemicals that stimulate the body’s inflammatory response.

I posted this on your facebook post Clive but I thought it also useful here to inform the conversation:
I previously worked on this so it is something close to my heart / major concerns. The reason why it was licensed in the EU was it was concluded that animal husbandry was quite different to that of Asia where the problem was so acute and that as an anti-inflammatory it would be used much more sparingly therefore the EU went ahead and granted the licence, now we have this confirmed case (and there have been others suspected) then it should instigate a review of the licensing and hopefully a ban. Also diclofenac isn’t just about Vultures it will likely kill (or leave dangerous residue levels) other species such as Spanish Imperial Eagle too! Basically pretty much all carrion eating birds feeding on that one treated animal could likely die from renal failure! (or present dangerous levels of residues). The vast majority of Europes Vultures are found here in Spain so it we require an urgent review and hopefully subsequent removal of the licence and a ban. If the EU can do this for neonicotinoids from peer reviewed studies and impressively against fierce industry lobbying…..albeit it took until January 2020 some 5 years after the initial product reviews!
…In addition I think SEO / Birdlife international will need to take this opportunity along with other conservation agencies to intensely lobby for removal of the licence for diclofenac in Spain and across the EU. Given the vast majority of Europe’s Vultures are here in Spain then at the very least a removal from the use here…please!!

Be great if more people did that StraitsBirder 🙂 It’s like pulling teeth getting people away from facebook!
Thanks for the update but I fear the EU review on this vetinary product will be a long time coming….
