Poor Cows

More than 850 cows have been 'marooned' for 2 months on a ship, the Karim Allah, stuck in Cartagena harbour, Spain (https://www.theguardian.com/world/2021/feb/27/cattle-stranded-on-ship-in-mediterranean-must-be-destroyed-say-vets). Nobody wanted to buy the cows, because it was suspected they might have Blue tongue, an insect-vectored disease of cattle. The animals are in such bad condition (several died and others are unaccounted for), that Spanish vets have ruled they are unfit for travel and must be humanely destroyed. The ship's owners are resisting this. I thought the rules on humane transport would be more strictly observed? It really doesn't set a good example.
