The disinfectant and movement stoppage does not prevent the airborne infection, which is precisely what makes the disease so hard to control. The temperatures reached by the burning pyres are sufficient to kill the virus.

The key word in BanjoRay's comparison with '67 is "quickly". This time slaughtered animals have been left rotting for days before the carcasses are disposed of. Largely because MAFF refused to admit the problem was out of control. There weren't enough vets to diagnose the disease, there weren't enough slaughtermen to deal with the diagnosed beasts, and the army should have been used right from the beginning to coordinate the disposal of the carcasses.
