That sounds like a great opportunity to spread the resistant parasites from hive to hive and region to region.
Fishing vessels are spreading parasites at hyper-accelerated speeds. This happens when they clean the guts of infected fish at sea without prior treatment and when they discard untargeted fish in the same way; The parasites disperse exponentially, within a loop, when such parasitised food spreads through the trophic. This has already happened on a planetary level.
Also, to note, I think that if they start droping frozen guts into the sea as a treatment, our main defensive barrier at home (to froze fish some days before consumption) will eventually disappear when the parasites adapt (ie. not freezing them long enough until they die due neglect, would progressively disperse freeze-resistant strains in the wild).
I thought the main barier is to apply intense heat to the fish, not to freeze it.
