Just seen the thread and it seems she is being cautious
The example that CCC4 gave sounds like thats what would happen in theory if they got it. Oh, and if their owners have it wouldn't they have passed it onto their pigs who Vedra still treats? Or have I missed something? I could understand total exclusion of pigs and owners but if its zoonotic and the Human has it they will have passed it to the pig that is handed over the gate to Vedra to treat?
