I haven't read much about this at all, so someone with more time than myself can research this, but... I know lots of fish food (ie, pellets fed to hatchery and farm-raised fish) contains chicken and other non-fish meat byproducts... if these prions can indeed withstand being eaten, processed, cooked, etc, there might be a POSSIBILITY that prions could be tranferred from cows to chickens (via the chickens' feed) and consequently from chickens to fish (via the fishes' feed)
