You really missed the point. The source of the Sakana is not from Chazal. It is from the 14th century doctors. There is no reason that I have to take their musings into consideration.
If we were to worry about what every doctor of every period worried about we would be down to nothing.
It is kept out of reverence, but to say that it can’t be Battul B’rov is really going out on a limb.
