[Avodah] kashrus of milk

[Rich, Joel]

But why would we hold of anything but rov? It's not a question of bitul
betaaroves, but of birur safeiq deleisa leqaman. (Given that qasheh
levarer makes a safeiq "leisa leqaman".)

Tir'u baTov!

========================================
I am having a hard time tieing together all the concepts.

where do we find the concept of qasheh levarer at all or that it has the
power to make a safeiq leita leqaman? I could not find any rishonim who
mentioned it (but of course that's not a rayah:-))


What if we "knew" one cow was treif in the herd of 50 cows after they
had all been milked into the same vat but before the milk was used.
Would we say rov is enough or require shishim?
