In general, I do not worry about weeds from worm castings. If you are worried about it, id go with the heat suggestion, or you could also let them rot/ferment in a barrel of unaerated water, then dump all that over the worm bin when it could use the moisture. You could also sprout them on a tarp or in aerated water then dump onto the bin for the worms to eat.
This is all just my opinion based on a flawed memory
