The sign says they have arranged mehudar milk with no concern of shmitta issues? what shmitta issues might there be with milk? The cows might have been fed grains or grasses that were affected by shmitta. They, whiever they are, have arranged the milking of cows who were only fed grains and produce harvested in the sixth year, clear of any shmitta concerns so the milk they produced is also clear of shmitta concerns. Additionally the cows have not had surgical procedures done on them to minimize any concern of treifas.

I have never heard of this chumra before, and this is my fourth shmitta cycle in Israel. Ar first I thought it might be a joke, but I am told it is not.
