On Zev Brenner's radio show last night, Dr. Avraham Pollack of the Star K was asked for the Star K's position of Chabad shochtim, especially Chabad messianist shochtim. Would the Star K hire them? Approve their shechita?
Almost 100%, as close to certain as possible, we'd have to check every individual case, but…, it is not a hard and fast rule, however…, I can say with near certainty… It is not very likely we would approve or hire one.
I hope to have the actual quotes (which aren't much different from what I posted) and an mp3 of the exchange between Dr. Pollack and Rabbi Harry Cohen posted sometime today.
