Question:
Is one allowed to cook/benefit from non-kosher meat from a kosher animal (regular meat slaughtered by a goy) with milk from a kosher animal? I read that the prohibition is only on kosher meat and kosher milk, but I am not sure if the meat has to be shechted or not in order for us to have basar b’chalav issues.
Answer:
The prohibition not to cook them together will apply, however the prohibition not to benefit from what was cooked is controversial, and in extenuating circumstances one may be lenient.
