It should be clear that as muslims, we ought to avoid to eat meat or food prepared in the oil in which pork or haram food was fried/prepared. We should be careful to eat what is halal and pure and stay away from doubtful and haram food.
In this regard, Sheikh Ahmad Kutty, a senior lecturer and an Islamic scholar at the Islamic Institute of Toronto, Ontario, Canada, states: “A Muslim is not allowed to eat meat or food prepared in the oil in which pork was fried, because such oil contains ingredients from pork or at least has contact with pork, which is considered najas and impure.”
