Shaykh Ibn Uthaymeen was asked,

Question:

“What is the ruling on eating food which is cooked in something of pork fat?

Answer:

“It is not allowed to eat it. Whatever is changed by this fat, then it is impure and it makes the clothing, body, and vessels impure”. End translation. [‘Ilaam al-Musaafireen (pg. 92)]
