The Grand Ayatollah Sistani’s Fatwa about Imported cheese from non-Muslim countries

Question: What about imported cheese from non-Muslim countries, if I do not exactly know the way it was made and its ingredients?

Question: Some of the cheese products manufactured in non-Muslim countries contain rennet extracted from the calf or other animals. We do not know whether the rennet was taken from the animal that was slaughtered according to Islamic laws; neither do we know that it has transformed into something else. So, is it permissible to eat such cheese?

Question: What is the ruling of the consumption of dairy products (e.g., milk, cheese, yoghurt, ice cream, etc) imported from non-Muslim countries, for example, China, India, etc, with the possibility of them being prepared by people of various faiths?
