I had asked a question regarding sausages and was given the below as a reply: "Sausages: they are Haram unless you are sure they are from a halal slaughtered meat, or you bought them from a Muslim market. If it is a packed product not produced by a Muslim you can’t trust the Halal sign unless you know the people involved in the Halal sign team and they have told you personally it is Halal, and the people in the team are trustworthy Muslims themselves."
