eeewww, that's yucky.
Mince and sausages aren't like a steak - they have been handled more and exposed to more germs. I would never want a pink sausage The texture would be all wrong. I made a sausage casserole once in the slow cooker and it tasted fine but I couldn't eat it all because the texture of the sausage made my stomach turn.
There is bacteria on the surface of all meat but your solid piece of steak will only have it on the outside.
Rissoles and snags contain more bacteria because the insides have been exposed to the air during the manufacturing process so they need to be cooked all the way through.
