I picked up some from cabelas today....I was dry heaving they smelled so bad..I phoned the number on the back and got winnipeg where they are packaged and the guy said it was normal and didn't know why..said his whole shop smelled when they get them in.
After spending a ton of time rinsing them I was able to get the smell out.. was very frustrating, they were incredibly hard to get started over the end of the horn..
I hate collagen casings and now I hate sheep casings..from now on if Im having homemade breakfeast sausages the will be hog casings..
