Thought I would share this..... I made these snack sticks 3 weeks ago and they were wrapped in foil and in the refrigerator. This is what I usually see at about three weeks. You can see where white mold is starting to form and some furry stuff...not good. If this sausage was vacuum sealed this would start to occur at about 1.5 months in the fridge. You wouldn't be able to see it but the sausage would get slimy and when you cooked it and it dried, the white speckle on the casings would become visible......
