When you say, "phlegm like texture," you actually are referring, literally, to faeces.
I don't think that's feces. Natural casings for sausages are made from small intestines; digested food doesn't turn to feces until it reaches the large intestine. The "phlegm" inside them is actually chyme ([pronounced: kahym], an anatomical term for digested food). If they're cleaned and cooked properly, they actually have a much better texture than plastic casings or no casings at all. Large intestines are usually disposed or incinerated; they're not safe to feed to animals, because well, they're full of crap. (This is not to be confused with pork butt, which is actually the pig equivalent of the gluteal muscle.)
