I purchased some hog casings from a butcher about a month ago. when I came home I put them in a container of freshwater with a top on it.I use some of the casings and I left some in the container. the ones that I left in the container I wash them before putting them back in there. now the water in the container is cloudy, the hog casings have a very strong smell. are my hog casings still usable? or should I throw my hog casings away? Thanks
