Had to share this article I read in the Jerusalem Post about whether casings for Kosher Hot Dogs are indeed Kosher. When I read that casings may be made from reconstituted collagen casings, produced from chemically treated animal skin including pig skin. The kicker is that lawsuits are already pending from a religious Jew and Muslim on the grounds they were mislead about the 'kosherness' of the hot dog. No comment from officials at Hebrew National.
Is a Kosher Hot Dog Kosher?
