Yes, there is a slaughter house left in the City of St. Louis. Now known as Star Packing, it was once, based off of ghost signs also known as United Meat Co., among others. This was apparently, based off of Sanborn Maps, once sort of a meatpacking district one hundred years ago. It provides Kosher and Halal meat to many grocery stores and restaurants. Located on Cote Brilliante Avenue in between Vandeventer and Prairie Avenues in the JeffVanderLou neighborhood, it is now surrounded by a church, vacant lots and scrapyards.
