Collaborative investigative efforts of state, local, and federal public health and regulatory agencies indicated that ground beef produced by Jouni Meats, Inc. and Gab Halal Foods are likely sources of this outbreak.  Seven of the ill persons reported eating a raw ground beef dish at the same restaurant before becoming ill. The restaurant served raw beef to customers and had acquired the raw beef from two retailers.
