USDA's Office of Inspector General (OIG) visited very small plants in FSIS' Philadelphia District (Pennsylvania and New Jersey) recently to audit both how the plants are carrying out the HACCP regulation, and how FSIS, the regulatory agency is enforcing the regulation.  The OIG audit comes three years after a similar audit was carried out in large and small plants.  The Office of Inspector General has been quite critical of how FSIS verifies and enforces the HACCP regulations.  Last year, the watchdog agency strongly criticized FSIS inspection in large meat packing plants, particularly in Swift Co., formerly ConAgra in Greeley, CO.  FSIS answered OIG's criticisms defensively, pointing out it was already implementing suggestions OIG made.
