Smithfield’s plant in Monmouth, Illinois, is closed for an undetermined amount of time after a massive fire on Monday night.  The fire hit the rendering area of the plant but no one was injured.  Most of the workers were off for the Labor Day holiday and a cleaning crew inside the building was safely evacuated.  A Smithfield spokesperson said further assessments will be made this week and they’ll get the plant back up and running as soon as possible.  Firefighters from up to a dozen departments in the area responded to the blaze.  The plant employs up to 1,500 workers that produce fresh pork products and ready to cook bacon.
