Bizjournal reports, ConAgra will complete the shutdown of its Garner Slim Jim production plant and lay off the remaining 394 employees there by May 27 – nearly two years after a fatal explosion at the facility. Some 234 of the layoffs will take place by April 16, according to a letter sent by ConAgra to the North Carolina Department of Commerce in accordance with the Worker Adjustment and Retaining Notification Act. The remaining 160 employees at the plant will lose their jobs no later than May 27, which is the day the plant''s permanent closure will take effect, says a company spokesman. The ConAgra plant was the only place where Slim Jim beef jerky snacks were made. About 750 people worked at the facility until an explosion sparked by a natural gas line repair in June 2009 ripped a hole in the plant’s roof and caused a large wall to collapse. In addition to killing four people, the blast injured dozens of others and forced ConAgra to shut down the plant for repairs.
