The federal government says that a meat company based out of Georgia has recalled tons of ground beef, for a possible contamination of E. coli bacteria.  The bacteria is an unusual strain that has sickened 156 people in 10 different states, hospitalizing 20 of them.  Ground beef had been described as the likely source; however, officials say that they are still testing to see whether the recalled beef is related to the outbreak.  A recall notice from the US Department of Agriculture’s Food Safety Inspection Service, says that K2D Foods is recalling around 56.7 tons, or around 51.4 metric tons, of meat.  K2D does business as Colorado Premium Foods of Carrollton, Georgia, with the meat in 48-pound boxes, labeled as ground beef puck for institutional use.  Calls to the company’s headquarters in Greeley, Colorado, were not immediately returned.
