WASHINGTON (AP) — Sprouts from the sandwich chain Jimmy John’s have been linked to an outbreak of foodborne illness — again. The federal Centers for Disease Control and Prevention said Wednesday that 12 cases of E. coli poisoning in five states are linked to clover sprouts eaten at Jimmy John’s restaurants. The outbreak comes a year after sprouts from one of the chain’s suppliers were linked to 140 salmonella illnesses. Sprouts from the chain were also linked to a 2009 salmonella outbreak in several Midwestern states and were suspected in an E. coli outbreak in Colorado in 2008. The CDC reports more than 30 sprout outbreaks in the last 15 years. Sprouts need warm and humid conditions to grow, encouraging bacterial growth.
