(WHAS11) -- Sprouts used by the restaurant chain Jimmy John's have been linked to another outbreak of a food borne illness.
The Center for Disease Control reports 12 cases of e-coli in five states - all linked to clover sprouts used on Jimmy John’s sandwiches.
Illnesses have been reported in Iowa, Missouri, Kansas, Arkansas and Wisconsin.
The outbreak comes a year after sprouts were linked to 140 cases of salmonella. The sprouts were also linked to a salmonella outbreak in 2009 and suspected in another outbreak in 2008.
Sprouts need warm and humid conditions to grow which can encourage bacterial growth.
