Minnesota health officials are warning consumers not to eat certain brands of alfalfa sprouts that have been tied to an unusual outbreak involving different disease-causing bacteria.

Officials say 23 people in Minnesota have become ill with either E. coli or salmonella infections, with two of them hospitalized.

Three had salmonella, and one of them also had a strain of E. coli bacteria called STEC O168:H8. Seven other people were sickened with a different version of E. coli, called STEC O103:H25. Thirteen more had yet another strain, STEC O26:H11.
