U.S. health officials report an outbreak of foodborne illness linked to alfalfa sprouts causing infections with both E. coli and Salmonella. The Centers for Disease Control and Prevention (CDC) says it is aware of 55 cases nationally as of Friday, including four hospitalizations.

Officials say the illness has been identified across 15 states, based on state investigations. The Hill reports that CDC ties the outbreak to alfalfa sprouts sold under the Calco and Everything Sprouts brands and urges people who purchased affected products to discard them. Other outlets focus on the national case count and the involvement of both pathogens, reflecting differences in emphasis on either the scope of infections or the implicated brands.
