The Centers for Disease Control and Prevention (CDC) is warning people across the U.S. not to eat romaine lettuce, citing an outbreak of E. coli.
The CDC said the broad warning is in place until it can gather more information.
According to the agency, 32 people in 11 states have been infected with E. coli so far. Thirteen people have been hospitalized, including one person who developed a type of kidney failure, but there have been no reported deaths.
The CDC is telling people to throw away any romaine lettuce that they already have in their homes.
Another outbreak of E. coli in romaine lettuce killed five people earlier this year.
