The U.S. Food and Drug Administration and the Centers for Disease Control and Prevention told people on Sunday not to eat raw alfalfa sprouts, saying they may be contaminated with salmonella.
The contamination appears to be in seeds so washing the sprouts may not help, the FDA said in a statement.
"Other types of sprouts have not been implicated at this time," the agency said.
"FDA will work with the alfalfa sprout industry to help identify which seeds and alfalfa sprouts are not connected with this contamination, so that this advisory can be changed as quickly as possible."
