Alfalfa sprouts recalled because of salmonella poisoning were sold to more than 400 Wal-Mart stores in 15 states.
A spokeswoman for Wal-Mart said Monday the raw sprouts were sold by Caldwell Fresh Foods of Maywood, Calif.
The 15 states where Wal-Mart stores bought the tainted sprouts are Alabama, California, Georgia, Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Missouri, Mississippi, Nebraska, Nevada, Oregon and Wisconsin.
The federal Centers for Disease Control said last week that the sprouts appear to have sickened at least 22 people in 10 states, including a baby in Oregon. Eleven of those sickened were in California.
The sprouts were sold in at least seven other stores in California, including Trader Joe's.
