Key points
This outbreak is over. CDC and public health officials in several states investigated a multistate outbreak of E. coli and Salmonella infections linked to alfalfa sprouts. Raw and undercooked sprouts are a common cause of foodborne illness. Cooking sprouts until steaming hot can lower your risk. Always take steps to prevent getting sick from E. coli and Salmonella.

The true number of sick people in this outbreak was also likely much higher than the number reported. This is because many people recover without medical care and are not tested for E. coli or Salmonella.
