The CDC says ground beef is behind an E. coli outbreak that has sickened more than 109 people and hospitalized 17

Federal health officials said Friday that ground beef is behind an E. coli outbreak that has sickened at least 109 people, 17 of whom have been hospitalized.

No common brand or supplier of the tainted meat has been identified yet, and the investigation is ongoing, the Centers for Disease Control said in a post on its website.

People sickened by the outbreak reported eating ground beef both at home and in restaurants.

The CDC said people can continue to consume ground beef, but should make sure to cook it thoroughly.
