An E. coli outbreak reported in seven states has been traced back to a chicken product sold at Costco Wholesale stores.

FOX News' Eben Brown reports:

19 people in seven states, of which five have been hospitalized, contracted E. coli from rotisserie chicken salad sold at Costco.

Those states are California, Colorado, Missouri, Montana, Utah, Washington State, and Virginia. But the Centers for Disease Control now says any of this product sold at any Costco in the U.S. on or before November 20, could be tainted and should be thrown out.

That even goes if you've already eaten some and have not yet gotten sick. The Costco item number on the package is 37719.
