Per the Houston Chronicle, a week after ConAgra Foods Inc. recalled peanut butter from its Georgia plant after a salmonella outbreak, the Center for Disease Control confirmed the presence of the dangerous germ.

No deaths have been confirmed, although a Pennsylvania family filed a lawsuit Wednesday claiming a relative died from eating tainted peanut butter.

Opened jars from people who were sickened in New York, Oklahoma and Iowa tested positive for salmonella, said Dave Daigle, a spokesman for the CDC in Atlanta.

"Now the question becomes, how did the salmonella get in the jar," Daigle said.

ConAgra Foods Inc. last week recalled all Peter Pan and Great Value peanut butter made at its Sylvester, Ga., plant after federal health officials linked the product to a salmonella outbreak that has sickened at least 329 people from 41 states since August.
