The food company ConAgra is agreeing to pay more than $11 million for shipping salmonella-tainted peanut butter from a Georgia plant.

The Centers for Disease Control and Prevention linked the tainted Peter Pan peanut butter to the outbreak, which affected more than 700 people in 2006 and 2007. It prompted a nationwide recall.

No deaths were confirmed, but authorities believe thousands more cases went unreported.

A federal plea agreement, announced Wednesday, says the contamination was likely the result of faulty food safety equipment, a leaky roof, or other problematic conditions at the ConAgra plant in Sylvester, Georgia.

In the agreement, the Omaha-based company acknowledges that some employees did not know how to properly analyze the results of tests meant to detect salmonella.
