CNN - Salmonella outbreak linked to 2 peanut butter brands

A salmonella outbreak that has slowly grown to nearly 300 cases in 39 states since August has been linked to tainted peanut butter, federal health officials said Wednesday.

About 85 percent of the infected people said they ate peanut butter, CDC officials said.

How salmonella got into peanut butter is still under investigation, Lynch said.

The Food and Drug Administration warned consumers not to eat certain jars of Peter Pan or Great Value peanut butter because of the risk of contamination.

The affected jars have a product code on the lid that begins with the number "2111." The affected jars are made by ConAgra in a single facility in Sylvester, Georgia, the FDA said.

First of all, it seems odd that salmonella would be in peanut putter. Second, it seems odd that only 85 percent of the people effected said they ate peanut butter. Third, I have a half-eaten jar of Peter Pan peanut butter with a product code beginning "2111". Since no one got sick eating the first half does that mean it is safe to finish or should I just throw it out?

UPDATE: This article at Market Watch says:

The company added that consumers should discard the affected peanut butter, but save the product lid to get a full refund.

The problem is it doesn't tell you what to do with the lid to get the refund. (Updated info here)
