DeKALB | A peanut butter recall forced NIU dining halls to discard Peter Pan and Great Value brands of peanut butter with a product code beginning with “2111” on the lid.

Forty-one states have been affected by an outbreak that started when salmonella was found in some batches of peanut butter. The Food and Drug Administration advised consumers to throw away any jar of the affected peanut butter purchased since May 2006.

Seven of the 329 people reportedly affected by the outbreak were from Illinois, according to a statement released by the Centers for Disease Control and Prevention.

Ralph Chaplin, director of Residential Dining, said they found out about the recall the day it was announced and removed all brands the same day.

“Skippy is being used in the halls for large-size containers,” Chaplin said. “We did have some Peter Pan portion control-size product.”

This was the first time that a recall has been made for peanut butter, Chaplin said.

The salmonella outbreak was linked to tainted peanut butter produced by ConAgra Foods Inc. at a plant in Sylvester, Ga.

The Great Value brand, which is also made by companies besides ConAgra, is a Wal-Mart brand.
