Amid investigations of salmonella found in peanut butter, an official of the U.S. Food and Drug administration confirmed Wednesday that the contaminated peanut butter originated in a plant in Georgia.

The Salmonella Typhimurium bacteria was found in an unopened container of King Nut peanut butter which was made in a plant of the company Peanut Corp. of America in Blakely, Georgia, director of the FDA's Center for Food Safety and Applied Nutrition said, according to Bloomberg.

The report dismisses possibilities that the bacteria was caught after the peanut butter products were shipped.

Peanut Corp. of America has recalled peanut butter and peanut paste which were distributed to institutions, food service industries, and private label food companies. Also Kellogg's and General Mills have recalled some of its products.

Major national brands of jarred peanut butter are not affected by the PCA recall. Peanut Corp. of America didn't sell directly to customers from retail stores, the FDA says in a statement on its website.
