Federal officials have announced a recall of all products containing peanut paste or peanut oil produced over the past two years at a Georgia plant at the center of the current salmonella outbreak.
In a briefing Wednesday, the federal food safety officials said the plant owner -- Peanut Corp. of America -- had agreed to the recall.
More than 500 people have gotten sick in the salmonella outbreak, which is linked to at least eight deaths.
Wednesday's recall follow reports by federal inspectors that salmonella had been found previously at least 12 times in products made at the plant. Inspectors found that the tainted peanut products were retested, then shipped to customers.
NBC News is reporting the operators of a Georgia plant at the center of the salmonella investigation may have knowingly sold contaminated products.
As more food companies recalled products that contain peanut butter paste, the Food and Drug Administration revealed that at least 12 times over the past two years, the Georgia-based Peanut Corporation of America has released products for consumption after they tested postive for salmonella but then tested negative in a second test.
The FDA also alleges PCA took no steps to improve the cleaning or manufacturing methods after salmonella was found in its plant, a clear violation of the law.
All this information came out as the government reports a slight drop in the number of new salmonella cases.
So far, 501 people in 43 states and one person in Canada have been sickened. Of those, 108 have been hospitalized. Eight have died.
The Peanut Corporation of American says it has cooperated fully with the FDA from day one during the course of the investigation.
Meanwhile, the FDA says more than 180 products so far have been recalled.
