The Food and Drug Administration had initially said Peanut Corporation of America (PCA) retested products after getting an initial positive result for Salmonella. The FDA and PCA said the company shipped the goods after follow-up tests came back negative. Today, the FDA amended the "483" and said the company sent out peanut butter, chopped peanuts and peanut meal that had tested positive even before it got back any negative findings.  Also, in some instances PCA shipped product before it received tests back and then did not recall.
