It started as a small cluster of salmonella cases. Now it's a massive outbreak with nearly 700 people suffering nationwide. More than 200 companies have recalled products, and the list grows as the investigation continues.
What makes it so tough to track the problem? The trouble started with contamination at a Peanut Corporation of America (PCA) plant in southwest Georgia. PCA doesn't sell directly to us in the supermarkets—they sell peanut butter in bulk to institutions and food manufacturers for use as an ingredient in their products. Many products made with the tainted peanut butter have been widely distributed, and that's why the recalls go back more than two years.
