Now, while the average consumer likely hasn't heard of Castle Cheese Inc., the company supplies cheese (and filler, apparently) to the titans of the grocery world who then sell it under their own labels. Perhaps you've heard of Jewel-Osco, Wal-Mart, Whole Foods, and Kraft. Here's a particularly damning passage on the swill cheese found in your local grocer's dairy section:
"Essential Everyday 100% Grated Parmesan Cheese, from Jewel-Osco, was 8.8 percent cellulose, while Wal-Mart Stores Inc.’s Great Value 100% Grated Parmesan Cheese registered 7.8 percent, according to test results. Whole Foods 365 brand didn’t list cellulose as an ingredient on the label, but still tested at 0.3 percent. Kraft had 3.8 percent."
Generally speaking, the FDA spends its time making sure the food you eat is safe -- rather than going after companies who defraud their customers. But as evidenced by a $16 billion, worldwide scam where mobsters adulterate olive oil with slag ingredients, there's plenty of money to be made from peddling inferior products to John Q. Cheeseeater.
