"During the past two decades, the food industry has taken over much of the FDA’s role in ensuring that what Americans eat is safe. The agency can’t come close to vetting its jurisdiction of $1.2 trillion in annual food sales.
In 2011, the FDA inspected 6 percent of domestic food producers and just 0.4 percent of importers. The FDA has had no rules for how often food producers must be inspected.
The food industry hires for-profit inspection companies -- known as third-party auditors -- who aren’t required by law to meet any federal standards and have no government supervision. Some of these monitors choose to follow guidelines from trade groups that include ConAgra Foods Inc. (CAG), Kraft Foods Inc. and Wal-Mart."
