To the casual observer, merging food regulations under one roof seems to make sense. Single food-agency proponents like to use the example of pizza. Cheese pizza falls under the exclusive jurisdiction of FDA, but if pepperoni or sausage is added, then USDA steps in.
Eggs are another example.
FDA regulates the safety of shell eggs, while processed egg products largely fall under USDA's domain. And states can add to the confusion as well. These examples call for greater simplicity and uniformity of regulatory responsibilities. Certainly, they fuel the impulse to hold someone ultimately accountable for the nation's food safety system. America's food safety system got its start in 1906 with the enactment of the Pure Food Act.
