....but the FDA guidelines has improved food safety....
That was your point, was it not?
I would agree the states can handle their food safety issues, but having an over reaching nationwide guide line resolves potential different state standards....
Currently California is causing an egg issue because they exceed federal guild lines...and other states are having to comply to California regs...driving up the price of eggs...
The feds need to stick with the rules. The States will manage, including telling CA to pound sand if required.
