Being in the food distribution end of the business; federal regulation (HACCP) has definitely improved food safety, by codifying the entire process from the raw materials to the food on your plate...
Now this new proposal simply is a political ploy... and completely not needed...
Do I follow the 160F rules on thick pork chops? No... Don't eat here if you don't like it.
Even HACCP has no Constitutional basis under article 1, section 8. The States can handle it.
