There needs to be some perspective here:
The greatest improvement for public health in history was the deployment of sanitation/sewage systems.Second greatest improvement is sanitized water systems. Everything else is window dressing in relation to those.
The public risk is much greater in the case of a sanitation failure at a restaurant that serves 100s of people a week, vs. a home restaurant that might serve 4 people a week. An inspection regime that doesn't acknowledge or allow for these differences in exposure is not good engineering or good public policy.
This is the same thing with butcher operations that produces ground beef from many dozens of steers at a time vs. an operation that processes one steer at a time. Or a diary that produces and pasteurizes milk from hundreds of cows vs. one that distributes raw milk from a few cows at a time. The attendant public health risks diverge wildly.
Since the public risk is vastly different in scale, the government interest should be vastly different in scale. Of course, we know this isn't the case. The main purpose of a government bureaucrat will always evolve toward increasing the power and scope of the bureaucracy. Always.
Exhibit A.Exhibit BWith regards to food inspections and preparation standards... there's no reason that a free market of "food preparation" certification companies couldn't perform this function better than any government.
There could be competing standards and processes and inspection regimens. People selling food to the public could pay these companies to the level of certification that they deem appropriate to their business. The displayed certificate could inform the public of that information. And then the public could decide what food to purchase or where to eat based on that and any other of their preferences. The types of personal preferences that government bureaucrats can never consider.
So, that way, 'I' could decide to take my chances by eating at John and Sue's pop-up home restaurant, where they only have a sanitation training certificate but no regular inspections.
