Far more in big cities such as NY than in modern, spacious buildings elsewhere.
Outside NYC government health departments are far more stringent when it comes to inspections, especially of institutions.
I served a term on our local Health District board. The director of public health even shut down the kitchens in our public high school when they did not meet standards. They were put back in order in less than 72 hours and now have monthly inspections. not semi-annually.
The assisted living center my mother OBM lived in her final years, no longer has an independent cook under a mashgiach. Instead it is professionally run by Sodexo (the institutional arm of Marriott) with true professionals under full time rabbinical supervision. Much cleaner, healthier meals and lower costs based on economy of scale.
Our area Jewish Federation is considering a central commissary to provide centrally prepared meals for serving by day schools, yeshivos, meals on wheels, senior centers, day camps, etc. All these constituent agencies who accept Federation money could be well served by professional food service and reduced cost/higher quality meals.
