As with all NJ counties, retail food licensing is a MUNICIPAL function. The Middlesex County Office of Health Services conducts the inspections (goal: at least twice/year) but the operating license is issued and priced by each municipality's ordinance. Typical NJ municipal fees run ~$100-$500/yr. Example within the county: North Brunswick and Metuchen publish their own food-establishment license fee schedules. Left null - no single county fee.
Turnaround: Not published. Plan review may be required before a municipality issues a new retail-food license.
Mobile/food-truck licensing is municipal. Operators need a satisfactory inspection from the county Office of Health Services plus a retail food license from the base municipality and approvals in each town they operate in; a commissary is required. County did not publish a set fee - left null.
