However, such power shall be subject to and not inconsistent with the rules and regulations of the state board of health touching the health interests of the county in which such municipality is situated. In the absence of an explicit agreement to the contrary between the state board of health and such municipality, enforcement of municipal laws shall be the responsibility of the municipality.
