In all counties or municipalities which have provided, or which have aided in providing, a budget out of which the claims, demands and expenses of the health department shall be paid, then such claims and demands of the health department shall not be a claim against the county or municipal treasury, but shall be paid out of the budget or funds, provided the county or municipality has paid into the budget its aliquot, or required part, of such budget.
