Virginia Public Procurement Act; purchase programs for local farm or food products. Directs all state agencies to implement a purchase program for local farm or food products, defined in the bill, in order to reach a goal by 2035 of 20 percent of all the food and food products purchased by state agencies being local farm or food products. The bill also provides that for any public body partially or wholly funded by the Commonwealth, in which the total contract cost for food or food products is in excess of $25,000 per year, such public body shall implement a purchase program for local farm or food products in order to reach a goal by 2035 of 10 percent of all the food and food products purchased by such public bodies being local farm or food products. In order to meet such goals, state agencies and public bodies are authorized to give a preference to an otherwise qualified bidder who will fulfill the contract through the use of local farm or food products over the lowest responsible bidder so long as the cost included in the bid for the local farm or food products is not more than 10 percent greater than the cost included in the other bids.
