Before any person, except permittees under Section 3.23 of this Act, shall engage in buying, selling or processing wild game for the purpose of buying, selling or shipping the same, including the carcasses of fur-bearing mammals, for public consumption, he shall first procure a license to do so from the Department. Dealers in deer, or any parts thereof, legally taken and possessed in and transported from, other states, shall also be licensed under the provisions of this Section. All such deer, or parts thereof, shall be marked with permanent irremovable tags, or similar devices, to establish and retain their origin and identity.
The terms "buying or selling" include buying or selling by hotel keepers, restaurant keepers and others engaged in buying or selling prepared foods for consumption.
A permit shall be procured for each separate market or place of business operated by any person who sells wild game for public consumption and for each vehicle from which game or fur-bearing mammals are sold. Such permits shall be conspicuously displayed at all times.
This permit shall be known as a processed wild game dealer's permit. It shall be issued by the Department for a fee of $25.00 annually and shall expire on March 31st of each year. The Department may prescribe the necessary forms as may be desirable for the maintenance of records by the licensee, to record all transactions in wild game that may be marketed under the provisions of the laws of this State and game imported legally from other states.
Nothing in this Section shall be construed to give the holder of a processed wild game dealer's permit authority to take game birds, game or fur-bearing mammals in their wild state contrary to other provisions of this Act. The person in possession of such game birds and mammals has the burden of proving the legality of his possession.
