Where food or appliance in connection with which there is a breach of any provision of this Act, or any of the regulations made thereunder, is sold in an unopened package, any person who appears from any statement thereon or attached thereto to have imported or manufactured or prepared that food or appliance or to have enclosed it in such package shall, unless he proves the contrary, be deemed to have so imported, manufactured, prepared or enclosed that food or appliance and shall be liable to the same fine as if he had actually sold that food or appliance, as the case may be.
