Any infant milk substitute or feeding bottle or infant food or container thereof, in respect of which any provision of this Act has been or is being contravened, shall be liable to confiscation:
     Provided that where it is established to the satisfaction of the court adjudging the confiscation that the person in whose possession, power or control any such substitute or bottle or food or container is found is not responsible for the contravention of the provisions of this Act, the court may, instead of making an order for the confiscation of such substitute or bottle or food or container, make such other order authorised by this Act against the person guilty of the breach of the provisions of this Act as it may think fit.
