No person may knowingly sell or offer for sale any food product marked, stamped, tagged, branded, labeled, or represented as halal when that person knows that the food product is not halal and when the representation is likely to cause a prospective purchaser to believe that it is halal. Such a representation may be made in any language, orally or in writing, or by display of a sign, mark, insignia, or simulation.
