Illinois Statutes Chapter 410. Public Health § 637/10. Deception prohibited

(a) It is a Class B misdemeanor for any person to make any oral or written statement that directly or indirectly tends to deceive or otherwise lead a reasonable individual to believe that a non-halal food or food product is halal.

(b) The presence of any non-halal food or food product in any place of business that advertises or represents itself in any manner as selling, offering for sale, preparing, or serving halal food or food products only, is presumptive evidence that the person in possession offers the food or food product for sale in violation of subsection (a).

(c) It shall be a complete defense to a prosecution under subsection (a) that the defendant relied in good faith upon the representations of an animals' farm, slaughterhouse, manufacturer, processor, packer, or distributor, or any person or organization which certifies or represents any food or food product at issue to be halal or as having been prepared under or sanctioned by Islamic religious requirements.
