In any product liability action, a defendant shall not be liable if the defendant proves that any of the following applies:
1. The defect in the product is alleged to result from inadequate design or fabrication, and if the plans or designs for the product or the methods and techniques of manufacturing, inspecting, testing and labeling the product conformed with the state of the art at the time the product was first sold by the defendant.
2. The proximate cause of the incident giving rise to the action was an alteration or modification of the product that was not reasonably foreseeable, made by a person other than the defendant and subsequent to the time the product was first sold by the defendant.
3. The proximate cause of the incident giving rise to the action was a use or consumption of the product that was for a purpose, in a manner or in an activity other than that which was reasonably foreseeable or was contrary to any express and adequate instructions or warnings appearing on or attached to the product or on its original container or wrapping, if the intended consumer knew or with the exercise of reasonable and diligent care should have known of such instructions or warnings.
4. The proximate cause of the incident or incidents giving rise to the action was the repeated consumption of a food product that is not defective and unreasonably dangerous if consumed in reasonable quantities.
