House File 377 introduced by Representative Jeff Shipley intended to ban foods containing GM products, lab-grown protein and insect protein in school feeding.  The bill also incorporated provisions for labeling plant-based protein. The bill was rejected by a subcommittee of the Iowa House of Representatives based on the basis of impracticality.

Legislators at state level frequently propose and sponsor bills that favor agricultural products despite obvious conflicts with constitutional requirements.  These "feel good" bills are intended to generate support among constituents and are intended to burnish the "pro-farm” credentials of incumbents.
