Food manufacturers selling products such as "cauliflower rice" could face new labeling restrictions in Louisiana, under a bill in the Legislature.The Senate voted 34-0 Monday for a "truth in labeling" measure that adds protections for meat, rice and sugar producers.Sen. Francis Thompson, a Delhi Democrat, says he wants to ensure consumers know what they're buying.His proposal is similar to legislation signed in Arkansas. It would ban companies from classifying lab-grown meat products or meat substitutes as meat, or they'd face fines. They would be unable to call something sugar if it doesn't come from a plant-based simple sugar or sucrose.The Plant Based Foods Association says the restrictions are unnecessary and products already are clearly labeled.The House next debates Thompson's bill.
