Hemp and Food Safety
All food and food ingredients sold in Tennessee, or used as ingredients in food products produced in Tennessee, shall originate from an approved source. An approved source means that it is inspected by regulatory authority. For food products produced in Tennessee that means that they are inspected and permitted by the Tennessee Department of Agriculture. Approved manufacturers will be regulated under 21 CFR 117 parts A and B. Products that are made outside of Tennessee and used in food products produced in Tennessee must show evidence of inspection or oversight by a regulatory authority.
