21 U.S.C. § 148 — Powers of State with respect to milk or cream lawfully imported

This section is a single, undivided rule protecting State and local power over milk and cream. Nothing in this subchapter is meant to reduce that power, and nothing in it should be read as reducing that power. A State, or any political subdivision of a State, such as a city or county, keeps full authority to regulate the shipment of milk or cream into its own borders. It also keeps authority over how that milk or cream is handled, sold, or otherwise disposed of within its borders. This state and local authority applies once the milk or cream has been lawfully imported under this subchapter's rules. In short, this subchapter's federal import rules for milk and cream do not override state and local regulation of that milk or cream once it arrives.
