Requires the Department of Health and Human Services to set contamination limits for morphine, codeine, and other specified compounds in poppy seeds and to treat any poppy seeds that exceed those limits as adulterated and banned from interstate commerce. It also preserves existing law that contaminated poppy seeds can still be regulated under the Controlled Substances Act. The bill sets deadlines for rulemaking: a proposed rule within 1 year and a final rule within 2 years of enactment.
