Research Facilities and Testing Facilities That Use Animals - Prohibitions and Adoption Requirements (Animal Research Modernization and Best Practices Act of 2026)

HB 666, the Animal Research Modernization and Best Practices Act of 2026, prohibits research and testing facilities in Maryland from using certain dogs and cats for research or testing and bans specific procedures on them. The bill requires facilities to use alternative test methods - such as computer modeling or cell-based tests - when they are scientifically equivalent and approved by federal agencies, reducing reliance on traditional animal testing. It also extends adoption requirements for dogs and cats used in research to testing facilities, ensuring animals are made available for adoption when no longer needed. The bill sets clear standards: animal testing must be limited to cases where no alternative exists, with the minimum number of animals used and humane treatment prioritized.
