This bill introduces a new chapter, Chapter 69, to Title 39 of the Idaho Code, which establishes regulations regarding the use of human fetal tissue in products. It mandates that any product containing ingredients or additives derived from human fetal tissue must include explicit labeling to inform consumers of such inclusion. This requirement applies to vaccinations and medical products, and manufacturers are held strictly liable for violations, while retailers are liable only if they had actual knowledge of the labeling requirement and failed to comply. The bill also empowers the attorney general to seek injunctive relief and impose civil penalties for violations.

Additionally, the bill outlines an affirmative defense for manufacturers and retailers, which includes conspicuous consumer information during the purchase process and the establishment of written compliance policies. It defines "human fetal tissue" as tissue or cells obtained from a deceased human embryo or fetus, encompassing various biological materials derived from such tissue. The act is set to take effect on July 1, 2026, due to an emergency declaration.
