The main purpose of this legislation, known as the DONOR Milk Act, is to improve the safety and regulation of pasteurized donor human milk. This act aims to ensure that the milk provided to infants who are not the biological children of the donors is safe for consumption and meets specific health standards. Key provisions of the act include defining what constitutes pasteurized donor human milk, which is milk expressed by a mother and donated for use by another infant, and has been processed without any additives.
