The Alder Hey organs scandal involved the unauthorised removal, retention, and disposal of human tissue, including children’s organs, during the period 1988 to 1995. During this period organs were retained in more than 2,000 pots containing body parts from around 850 infants. These were later uncovered at Alder Hey Children's Hospital, Liverpool, during a public inquiry into the organ retention scandal. The scandal led to the Human Tissue Act 2004, which overhauled legislation regarding the handling of human tissues in the UK and created the Human Tissue Authority.
