When Bayer's Cutter Laboratories discovered their Factor VIII blood products were contaminated with HIV, they continued selling old unheated stock to markets in Asia and Latin America for over a year after introducing a heat-treated version in the US. Internal memos from 1983 acknowledged 'strong evidence' AIDS was transmitted through plasma products. An estimated 10,000+ hemophilia patients worldwide were infected with HIV. Bayer paid $600 million+ in settlements.
