Hypoglycin A (HGA) is a toxic amino acid that is naturally produced in unripe ackee fruit. In 1973, the U.S. Food and Drug Administration (FDA) placed a worldwide import alert on ackee fruit, which banned the product from entering the United States.
The ackee has great socioeconomic importance to Jamaica, providing vital employment opportunities, so the import alert (ban) on its importation into the United States in the 1970s due to safety concerns was a significant blow. This chapter discusses
