. In 2016, the European Food Safety Authority reported that eating three small bitter apricot kernels or half of a large bitter kernel would exceed safe consumption levels of amygdalin and potentially cause cyanide poisoning. The Food Safety Authority of Ireland advises against eating either bitter or sweet varieties of apricot kernel due to the risk of cyanide poisoning and advises consumption be limited to one to two kernels a day for an adult. They also advise against consuming bitter almond for the same reasons. In 1993, the

tested the cyanide content of two (8 oz) packages of bitter apricot kernels imported from Pakistan that were being sold in health-food stores as a snack. The results showed that each package, if consumed entirely, contained at least double the minimum lethal dosage of cyanide for an adult human; the product was removed from stores. There was one reported case in the medical literature of cyanide toxicity from apricot kernels from 1979 to 1998 in the United States, a non-fatal poisoning by purchased apricot kernels.
