In EU unprocessed apricot kernels are forbidden (only if used for consumption) since 2017:
https://eur-lex.europa.eu/legal-content/EN/TXT/PDF/?uri=CELEX:32017R1237&from=EN.
I think this statement is actually wrong:
'Amygdalin is the major cyanogenic glycoside present in unprocessed apricot kernels and is degraded to hydrocyanic acid (cyanide) by chewing'.
In the Netherlands it is not for sale anymore since a year ago a man almost died after eating apricot kernels as a snack.
It's still for sale in Germany (for example Amazon), but it has a warning sticker: not for consumption.
According to
The Little Cyanide Cookbook; Delicious Recipes Rich in Vitamin B17 there are also many other foods which contain B17.
https://www.amazon.com/Cyanide-Cookbook-Delicious-Recipes-Vitamin/dp/0912986379For example lentils which contain above 100 mg B17 per 100 g food. The concentration of B17 is much lower than seed kernels (above 500 mg per 100 g), but it is usually eaten in higher quantities.
