How Much Cyanide Is Lethal?
According to the Centers for Disease Control and Prevention, 1-2 mg/kg is a fatal oral dose of cyanide for a 154 lbs. (70 kg) man. You would need to finely chew and eat about 200 apple seeds, or about 20 apple cores, to receive a fatal dose.
The Agency for Toxic Substances & Disease Registry says that exposure to even small amounts of cyanide can be dangerous. Exposure to cyanide can harm the heart and brain, and even lead to coma and death. They add that people should avoid eating the seeds of apples, and pits of peaches, apricots, and cherries.
