 The normal dose of allyl cyanide contained in a meal is shown to be much lower than the doses used in animal studies.The daily level at which behavioural effects were demonstrated is 500 μg/kg bodyweight, whereas the daily human consumption amounts to 0.12 μg/kg.Although the dose-response relationship is still to be examined, it is therefore thought that allyl cyanide has no potency as a neurotoxicant when consumed in vegetables.
