The report says that the import is already banned in India, Egypt and Saudi Arabia. We have to look at our responsibility for making limited financial resource go as far as possible and feed as many people as possible, but obviously we need to be aware of the dangers there may be. This variety of lentil is non toxic when eaten at small dose. I am not surpised that it got a 'fit for human consumption' from the Australian Govt. It used to be eaten in some parts of France with no adverse effects.
Problems arise when it becomes a staple food.
In Bangladesh, during famine periods, people tend to consume higher quantities of this lentil which is more resistant and this results in epidemics of lathyrism. Memories of what occured in the 1974 famine is still present. You should get all the info you need about this topic from the local institute of nutrition. I would in any case avoid distributing this food as a famine relief food in Bangladesh since you are not sure to prevent over consumption in some cases. Neurological damage can be severe and is irreversible.
