The dal was banned in 1961 as its consumption was linked to neurological disorder lathyrism, the paralysis of legs.
"Based on scientific evidence and details that are available from experts, we reached the conclusion that lathyrism occurs only when it is taken in very large quantity. There is no evidence of lathyrism occurring due to consumption of the dal in last 20 years," Food Safety and Standard Authority of India (FSSAI) CEO Pawan Kumar said.
"The consultation will be held for 60 days during which people can give their inputs and suggestions on the matter," he said.
The decision to lift ban on Khesari Dal came after the Indian Council of Medical Research (ICMR) recommended FSSAI that three variants of the dal are safe for use.

They said Khesari Dal is a rich source of protein and contains little amount of toxins like any other food item.
"It depends on what quantity one is eating. Earlier, people used to have it three times a day because of its affordability. In that case the toxicity level may go up. But now nobody takes it day-in and day-out," the Ministry official said.
