Urea in puffed rice

Puffed rice is a very popular food item in urban and rural areas of Bangladesh. It is consumed by people of all ages. Some traders mix urea to make rice white and puffy. Still some good quality puffed rice is produced in villages of our country. But these are lost in the crowd of the colourful bags of urea-mixed puffed rice produced by big traders. The authorities concerned should take action against these culprits in the interest of public health.
