Prevention

The following are precautionary measures that can be taken to avoid the spread of bagassosis: # Dust control-prevention /suppression of dust such as wet process, enclosed apparatus, exhaust ventilation etc. should be used # Personal protection- masks/ respirators # Medical control- initial medical examination & periodical checkups of workers # Bagasse control- keep moisture content above 20% and spray bagasse with 2% propionic acidPark's textbook of preventive & social medicine 21st edition page-747

History

Bagassosis was first reported in India by Ganguly and Pal in 1955, in a cardboard manufacturing plant near Kolkata. India has a large cane sugar industry. The sugarcane fibre which, until recently, went to waste, is now utilised in the manufacture of cardboard, paper and rayon.
