Abstract

India is the second-leading country in production of cashew nut. Cashew nut are roasted or steamed before shelling. The study was conducted in cashew nut processing industries situated in Selsella and Mankachar blocks of Meghalaya and Assam. The purpose of this study was to compare the cutting strength of cashew nut shells influenced by roasting and steaming. The impact of manual shelling of cashew nut on occupational health of workers was also assessed by using ergonomic tools. The moisture content, colour, and hardness of cashew nut shell were measured. The processing of cashew nut influenced the cutting strength of cashew nut significantly. Steamed cashew nut shell was stronger than the roasted cashew nut shell. Hence, manually shelling of steamed cashew nut shell required more force compared to with that of roasted cashew nut shell. Four cashew nut processing industries, two each from Selsella and Mankachar block of Meghalaya and Assam, respectively were selected purposively. A group of 10 female workers from each industry were selected randomly as sample for this study. Ergonomic parameters: working Heart Rate, energy expenditure, rated perceived exertion, hand grip measurements, RULA and REBA analysis were used to assess occupational health of workers. The results of the study showed that the workers of cashew nut industries were exposed to high occupational health and safety risk due to poor working environment, awkward working posture, repetitive and tedious job.

Keywords: Cutting strength of cashew nut, musculoskeletal disorder, occupational health, rapid upper limb assessment, rapid entire body assessment
