Abstract

Filling paddy bags by hand is a common task during harvesting, but it can cause musculoskeletal disorders (MSDs) in various body regions. The current study aims to evaluate posture and find an association between MSDs and body posture scores. The Nordic questionnaire and rapid entire body assessment (REBA) were used to collect MSDs and postures from farmers. The MSD in various body regions (neck, elbows, hands, upper back, knees, ankles, lower back, hips, thighs, and buttocks) was found to be 6.7%, 10%, 3.3%, 6.7%, 16.7%, 20%, and 10%, respectively, during the last 12-month period. In REBA score findings, holding bags, filling the bucket, and the bag were found to have a very high risk of causing MSDs. Despite the fact that MSDs are not very common among farmers who engage in paddy bagging tasks, posture analysis reveals what causes MSDs. Further investigation is needed to improve and reduce MSDs.

Abstract

The current study was conducted to assess the freshness and pattern of spoiling of Nile tilapia (Oreochromis niloticus) stored at various temperatures. Nile tilapia purchased from NAQDA - Dambulla with same harvest and size; transported to the laboratory in ice boxes. Fish were randomly divided into four equal groups and stored in 4°C (n=6), -4°C (n=6), -10°C (n=6) & -20°C (n=6) temperatures. Basically, samples were evaluated for 41 days; daily for first five days & then once in two days for six days, once in three days for nine days & finally once in a week for 3 weeks. Organoleptic and demerit points were calculated. From the results, there were significant differences (p<0.05) in freshness of tilapia stored in four different temperatures. However, freshness deterioration in -10°C and -20°C were relatively slow but in 4°C it was rapid. In Sensory evaluation rejection was held at after 3 days (4°C), 14 days (-4°C), 27 days (-10°C) and 34 days (-20°C). Significantly positive correlation was observed between freshness deterioration and storage period r=0.99 (4°C), r=0.98 (-4°C), r=0.90 (-10°C) and r=0.92 (-20°C).
