Background & Objectives: Dairy workers have exposure to wide range of musculoskeletal disorders in different organs. A little research has been done on dairy worker and their training on safe working in our country. On the other hand in the industries with more workers it is often easier to implement safety programs.

Methods: This interventional study was conducted on 50 cattlemen in Abarkooh city. Working posture was assessed by WISHA and Man-TRA methods and face to face training was then given on carrying and lifting. Finally the posture was investigated two months after intervention by Man-TRA and WISHA methods.

Results: The results of the evaluation by WISHA before the intervention show that 84.3% of dairy workers have desired status. After the intervention, despite the improvements in some items such as hands and upright back position at work and repeating the task; 83/6% had the desired status because of non-compliance with the load weight. Statistical analysis of the data also gave same results. The results of Man-TRA showed, training doesn't affect work period of time, but increase and decrease in stress score after the intervention on leg, neck, and shoulder is considerable. Overall, despite the desirable final scores, increase in scores of the lower limbs and decrease in neck/shoulder scores are important.

Conclusion: Despite the optimum and favorable conditions in Abarkooh dairies, the training programs to improve physical conditions of the back and neck as the most troubled part of the study, was reported to be effective.
