Summary
Needleless injectors in swine production may improve efficiency and reduce injuries. This study evaluates their impact on worker health, productivity, and farm economics compared to traditional needles.
Area of Science:
- Occupational Health and Safety
- Agricultural Technology
- Biomechanical Engineering
Background:
- Modern swine production increasingly uses new technologies like needleless injectors.
- While potentially increasing productivity and reducing needlestick injuries, their impact on musculoskeletal disorder risk is unknown.
Purpose of the Study:
- To compare conventional needles with needleless injectors in swine production.
- To assess cost, productivity, injury rates, biomechanical exposures, and worker preferences.
Main Methods:
- Measuring muscle activity (EMG) and hand/wrist posture during injection tasks.
- Utilizing time-and-motion studies from video recordings to assess productivity.
- Analyzing injury claim data and conducting worker/manager interviews.
Main Results:
- Data collection on biomechanical exposures, injury rates, and worker feedback is ongoing.
- A cost-benefit model will integrate findings to assess overall impact.
Conclusions:
- Findings will inform the swine industry about the occupational health and economic effects of needleless injectors.
- Results are intended to be transferable to other animal production technologies.
