Understanding hazards faced by manure applicators

Understanding hazards faced by manure applicators

JUNE 2022

Manure from animal agriculture offers beneficial nutrients for crops and plants; however, the Upper Midwest has seen several severe injuries and fatalities in the last few years related to manure management. As manure management practices change and become more complex (and potentially more dangerous!), UMASH wanted to better understand this emerging issue in agricultural health and safety. Therefore, UMASH collaborated with University of Minnesota Extension colleagues to develop and distribute a survey to Minnesota Custom Waste Applicators about the nature of their work and experiences with injury and illness.

Devon Charlier and co-authors Melissa Wilson, Chryseis Modderman, Erin Cortus, Kevin Janni, Carol Peterson, Megan Schossow, Bruce Alexander, and Jeff Bender summarized the results of this study in “Assessing Self-reported Occupational Hazards of Manure Applicators in the Upper Midwest,” a recent peer-reviewed publication in the Journal of Agromedicine.

This study suggests that manure work is hazardous. Among surveyed manure applicators,

  • 20% reported gas exposure symptoms related to their manure application work. Those who entered confined spaces or worked with swine manure had increased odds of reporting such symptoms.
  • 9% reported injuries, some of which required a healthcare provider visit or a trip to the emergency room.
  • Many indicated long work hours and fatigue as top concerns. On average, respondents worked over 18 hours per day during a “busy season,” which could last between two and four weeks. This is concerning, as fatigue can intensify other occupational hazards.

While the research about this emerging issue is ongoing, UMASH and collaborators will translate these findings into outreach materials to support the health and safety of those working with manure.
