Manure Management

The Upper Midwest experienced a number of severe injuries and fatalities in the last few years related to the management of manure from animal agriculture operations.

The potential hazards from manure have been known for decades, but as the industry changes and more comprehensive and complex manure management takes place. UMASH is involved with two emerging issues associated with manure: 1. Occupational risks and exposure for custom waste applicators and 2. Using manure solids as bedding on dairy farms investigating both animal and human health implications.

UMASH collaborated with Extension to develop and distribute a survey to the Minnesota Custom Waste Applicators. The survey focused on occupational and possible zoonotic risks due to the nature of the work. A manuscript of the survey is underway with the intention of publishing in 2020 or 2021. Educational resources are being considered with respect to the current safety and health concerns which can be used within the state wide workshops to build awareness and reinforce prevention.
