Assessing Self-reported Occupational Hazards of Manure Applicators in the Upper Midwest.

Manure management on farms presents potential risks to human health and safety, including infectious, chemical, and physical exposures that may result in injury or fatality. Toxic gases and confined spaces are among the most common hazards. These hazards are especially salient for the Upper Midwest of the United States. This study characterizes the occupational health and safety practices and experiences of manure applicators in Minnesota. This cross-sectional study surveyed 162 commercial manure applicators about their work characteristics, safety practices, and health and safety experiences. Respondents reported an average of 17 hours per day applying manure during the busy season, which typically occurs several weeks each year. One hundred and thirty-one (90%) of 145 respondents did not regularly use gas monitors during application. Thirty-three (37%) of 90 respondents reported at least one symptom of gas exposure during manure application work. Those that worked with swine manure were more likely to report symptoms of gas exposure than those who did not work with swine (OR 9.5; CI: 2.0, 89.0). Those that had entered confined spaces were more likely to report symptoms of gas exposure than those who had not entered confined spaces (OR 4.4; CI: 0.1, 1.1). Fourteen (9%) of 150 respondents reported being injured when applying manure. Manure work can be hazardous and may be associated with injury and gas exposure. These findings offer a starting point for future research and intervention to protect and improve the health and safety of applicators.

It Takes a Village: A Novel Process for Responding to Emerging Issues in Agricultural Health and Safety.

Agricultural and food production systems are constantly evolving in response to societal and environmental factors. These sectors are also laden with occupational hazards, creating an opportunity for emerging and re-emerging issues such as emerging markets and changing worker demographics. The Upper Midwest is a region of intensive agricultural production, with many states leading the United States in livestock and crop production. As a National Institute of Occupational Safety and Health Center for Agricultural Safety and Health, the Upper Midwest Agricultural Safety and Health Center (UMASH) is tasked with protecting the health and safety of the region's agricultural workers. UMASH implements an Emerging Issues program to effectively respond to emerging and re-emerging issues impacting agricultural health and safety in the Upper Midwest. To direct such work, UMASH developed a novel Selection, Planning and Action Process Model. This model guides all stages of the UMASH Emerging Issues response and emphasizes the ongoing need for monitoring, evaluation, and feedback from agricultural communities. In conjunction with the UMASH Process Model, the International Association for Public Participation (IAP2) Spectrum of Public Participation frames the work of the Emerging Issues Program in meaningfully engaging the community of stakeholders across all stages.

The NIOSH Agricultural Centers' YouTube Channel: Time Series Modeling of Viewership of Agricultural Health and Safety Videos.

We sought to understand the mechanism underlying the growth trajectory in the United States Agricultural Safety and Health Centers YouTube channel. We also explored the benefits and limitations of using YouTube analytics to evaluate the impacts of public health interventions involving YouTube. Time series analysis of total views, total watch hours, average duration of watch time, and number of subscribers were assessed to determine the monthly patterns of non-seasonal and seasonal components in the data from 2013 to 2020. Health, safety, and animal handling video views were summarized descriptively across time and season. Lastly, time series regressions were used to determine the type of video that best predicted growth in the channel viewership metrics. The time series were not random but could be explained by autoregressive and moving average correlation structures. Health videos were the strongest predictors of future growth but were not the most watched type of video. Strong seasonality components indicated that videos were most watched during periods of high agricultural activity, but less so during the winter months. Generally, growth in YouTube viewership metrics was explained by past month viewership predicting future viewership. Outreach and media content may produce spikes of increased interest, but in order to sustainably grow the channel over time, Ag Centers and other agricultural stakeholders should continue to focus on the value of particular content to potential viewers, how and when content is released, and strategic promotion of the channel and its videos.
