A combination of video conferencing and in-person training workshops were offered to school-based agriculture teachers in Montana, Utah, and South Dakota. Zoom webinar workshops were held with teachers during the COVID-19 pandemic. The five annual training topics included: Year 1) Tractor/Equipment Roll-over Hazards, Year 2) ATV/UTV Operation Hazards, Year 3) Tractor/Equipment Operation Hazards, Year 4) PTO/Entanglement Hazards, and Year 5) Agricultural Machinery Transport Hazards Associated with use on Public Roadways. To assess the influence of agricultural machinery safety training, students' journal reflections were collected through the Agricultural Experience Tracker. Students' production-based agricultural experiences were coded by USDA National Agricultural Statistics Service (NASS) Commodity Codes, describing students' safety reporting using Supervised Agricultural Experience (SAE) journal entries, and quantifying teachers' workshop participation. A total of 2,257 journal entries were reviewed from Montana, Utah, and South Dakota. A total of 760 unique student journal entries were associated with a teacher participating in the training program. Most student journal entries focused on machinery operations. A total of 49 journal entries specifically reported safety. A total of 203 journal entries recorded the use of tractors. A total of 160 agricultural production work entries (38.8%, n = 412) noted crop production as the agricultural production work experience.

This paper presents the major findings from the occupational safety research track of the workshop. This track identified existing hurdles to conducting occupational safety research including logistical barriers, intellectual property concerns, long timelines, and lack of funding. Considerations for developing a tracking or surveillance system for adverse events as well as exposure related to these technologies were also discussed, emphasizing the need for a comprehensive system. Finally, the priority occupational safety research needs identified during the session were related to human and non-human machine interaction, adoption of automation in the work setting, and event tracking/surveillance. To overcome barriers to research, collaboration between occupational safety researchers and technology developers is crucial. Enhancements to existing surveillance systems can facilitate better understanding of captured events. Additionally, prioritizing research on worker risk from robotics and autonomous machines in agriculture is essential.

Air samples collected indoors and at fan exhaust have highly similar bacterial diversity. At low indoor concentrations, specific microbial markers are still detectable in the air collected at the fan exhaust.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Abstract: &lt;/strong&gt;The incidence of animal and zoonotic diseases is expected to increase in the coming years, imposing the reinforcement of biosecurity measures for livestock operations. Airborne transmission of certain infectious agents underscores the importance of surveilling bioaerosols. However, having access to livestock operations for monitoring purposes is now challenging. Hence, it has become imperative to explore alternative strategies to assess indoor bioaerosols. This study aimed to compare bacterial diversity and quantify microbial markers found in bioaerosols indoors and at the fan exhausts of pig-finishing buildings (PFBs) and broiler chicken barns (BCBs). Bioaerosols were collected using a filter-based, high-flow rate air sampler in 12 facilities (10 PFBs and 2 BCBs) during the warm season in Eastern Canada, corresponding to maximal ventilation rate operations. Four farms-PFB-1, PFB-2, BCB-1, and BCB-2-were visited multiple times, while the other eight PFBs (PFB-3 to PFB-10) were visited once. At each farm, indoor air samples were paired with samples from the corresponding sidewall extraction fans. Amplicon-based sequencing and quantitative PCR (qPCR) were performed to describe bacterial diversity and quantify specific microbial (bacterial and archaeal 16S rRNA genes, Enterococcus spp., and a phage of Aerococcus viridans) and animal (swine and poultry DNA) markers. No significant differences in OTUs abundance and diversity between indoor bioaerosols and their corresponding fan exhaust samples were observed. There were also no significant differences between an indoor and its corresponding fan exhaust air sample when comparing OTUs relative abundance and their presence-absence. Similarly, concentrations of bacterial 16S rRNA genes in indoor samples (10&lt;sup&gt;6&lt;/sup&gt;-10&lt;sup&gt;8&lt;/sup&gt;) did not significantly differ from those found in samples collected at the fan exhaust (10&lt;sup&gt;5&lt;/sup&gt;-10&lt;sup&gt;8&lt;/sup&gt;) for both PFBs and BCBs. Strong correlations were observed between sampling sites for Archaea, Enterococcus, and A. viridans phage concentrations while poultry and swine DNA concentrations at fan exhausts did not correlate with indoor levels. All investigated markers were detectable at fan exhausts, even at low indoor concentrations (10&lt;sup&gt;2&lt;/sup&gt;-10&lt;sup&gt;3&lt;/sup&gt;). Our study suggests that air sampling at the fan exhaust of barns provides a representative picture of the indoor bioaerosols both for bacterial diversity and barn-specific indicators when the fans are in use. This method appears promising for characterizing indoor air quality based on emissions and could be highly valuable in ","PeriodicalId":45344,"journal":{"name":"Journal of Agricultural Safety and Health","volume":"31 2","pages":"121-132"},"PeriodicalIF":0.9,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144838124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing regression models for predicting the static friction force of tractors demonstrate inadequate accuracy, necessitating further refinement. Therefore, this study was conducted to improve the accuracy of the maximum static friction force prediction model developed in a previous study for tractors with a front-end loader. As a result of measuring the maximum static friction, it tended to increase as the rear ballast weight increased and to decrease as the payload increased. The accuracy of the regression models in this study was significantly improved compared to that in previous studies. The regression model that used the reaction forces of the front and rear axles as variables exhibited the highest accuracy, followed by the model using the rear axle reaction only. The reaction force of the rear axle had a greater effect on the maximum static friction than that of the front axle.

Body composition, including skeletal muscle and fat percentages, is critical for work ability (WA), influencing strength and endurance. The current study investigated the association between WA and body composition among Thai farm workers. A cross-sectional study was conducted among 126 corn farm workers in Nan Province, Thailand. Data were collected using a structured questionnaire covering demographic characteristics, health behaviors, and WA (assessed using the Work Ability Index, WAI). Body composition variables, including body mass index, body fat percentage (BFP), subcutaneous fat percentage (SFP), and skeletal muscle percentage (SMP), were measured using a body composition analyzer. The association between body composition and WA was analyzed using multiple regression analysis to control the effects of confounding factors. The average WAI score was 37.3 (standard deviation = 5.6), with 42.9% of participants classified as having good WA. A significant positive association was found between WA and SMP (whole body, trunk, arms, and legs) (p < 0.001). Conversely, WA was negatively associated with SFP (trunk and legs) (p < 0.01), as well as SFP (whole body) and BFP (p < 0.001). The findings suggest that maintaining a higher SMP and reducing excess fat, particularly subcutaneous fat, can enhance WA in farm workers.
