Article:

Agriculture remains a highly dangerous industry for occupational health and safety. This study sought to understand the perspective of agricultural professionals with respect to the current state of the industry, challenges, and opportunities relevant to occupational health and safety. Additional questions related to the COVID-19 pandemic emerged in the findings as well. Eleven industry professionals were interviewed, and the transcripts were qualitatively analyzed for emergent themes following a constant comparative method. Three themes emerged in our findings: a description of the current state of occupational health and safety in the agricultural industry, barriers to improving occupational health and safety, and enablers of occupational health and safety. Each theme contained subthemes. The description of the industry encompassed regulations, inherent danger, and attitudes and education. Barriers included education, health care access, logistics, discrimination and cultural competency, economic considerations, and the labor contracting system. Enablers included education, regulations, and health care and prevention. These findings are consistent with existing literature, revealing interconnected and overlapping challenges and opportunities. Further research is recommended with a broader sample of participants, especially farmworkers.
