Garri production stands as a vital economic endeavor in Nigeria, with the well-being of local producers raising concerns regarding health and safety. This study focused on evaluating the prevalence of heat stress among Omoboriowo local garri processing producers in Ifon Osun, Orolu Local Government. Employing a descriptive survey research design, the study included a sample size of 30 garri processing producers, and data were collected through a questionnaire. Results indicated that all respondents (100%) recognized the potential for high temperatures to induce heat stress, leading to heat stroke. Furthermore, a majority of participants (93.3%) reported observing symptoms of heat stress during garri processing, encompassing fatigue, headaches, dizziness, muscle cramps, and nausea. Access to personal protective equipment (PPE) varied, with only 33.3% consistently having access to items like hats, gloves, or cooling vests to alleviate heat stress. Although 70% had received some training on heat stress prevention, only 30% had undergone comprehensive training. The study recommends enhancing the availability and consistent use of appropriate PPE among garri processing producers. Moreover, comprehensive training programs focusing on heat stress prevention and management should be provided to all workers. Introducing regular breaks and rest periods into the work schedule, allowing for cooling down and hydration, and improving ventilation systems in the garri processing area are also recommended.
