TUCKER, Ga. — Heat stress is a persistent occupational hazard across many sectors of the U.S. economy, including the poultry and egg industry. From live production, feed mills and hatcheries to processing plants and egg-grading facilities, employees may be exposed to elevated temperatures, high humidity and physical exertion. As climate patterns shift and extreme heat events in spring and summer become more frequent, mitigating worker heat stress remains a critical component of workplace safety.
Heat stress occurs when the body cannot adequately cool itself, leading to a range of health effects — from fatigue and dehydration to heat exhaustion and potentially life-threatening heat stroke. In poultry and egg facilities, common risk factors include high ambient temperatures caused by summer weather or heat-generating equipment, elevated humidity in production houses and scalding areas, and physically demanding tasks such as lifting, catching, processing and sanitation work.
Engineering controls are often the most effective long-term method of reducing heat exposure. Across the industry, these measures may include upgraded ventilation systems in production houses and processing areas, fans to improve air circulation, properly functioning exhaust systems in high-heat zones such as broiler, scalding and rendering areas, shielding or insulating heat-producing equipment and scheduled maintenance to ensure motors and compressors do not overheat.
The industry has implemented administrative strategies that are essential for environments where heat generation cannot be fully engineered out. These strategies include implementing structured breaks based on temperature, humidity and workload, and job rotation for employees between hot and cooler tasks to limit cumulative exposure. Access to cool, potable water close to all work areas and education on limiting caffeine and sugary drinks during hot shifts. Acclimatization programs are another important practice, allowing new or returning employees to gradually adjust to hot working conditions while being closely monitored.
Training and awareness are vital to ensure employees understand the risks of heat stress and know how to respond. Workers should be trained to recognize signs and symptoms of heat-related illness, understand when medical intervention is needed and support co-workers by identifying early warning signs. Education should also reinforce the importance of hydration, rest and acclimatization.
As the Occupational Safety and Health Administration evaluates the need to create a national standard for heat stress prevention both indoors and outdoors, its National Emphasis Program underscores the importance of written heat illness prevention plans. Effective plans should include heat exposure assessment and monitoring procedures, as well as clear roles for supervisors and safety personnel. Emergency response and medical protocols are necessary and should be continuously improved when incidents arise. A clear focus should be placed on weather-based action thresholds, with a focus on increasing break periods, fluid consumption and worker acclimatization.
Heat stress mitigation is both a worker safety priority and a business necessity. By combining engineering solutions, administrative controls and strong training programs, employers can reduce heat-related injuries and illnesses, support productivity and strengthen a culture of safety in the poultry and egg industry.
