Farm Animal Welfare

Livestock Dust Exposure and Respiratory Welfare

Dust and particulate matter in livestock facilities cause chronic respiratory disease, reducing animal welfare and productivity across millions of animals globally.

Key Facts

Broiler houses can contain 10-50 times WHO safe dust levels
Endotoxins in dust trigger inflammatory lung responses
Chronic respiratory disease is a leading cause of morbidity in pigs and poultry
Ventilation improvements can reduce dust levels by up to 70%
Ammonia and dust together cause additive respiratory damage

Welfare Considerations

Respiratory disease from dust exposure causes sustained suffering — coughing, labored breathing, and reduced activity. Animals in high-dust environments show behavioral signs of discomfort and have significantly reduced lifespans. Welfare-focused management requires monitoring air quality as a key indicator of housing conditions.

What You Can Do

Support farms with independently certified air quality standards
Advocate for mandatory ventilation requirements in livestock housing
Ask producers about dust control protocols
Fund research into low-dust bedding materials
Choose products from farms with published environmental welfare metrics
