Footpad dermatitis (FPD) in poultry, also known as pododermatitis, causes sore, inflamed footpads and lesions, affecting mobility. It often stems from damp, unsanitary litter. With chicken paws in high demand globally, now the third most valuable part of the chicken after the breast and wings, FPD-damaged paws concern the poultry industry due to impacts on animal welfare, product quality, and food safety. Preventing FPD through a dry, clean environment is crucial for maintaining bird health and farm productivity.

The primary factor that drives footpad dermatitis in broiler flocks is damp bedding. Litter moisture levels are influenced by variables such as drinker line calibration, feed formulation, ambient barn temperature and humidity, bedding material and depth, and the flock's gastrointestinal health.
Footpad dermatitis triggers inflammation and lesions on poultry feet and toes, resulting in swelling, discoloration, and tissue thickening. The condition progresses from superficial discoloration to deep skin ulcers, which can ultimately turn into abscesses. Severe cases cause acute pain, lower weight gains, mobility issues, and a higher susceptibility to secondary bacterial infections.
The symptoms of footpad dermatitis are very visual and easy to recognize when inspecting the paws:
