Poultry litter is a valuable source of nutrients for crop production, but its use in agriculture can lead to environmental and public health concerns due to the presence of pollutants, antibiotic-resistant bacteria (ARB) and antibiotic-resistant genes (ARGs). We compared the effect of different on-farm poultry litter composting processes on physicochemical, biological, and toxicological parameters, as well as on the occurrence of antibiotics and resistant Escherichia coli. The composting treatments consisted of passively-aerated piles C:N = 19 (PAC), mechanically-aerated piles C:N = 19 (MAC), and mechanically-aerated piles C:N = 30 (MAC).
