Other areas have been contaminated by lagoons overflowing into the surrounding community. CAFO systems are also a large contributor to ammonia being released into the air. It has been reported that up to 70% of Nitrogen from CAFO manure is released into the atmosphere. Airborne Ammonia is a respiratory irritant, mixed with other particulates and can cause a respiratory disease. Complying with the clean water act it would take 1.6 billion dollars to dispose of the manure produced by CAFO systems properly. The communities surrounding these factory farms suffer the most. The smell of feces, contaminated drinking water, Airborne ammonia causing respiratory illnesses. Animals raised in CAFO systems are given large amounts of antibiotics. These animals are frequently sick due to living conditions, resulting in antibiotic resisting pathogens. Some of the bacteria found in CAFO livestock includeing samanela and e coli, can cause food borne diseases in humans. These pathagens can cause millions infected and sometimes causing death. The animals are also injected with growth hormones, a chicken can mature and double its size in 45 days, half the time when matured naturally. Animals injected with these hormons grow so large they have difficulty walking and excising resulting in more
