House flies, soldier flies and other non-biting flies can and often do become a problem in poultry buildings.
They do not bite or feed on the birds but may carry pathogens because of their habit of feeding on manure, dead birds and other waste materials.
Poultry manure is an excellent development material for fly larvae.
Caged layer operations concentrate a large amount of manure in a relatively small area and therefore create an ideal situation for producing many flies.
Flies and odor coming from poorly managed buildings may result in legal action against the producer.
Science Daily (Mar. 16, 2009) — Researchers at the Johns Hopkins Bloomberg School of Public Health found evidence that houseflies collected near broiler poultry operations may contribute to the dispersion of drug-resistant bacteria and thus increase the potential for human exposure to drug-resistant bacteria.
The findings demonstrate another potential link between industrial food animal production and exposures to antibiotic resistant pathogens.
