Although not poisons, birds, especially wild birds, can carry diseases that can infect humans. (When humans contract disease from animals it is called a Zoonotic disease.) For that reason, general precautions should be taken to avoid contamination by viruses, bacteria, or other disease through handling of wild birds, inhaling airborne contaminates, or touching items with their droppings on them. Always wash hands with soap and water after handling birds, their food or water dishes, or items contaminated with their droppings. Never touch dead wild birds without gloves and be careful not to inhale dust or particles from them.
According to the US Government's Center for Disease Control (CDC) some of the more common diseases that humans can contract by contact with birds are:
Chlamydia psittaci Infection (psittacosis): A bacterial disease associated with pet birds, including parrots and parakeets.
Cryptococcus Infection (cryptococcosis): A fungal disease associated with wild-bird droppings, including those from pigeons.
Salmonella Infection (salmonellosis): A bacterial disease associated with many birds, especially chickens, baby chicks, and ducklings.
In addition, there are over 60 transmissible diseases like the ones listed above that are associated with wild birds (including but not limited to pigeons, geese, starlings, and sparrows), some of these diseases are fatal. More examples of these are: Histoplasmosis, Candidiasis, St. Louis Encephalitis, E.Coli,Campylobacteriosis, New Castles Disease, Allergic Alveolitus, Mycobacteriosis (Avian Tuberculosis), Influenza, Giardia, and Cryptosporidiosis.
Also, there are parasites that can be harmful to humans and to other household pets such as: Bed bugs (cimex lectularius); Chicken mites (Dermanyssus gallinae) that are found on many common backyard birds, not just chickens, and which are known to carry encephalitis, acariasis and mite-induced dermatitis; Yellow mealworms (Tenebrio molitor) found in pigeon nests and can cause intestinal canthariasis andhymenolespiasis.
