Cockroaches And Human Health

Cockroaches harbor many species of pathogenic bacteria and other types of harmful organism on or inside their bodies, but they do not transmit human diseases in the same manner as do mosquitoes. They acquire the harmful organisms because of their habit of feeding on almost any type of organic matter, including human and animal wastes. These cockroach-borne organisms can remain viable for a considerable period of time. If the cockroach next visits and soils food intended for human consumption, it is likely that harmful organisms will be deposited on the food. Consuming such food can lead to gastroenteritis, diarrhea, and intestinal infections and pathogenic conditions of other types.

Cockroaches have been shown to harbor pathogenic bacteria belonging to the genera Mycobacterium, Shigella, Staphylococcus, Salmonella, Escherichia, Streptococcus, and Clostridium. They also harbor pathogenic protozoa in the genera Balantidium, Entamoeba, Giardia, and Toxoplasma, and parasites in the genera Schistosoma, Taenia, Ascaris, Anclyostoma, and Necator. From these lists of organisms it is clear that cockroaches are important as potential disease vectors.

Cockroaches are also important because people can become allergic to them, especially under conditions of constant exposure. These reactions usually involve the skin and/or respiratory system. Studies have shown that people who exhibit skin or bronchial responses to cockroaches have elevated levels of cockroach-specific antibodies. These responses can be severe and may require treatment. The species most commonly involved in producing allergic reactions are the German and American cockroaches.
