Cockroach food. Causes polio infection!

Polio is an infectious disease caused by a virus that lives in the throat and intestinal tract. It is most often spread through contact with the stool of an infected person and may also be spread through oral/nasal secretions, so unless the cockroach was in an environment of polio infected feces or secretions this transmission won't occur, but if they have been exposed to it then it can be an infected by anything the cockroach touches. Although cockroaches are not usually associated with widespread disease outbreaks, their presence is a sign of poor sanitation procedures and they are known to carry a number of bacteria, which could give rise to serious illness in humans. They may also induce allergies and asthma symptoms in susceptible people.
