§ Mr. ButlerTo ask the Secretary of State for Health whether he will make a statement about the role of cockroaches in the spread of human disease.
§ Mr. FreemanIn the terminology of communicable disease, a "carrier" is a person or animal that harbours a specific infectious agent in the absence of discernable clinical disease and serves as a potential source of infection. Cockroaches may become carriers and can be deleterious to human health by mechanically transmitting infection. For example, a cockroach that has been in contact with infected material and then comes into contact with food can contaminate food. The Department is sponsoring research into the effectiveness of hydromethylnon in eradicating cockroaches and the development of juvenile hormone analogue which would aim to prevent the development of cockroaches to the adult stage. The results of this work are expected by the end of 1989.
