In response to a complaint made by Kevin Fletcher of Berrimah Prison with regard to troublesome mosquitoes in the female section of the prison, an inspection was made of the effluent ponds and drainage system at the
adjoining Angliss Abattoir. Two officers of the Medical Entomology Branch made contact with Mr Donald Hoare, the proprietor of Angliss Abattoir, for permission to inspect the effluent system, and subsequently, in the company of Mr Glen Storer (Abattoir Manager), a larval survey of the effluent pond and the associated drain was conducted.
