One of the duties of Port Health Services is to carry out inspections of vessels for the presence of any rat infestations. If the presence of rats is detected, the Health Authority will require that steps are taken by the Shipping Agent, on behalf of the owners and at his expense, for a disinfestation to be carried out under its direction. A Deratting Certificate will only be issued by Port Health Services if the deratting has been carried out to its complete satisfaction.
