A Brisbane fish and chip shop has copped a hefty fine after it was found to be harbouring bugs - and not of the Moreton Bay variety.

The owner of O'Connor's Traditional Fish & Chips at Windsor has been ordered to pay $12,000 for breaching the Food Act after health inspectors found the premises dirty and crawling with cockroaches and flies.

BCC officers found live cockroaches in 10 different locations in the kitchen, including on clean plates intended for use and on an oven hot plate.

The District Court of Queensland heard that Brisbane City Council officers who inspected the shop in April 2013 found live cockroaches in 10 different locations in the kitchen, including on clean plates intended for use and on an oven hot plate.

Cockroaches were also found throughout the kitchen under the food preparation bench, on shelves near plates, on the wall, behind the dishwasher, and on the floor of the shop.
