The owner of two Woden sushi shops has been fined $41,000 for serious health safety breaches.

Raids on the Sizzle Bento and Roll-A-Sushi, owned by parent company World Fashion Food Pty Ltd, uncovered a cockroach infestation, a dishwasher that recycled dirty water, and food being defrosted and stored on the floor.

World Fashion Food Pty Ltd was sentenced by Special Magistrate Margaret Hunter in the ACT Magistrates Court on Monday on 11 criminal charges for the breaches of food standards.

Court documents said health authorities discovered a cockroach infestation, a dishwasher that repeatedly recycled dirty water, and an overheated display cabinet during raids at the now closed Sizzle Bento store in Woden Plaza in May 2011.

Cleanliness and food storage breaches were again detected during a second inspection in September 2011.

Pictures tendered in court showed food safety inspectors encountered cockroaches in the food preparation area.

Court documents said the sushi display cabinet had been set at about 10 degrees, instead of the recommended 5 degrees or less.
