Every restaurant and cafe in NSW will receive a random health inspection in the next 12 months after Government health bosses were left reeling by the results of their latest food safety crackdown.

Health and safety inspectors have issued 160 fines in four weeks. The NSW Food Authority launched a "name and shame" website in July to try to improve hygiene standards. Department officials expected to uncover kitchen nightmares but did not envisage dishing out 1000 fines to 600 businesses in 10 months.

The name-and-shame list is updated on Tuesdays and has had more than 1.5million hits since it was put on the Internet.
