The Scores on Doors program has been invented to assist people in ensuring they are eating at a safe, clean and hygienic eating establishment.

Local restaurants, takeaway shops, bakeries, pub bistros and other food businesses will be required to view their score to show their complyance with NSW food hygiene and safety requirements.

The certificates and adjacent scores will reflect the result of a regular inspections undertaken by council staff.

A restaurant displaying a purple and green poster means it has met minimum safety standards during the last food inspection.

The rating system of Excellent (five stars), Very Good (four stars) and Good (three stars), represent various levels of compliance with the Food Standards Code.

The rating includes such things as food temperature control, food prepared in advance of service, food-handler hygiene, cleaning and sanitisation, as well as pest control.
