Public health inspectors inspect a wide range of food premises to prevent foodborne illnesses. Inspectors also consult with new food premises operators before their businesses open to ensure they are in compliance with all pertinent legislation; respond to and investigate complaints about potential health hazards in food premises; and provide information to the general public on food safety. Inspectors can take enforcement measures, such as issue a ticket or order to close, if conditions at food premise are considered hazardous.

When a recall or advisory has been issued by the Canadian Food Inspection Agency (CFIA) public health inspectors work closely with CFIA and the Ministry of Health and Long Term Care to ensure product is removed from use or sale.
