Rodents, insects, flies, cockroaches and other pests are a source of physical and bacterial contamination. The management and the owner have the overall responsibility for the pest control prevention system and should ensure they are implemented correctly. High standards of pest control prevention are important for any business, and  all areas of the business should be included in the prevention of pests program; this includes the food preparation and service areas. If you cannot demonstrate reasonable pest prevention measures  you should seek advice from a pest control and prevention specialist.
