Only chemicals approved as pesticides by the appropriate regulatory agency should be used for pest control in a food plant. "Restricted Use" pesticides should only be used with the required supervision and "General Use" pesticides should only be used by personnel with the required training. Every effort should be made to prevent the likelihood of contamination of food and food contact surfaces with pesticides. All pesticides and all pesticide application equipment must be clearly identified with labels and stored in a protected, locked area far removed from food processing areas and storage areas fo raw materials, ingredients, packaging materials, cleaning materials and products.
