  • Closed Techniques (Cleaning-in-place (CIP) systems):
    • Single use CIP systems.
    • Multiuse/Reuse CIP systems.
  • Reuse CIP system: Cleaning/detergent solutions are reused.
    • Automatic mode (pre-rinse, detergent recirculation, acid recirculation, sterilant recirculation, hot water sterilisation, final water rinse).

Proper Storage of Food & Chemical Agents

  • Food placement: Facilitate cleaning, maintain wholesomeness, and implement stock rotation (e.g., date codes).
  • Separate storage: Food, raw material, & chemical agents. Use safety symbols, ventilated, spill containment. Maintain secure storage in original containers, PPE.

Pest Control

  • Pests: No pests in food plants (affects product, leads to possible recall).
  • Control Measures:
    • Habitat Elimination.
    • Exclusion (eliminate access to food, warmth, moisture).
    • Sanitation (regular cleaning).
    • Extermination (traps, baits).
  • Concerns: Insects, Rodents, Birds (disease-carrying microorganisms).
