8. Why does MDA look for Listeria at Retail? Monitor operator s control for risks where RTE PHF are prepared, handled, or stored Prevent adulteration and possibility for adulteration

9. What happens when Listeria is found? Assess whether firm has lost control of their process Bring operator back into compliance adulteration statues Minn. Stat. 34A.02 (Adulteration), Minn. Stat. 31.02 (Prohibited Acts), and Minnesota Administrative Rule Chapter 4626.0015 (Food Safety under Food Code) Corrective Action Plan best guidance for accomplishing this

10. Firm Actions: Cleaning, CAP, and Verification Intensely clean and sanitize Assess causes and contributing factors Write a Corrective Action Plan (CAP) Cleaning and Sanitizing how? where? Equipment and employee flow Repairs to equipment or structure Employee training Verify that actions have been effective = firm sampling

11. MDA Actions Provide guidance but not act as their QA Review CAP Confirmatory sampling Visit operator to observe whether control measures were implemented
