GMP Monthly Audit Checklist for Mushroom Packhouse

This GMP monthly audit checklist supports mushroom packhouse operations (e.g., Highline Mushrooms – Crossfield) in verifying food safety and quality controls. It covers the pre-pack area, bulk scaling station, and slicing area, including inspections of ceilings and overheads, ventilation, lighting, drainage, and housekeeping to prevent leaks, dust, and standing water. It checks cross-contamination controls, equipment cleanliness and storage, color-coded cleaning tools, and protection of packaging materials. The checklist verifies product labeling, date coding, pallet wrapping, and storage practices; secure chemical storage and labeling; waste management; and the absence of temporary repairs. It includes documentation and CCP verifications such as metal detection (HM 302), slicer steaming (HM 303), scale verification (HM 304/305/326), knife and cutting board control (HM 308), and traceability and label checks (HM 335). It also prompts weight spot checks, personal hygiene compliance, and training interviews to ensure ongoing GMP compliance and product quality.
