Program Design
- Is a written environmental monitoring program (EMP) documented with scientific rationale? *
- Is EMP required because a ready-to-eat food is exposed to the environment before packaging? *
- Are hygienic zones 1-4 defined and mapped across the facility? *
- Is the target organism (Listeria spp., Salmonella, or indicator) defined for each area? *
Sampling Plan
- Are sampling sites, zones, and frequencies defined in a documented schedule? *
- Are random and rotating sites included to avoid predictable sampling? *
- Is sampling conducted during production (several hours in) rather than post-sanitation only? *
- Number of environmental sites sampled per period
Testing & Laboratory
- Is testing performed by an accredited laboratory using validated methods? *
- Are analytical methods and detection limits appropriate for the target organism? *
- Are results trended over time to detect harborage sites? *
Response to Positives
- Is a documented corrective action / seek-and-destroy procedure triggered by a presumptive positive? *
- Is vectoring (intensified sampling around the positive) performed after a Zone 2/3 positive? *
- Are procedures defined for finished-product hold/testing after a Zone 1 positive? *
- Is root-cause analysis conducted for recurring positives? *
- Date of most recent presumptive positive investigation
