Compositing is limited to 5 or less “like” samples and does not occur in areas with a recent history of positives. A separate sponge is used for each site. Compositing methods are validated to ensure
The EMP takes into account facility conditions. Cold or wet areas are sampled for Listeria spp. In addition program leadership actively seeks the newest information about Lm risk conditions and detection so the EMP is consistent with industry practices.
EMP sites and quantities are selected based on zones, drain locations/quantities, equipment/plant layouts as it relates to Lm risks. Quantities are based on facility size, equipment amount, layout and workflow. A site map is used to define
Where areas are positive (presumptive or confirmed), root cause investigations, mitigation and/or corrective action strategies are deployed. Possible mitigation strategies include re-routing traffic, employment of GMPs, and/or sanitation. In addition, employees are trained to spot
Risk assessment is a key driver for improvements to infrastructure and equipment based on prioritization of equipment and infrastructure condition and contamination related to environmental findings. There is strategic designation of resources to align with
A process with a detailed written plan is established for special events that may require sampling, regardless of time or day. Special event examples may include new/recommissioned equipment, construction events, processing changes, roof leaks, etc.
Sampling materials and test methods are selected based on scientific approaches. Methods are documented, approved and scientifically validated for intended use.
EMP is designed to seek and destroy Lm. The EMP team conducts a robust risk assessment that will lead to the determination of the sampling locations, timing and frequency of samplings. The assessment should include (at
