Third Party Testing Validates Effectiveness of COVID-19 Sanitation



Testing and documentation are central elements of our approach at PSSI. Not only as part of our daily sanitation process and reporting, but it is a major cornerstone in how we hold ourselves accountable and continue advancing the science behind our products and sanitation processes. Specifically in the case of the COVID-19 outbreak, our team felt it was critical to test our sanitation measures against the SARS-CoV-2 virus to validate they are effective in removing and preventing the virus across non-production areas within a food facility.

Testing Plan

PSSI partnered with a leading food processing facility to conduct detailed, widespread testing. The testing plan included a random sampling of 36 swabs across high-traffic areas following the Eurofins VIRSeek Instructions specific to COVID-19. This included common area tables, vending machines, restrooms, stairway handrails, breakroom chairs and more. Samplers swabbed 12 locations, each at three time points. Swabs were collected prior to PSSI sanitation, after PSSI sanitation, and after a fogging/misting event with samplers following all safety precautions to aseptically collect swabs for surface testing. The swabs were then shipped to a third-party testing facility.


The screening results from the third-party testing lab showed that the virus was ‘not detected’ in 100% (36/36) of the high-touch-point surfaces sampled. Thus, it was conclusive that SARS-CoV-2 was not found on any high-touch-point surfaces in common areas of the food facility, before or after sanitation measures.
