How do you know if your cleaning regimes are effective against SARS-Cov-2? We have developed and validated a test in our
microbiology laboratories which can be used by companies who want to compare the effectiveness of surface cleaning regimes. With rigorous cleaning
regimes regarded as vital in reducing virus transmission, the new test will provide companies with greater confidence in their abilities to clean
The test is ideal for food producers, food service companies, hotels, hospitals, clinics, care homes, the transport sector
(coaches/trains/planes/ships) and any space that holds large numbers of people or has a large footfall. It is also valuable for cleaning service
providers who wish to show the effectiveness of their services.
How does it work and is it safe?
The test evaluates the effectiveness of cleaning and disinfection operations by using a SARS-CoV-2 ‘surrogate’ virus. Our
test uses a surrogate virus that is classified at biosafety level one (BSL-1) and is safe to handle in a range of environments. This means we can
carry out tests in factories, shops, hotels, restaurants, pubs, offices, and warehouses.
We can assess the performance of your cleaning regimes by inoculating your surface with a known amount of the harmless surrogate
virus, that can then be cleaned using your normal procedure. By measuring the level of the virus on a surface before and after cleaning we can
establish the efficacy of the cleaning regime.
Additionally, the test doesn’t look for the surrogate directly – it looks for activity of the surrogate. So, it won’t detect
inactivated virus even if it is there – it will only detect active virus - giving you greater confidence in the results. You can find out more about
how the test works by reading our blog - Does your cleaning kill the COVID-19 virus?
How long does it take?
Once we have carried out the test, we can turn around the results in 3 to 5 working days.
What will my results mean?
The results will show if your cleaning regime is effective or not against the surrogate virus.
