Visually clean does not mean clean

I have lost count of the number of times I seen people clean food preparation and hand contact surfaces with lukewarm soapy water. Or I have seen people spray sanitiser on visually soiled surfaces. Yes the end result looks clean, but you will not have killed off any remaining bacteria on the surface and more importantly you will not have removed all of the microscopic food stuffs that bacteria can live off.

Food operators know that cleanliness is essential in all food preparation areas if safe high quality food is going to be produced. But how do you know for sure that you’re cleaning regime is effective? How do you know at a microscopic level that all soils have been removed and that invisible microorganisms that could cause spoilage or illness have been eliminated?

There really is a big difference between “visually clean” and “microbiologically clean”

Food Safety Specialists at RSA Environmental Health are available to answer your questions and help you initiate a process to verify the effectiveness of your cleaning programs.

At RSA Environmental Health we verify cleaning programs effectiveness by using:

ATP bioluminescent monitoring after cleaning to detect remaining food debris; followed by,
Microbial monitoring after sanitizer application to confirm that no viable bacteria remain.
Both techniques are provided either as a one off check or as part of our advisor service program. Note: product testing is not part of the program.

What is ATP Bioluminescence?

ATP bioluminescence is a quick test for determining the relative cleanliness of a surface. ATP is a substance found in all living cells, including food, bacteria, yeast and mould cells. This test uses a device called a luminometer to measure the combined total of organic material (food residues and microbial populations) collected from a swabbed surface.

High values are indicative of high levels of surface organic matter resulting from inappropriate cleaning practices.

ATP bioluminescence results are obtained within seconds. If the reading indicates that a surface is not clean, re-cleaning procedures can be initiated immediately to correct the unhygienic condition.

Microbial Monitoring

Microbial monitoring complements ATP bioluminescence. While a clean surface generally is an indicator of low microbial levels, it is not a guarantee that the area is microbiologically clean. To determine microbial types and/or populations, microbiological analysis of surface areas can also be undertaken.

When Unsanitary Conditions are found

Where unsanitary conditions are identified as a result of ATP bioluminescence or microbial testing, our food safety specialist will either demonstrate or suggest corrective actions appropriate to your operation.
