Structured Hygiene Survey: What do bacteria and germs look like?

Fully geared with a complete swab kit and safety gloves, Initial Hygiene Specialist, Sandy is ready to assume the role of a “science investigator” with a Lumitester measuring instrument to test for bacteria and germs evidence.

The Structured Hygiene Survey (SHS) is an important milestone for her client. The office houses more than 100 employees, this means regular and frequent interaction could potentially risk cross contamination among each other. So what do bacteria and germs look like and where are they? The SHS helps to answer.

Today, Sandy will help to shed some light on bacteria count in common areas, let’s move on to find out!

The washroom main door handle is a high usage and common touchpoint. Sandy whips out the kit’s swab stick, wets the bud tip and starts on the door handle by swabbing across the surface. The stick returns into the kit and the operation is completed with the push-in swab and mix with the reagent. To take the reading of bacteria count per square inch (BPSI), the entire swab kit is then inserted into the Lumitester measuring instrument. Find out the results below:  

(A reading more than 200 BPSI indicates bacteria build-up and surface contamination.) 

  • Washroom main door handle @ 313 BPSI 
  • Toilet seat cover @376 BPSI 
  • Toilet cubicle door knob @ 502 BPSI 
  • Toilet flush button/ handle @ 729 BPSI

Now you know- most of the spots in a washroom are germy spots you would not want to touch with bare hands! 

Tip: A Hand Sanitiser can be installed outside the washroom to sanitise your hands after in contact with the door handle.

Did you know? A contaminated surface with bacteria build-up poses health risks to people as the harmful bacteria can lead to the following:

  • Food poisoning 
  • Throat infections 
  • Abdominal pain and diarrhoea 
  • Hepatitis A 
  • Common cold & flu germs

Tip: A simple sanitation on the toilet seat cover with a Toilet Seat Cleaner is able to reduce the BPSI to under 100!

With employees visiting the toilets three times daily on average, that is about 1,200 times exposure to cross contamination per year and thus increasing the potential for illness in the office.
