Hi Yettos,
"NFC" = ?
"Disinfection" = ?
"Low Risk" is not necessarily solely quantified by micro. growth potential.
There possibly remains some confusion as to what ATP is typically measuring. See Post 2.
You typically need to establish an operational ATP baseline for what you regard as "adequately" cleaned surfaces as provided by your documented routine cleaning program (= cleaning/sanitising). See Post 2.
If you wish a more quantitative response i suggest you post some data illustrating yr procedure for establishing current baseline limits (= Luminometer calibration ??) and some typical ATP levels for your unclean surfaces.
How do you define a satisfactory, microbiologically clean, surface ?
Hi Charles
NFC - Non food contact surface
Disinfection - Final step of cleaning - spraying 1% disinfectant solution on all cleaned surfaces and allowed to air dry
Calibration of luminomenter is done against the device's manual monthly. No baseline levels were established, clean/unclean limits were taken out of manual.
Effectiveness of cleaning is verified by visual inspection by manager or supervisor and aprox 15 swabs are taken daily for TVC and Enterobacteriaceae with separate schedule for Listeria swabbing.
It seems that I need to establish my own ATP levels for clean/unclean surfaces. This is my first contact with ATP so I am not sure how to proceed. Would you be able to find an example document or procedure? What reduction in ATP are we looking for dirty vs clean surface?
FWIW...most companies with that product would consider it HIGH RISK. Green leafy vegetables have had numerous problems with listeria and e.coli. Think of risk in terms of the risk without doing anything in your facility.
Hi Ryan
I do see your point. I was initially shocked to see current practices, but according to historical micro results production can run up 96 hours without any sanitation, just gross debris removal during wash tank water changes and product changes. For 12 months I have been in my current role we had no major detection in high care areas and in finished product. I have been genuinely surprised to learn it, since hygiene department is severely understaffed and cleaning windows in peak times average less than 2 hours.
