Hi David,
I have also read comment from Mr. Remi. Both methods of ATP and Micro
tests have their own advantages. Most ATP test kit in the market shall be
sensitive enough to reflect the cleanliness of your equipment. Therefore
swab area pass the test by ATP shall be negative or low in TPC test. On
the other hand, swab area does not pass ATP test may not necessarily have
high plate count.
The advantage of ATP test is ATP swab gives you immediate result to allow
immediate corrective action taken (ie. rewash and retest). Whereas micro
test result will not be known until the next day or longer. The corrective
active shall be testing the product and/or recall.
Micro test will tell you the effectiveness of the sanitizing procedure
especially at places where ATP test may be too sensitive especially when
you have older equipments or rougher surface (eg some convayor system)
with biofilms already built up. You can also adjust the threshod for ATP
test for rejection to overcome this problem.
We have tried ATP kits from Charm Science and Neogen and both of them are
good. We are using Neogen's at the present because I like the software
provided for data analysis.
Thanks & Regards,

Microbiological criteria for validation of sanitation
Dear List,
I am looking for some kind of reference sources that specify
microbiological criteria for monitoring/validating sanitation of food
processing sites. Either colony forming units (cfus)/square inch or
luminometer reading values. Also, which method would be the best choice
(microbial swabbing, or ATP presence determination).
Any assistance would be appreciated.
