Environmental Monitoring - Burst Method?


Best Answer nwilson, 23 May 2019 - 07:28 PM

I would assume this would be referencing vectoring, however I would not apply this to an ATP scenario, as ATP is more for sanitation verification than micro-organism detection.  This would be more for say, listeria showing up in a drain and swabbing outward from the drain to see how wide spread the contamination is. 

 

Did this auditor specifically make this call out to the ATP Program?  This also depends on your process (product risk) and how the program is laid out.

Hi All!

 

We recently had our first SQF audit since implementation of ATP swabbing as part of our environmental monitoring program. Our auditor mentioned a "burst method" when retesting after failed results, I looked into it but couldn't find exactly what this is. I asked the ATP test kit company and they haven't heard of it either. I was wondering if anybody has any information about this? Thanks in advance!

I do agree that they are probably referring to vector swabbing or also known as radial swabbing, in which 8-10 swabs which include several zones are performed in a radial pattern outward from the site that tests positive in order to pinpoint the source of contamination.  Each new positive would trigger a new radial pattern until the source can be identified and eliminated.

The "burst" is probably short for "star burst", see -

Is this an audit finding? Did the auditor mentioned something missing/ lacking on your EMP program?

 

If you have a corrective action procedure/ preventive for your failed result, then the auditor might simply gave this as additional information for you.

I'm surprised you were able to just use ATP for enviro swabbing..................................it's not in the spirit of the program...................this is to be directed to PATHOGENS specific to your facility/area/FG/process.......not a general clean/unclean swab


Because we always have is never an appropriate response!

Hi Scampi,

 

Literature opinions can vary although many do agree with you.
