Hello every one,
I am trying to validate the sanitation program in our Rice and Grain plant. and we decide to test Enterobacteriaceae as an indicator. when we receive the results from the lab that used the method AOAC 2003.1 (Petrifilm) it was about 100,000/swab. my question is what is the real unite as i have to compare it to UCF/cm^2 and what is the limit for non RTE product (I found only limit for RTE product)
I presume UFC = cfu.
I presume 100,000/swab = 100,000 cfu/swab
A little info is required -
(1) What "item" was swabbed ?
(2) What was the area swabbed ?
(3) If the "item" was a food contact surface (fcs), was the area to be swabbed cleaned/sanitised before testing ?
If the item was a fcs published micro. limits are often based on a just cleaned/sanitised surface . For some data see this Post/thread -
The value for Enterobacteriaceae in cfu/cm2 for a fcs as determined above would normally be low.
