Apologize for my wording or grammar. I have some question that I confuse to explain to team.
Customer request for coliform testing by use desoxycholate agar that the results will interpret to <10 cfu/g.
But the customer want to show in COA as Negative/0.1 g.
1. I would like to know can I interpret from <10 cfu/g to Negative/0.1 g or not?
If I cannot, Do any one have the correct or standard method that can test coliform
and E. coli to negative/0.1 g.
2. MPN method also, I reported <3 MPN/g to coliform and E. coli in FG products.
But why COA show Negative or Negative in 0.3 g. Is it correct? Or it is not
correct for microbial testing method. But can assume they are the same results for
Please help me to clarify. I would to find the reason that I will explain to customer, R&D or QA.
Thank you everyone in advance for your advice.
