Currently we are going with USFDA BAM method for E.coli.
For this, we can intertrep the result as <3MPN/g or <10CFC/g.
In that results are same like Absent.
Can we Justify the result, <3MPN/g consider as a Absent/g.
Expertise suggest for this.
I assume you are referring to generic E.coli.
I cannot see any procedural option in BAM for E.coli which offers <10 cfu/g. Please clarify.
I presume the <3 refers to the MPN method for a 3x3 setup, ie For 3 tubes each at 0.1, 0.01, and 0.001 g inocula
In fact you can get even more exact by using more tubes. This is detailed in BAM.
Assuming the above mix, the interpretation (eg see BAM Table1) of <3 MPN/g is - "the outcome with all negative tubes is listed as less than the lowest MPN for an outcome with at least one positive tube".
A similar logic is applied to the other mixes of tubes illustrated in BAM.
So the basic answer to yr OP is No.
