Even in case you are right and there is no possibility of microbiological growth -> there is no guarantee that the product was not contaminated before! Moreover it can be contaminated during processing steps!
Just think about the PIGS principle!
Presence of Hazards
Introduction of Hazards
Growth of hazards
Survival of Hazards
Maybe G might not be of interest, but are you confident, that you don´t have any problems with the others?
So maybe at least some testing on raw material should be made.
Actually I am shocked that you don´t do any testing O.O
But maybe it´s because I am really sensitive to microbiological hazards due to my products (baby food)......
