I currently ran into an issue where in a formulation trial I had 1 of 4 products fail an already validated hold time. The issue I am having is that the product was extremely near a 5 log reduction, but simply did not meet. Additionally, it was only one lot of the same formulation that went rogue (ran in duplo).
It would appear that it was a formulation issue (products have yet to hit market, still hand preparing product) imho. What would be the proper decision on moving forward? Would you re-test?
Customer has put an extremely tight time constraint on this as well but we all know you can't rush good science...
