STEP 4: (FOOD) ITEM VERIFICATION USING eLOD50
(EXAMPLE: PROTOCOL 1)
Veri昀椀cation of a Quantitative Method: Neogen
Petri昀椀lm Enterobacteriaceae Count Plate
Since the estimated LOD50 is utilized for both
implementation and (food) item veri昀椀cation, this
same protocol is repeated for each of the (food)
items required to ful昀椀ll (food) item veri昀椀cation. In the
case of this laboratory, this equated to one (food)
item and one “Other” non-food item, completing the
veri昀椀cation process for the one (food) Category and
one “Other” non-food Category claimed to be within
its Scope of Application.
STEP 1: DEFINE THE SCOPE OF THE LABORATORY
APPLICATION
For this example, let’s assume a manufacturing plant
makes ice cream products, infant formula, frozen
pizzas, and refrigerated, ready-to-cook pasta, and it
also collects environmental samples as part of its
environmental monitoring program. Sorting these
items into the 15 food + three other Categories using
