b. Steps in the Verification of Results of Shell Egg Inspection. The
veterinary food inspection specialist performs verification inspection of the sample eggs.
In summary, this includes candling, assigning each egg a quality score, determining if
an egg is underweight, replacing missing eggs, and examining replacements. The final
step in the process is recording the results of the inspection on the reverse side of the
DD Form 1237. At this time, a specific series of steps are followed.
(1) Verify sample size. The lot size is the number of 30-dozen cases in a
shipment or a 30-dozen case equivalent. Not all shipments are packed in 30 dozen
cases. For example, if a shipping container has 15 dozen eggs in a case, then it is
exactly one-half of a 30 dozen equivalent. The number of cases can be multiplied by
.five to determine the 30-dozen equivalent. There are standard multiplication factors
(found in subsection 218.8 of DPSCM 4155.6) for specific type packs which may vary
considerably as to the number of dozen eggs packed in each case. (See figure 2-3 in
lesson two.) An additional example: for 18 dozen eggs per shipping container, the
multiplication factor for determining the 30-dozen equivalent is 0.6. For the inspection
worksheet, the reference must be to a 30-dozen equivalent. Otherwise, all the
calculations will not be accurate. The number of sample cases from which to select the
100 shell egg sample is shown below. It is based on the number of 30-dozen cases or
an equivalent number to 30-dozen cases.

(2) Verify accuracy of results. Each sample case examined must total 100
eggs. The inspector must add up all entries to the left of the bold line under EGG
QUALITY. This is from A through Loss Other. It is easy enough to make a mistake in
recording, so the results need to be double-checked. Remember that the ADDITIONAL
TOLERANCES are not part of the 100 egg total. B*, Shortage, Underweight Eggs, for
example, are to the right of the bold line and must not be counted for the 100 egg total.
(3) Total each column. Near the bottom of the worksheet there is a place to
add up the number of eggs listed in each column. This must be computed accurately.
For example, all the A quality eggs are added up and a total figure is recorded. The
same is done for all the other columns across the worksheet. Remember that the final
total of B Quality eggs must include the total number of B* eggs.
