Section II. SAMPLING DATA
DETERMINING LOT SIZE
How the lot size is determined is dependent on the number of dozens of eggs
being delivered. This information is extracted from the IDP. The IDP usually stipulates
either wholesale grade troop issue or consumer grade resale shell eggs.
a. Wholesale grade shell eggs are normally used for troop issue feeding and
come 30 dozen to a case. The shipping container is divided into two compartments with
each compartment containing six layers (see figure 2-1), with one tray per layer. There
are 30 eggs on each tray. Each compartment will have seven trays, six will contain
eggs and the top will be empty and provide protection. An egg tray is illustrated in
b. Consumer grade shell eggs, normally used for resale in commissaries, come
in 15, 18, 24, or 30 cartons of eggs per container. The eggs are packed one dozen per
c. The lot size is always expressed in cases (a case is 30 dozen or 360 eggs)
except when temperature requirements are being given. When temperature
requirements are stated, the lot size is expressed in terms of shipping containers.
(1) To convert the number of eggs (in dozens) to cases, divide 30 into the
total number of dozens of eggs being inspected. See figure 2-3 for the multiplication
factors provided in subsection 218.8 of DPSC Manual 4155.6.
(2) To convert the number of eggs (in dozens) to shipping containers, divide
by number of dozens per shipping container.
