You should note the odor coming from the case and packing material
immediately upon opening the sample shipping containers. Off-odors
(especially musty odors) should be noted.
b. For wholesale grade shell eggs, select either a whole case or half a case of
eggs, depending on which method of weighing is to be used. Predetermine a sampling
pattern before sampling. If only a half-case of eggs is to be weighed, determine in a
random manner whether the marked and/or unmarked end of the first sample of the
container is to be used. Alternate compartments on succeeding sample containers
must be used. (Additional information on selecting samples is provided in Lesson 4 of
2-15. DETERMINING ACTUAL NET WEIGHT OF A CASE OF SHELL EGGS
You must determine that the actual weight of a case of shell eggs is as specified
in the inspection data packet. You are not responsible for counting the number of units
delivered. This is done by an accountable individual.
a. Test Accuracy of Scales. For additional information, see Subcourse
MD0704, Inspection Records and Reports.
(1) Regular platform scales are normally used for weighing. However, a
smaller case-weighing scale, included in the egg inspection kit, may be used if the
platform scales are not available. Platform scales are preferred since the
case-weighing scales can not be sealed.
(2) When case-weighing scales are used, test their accuracy with the
(a) Turn the adjustment knob (usually located at the foot of the scales)
so that the dial is set at zero.
(b) Place test weight(s) on the scale (20-25 pound weight is
(c) If scales are off by more than 1/4 pound, turn the adjustment knob
until the desired reading is obtained.
b. Determine Actual Net Weight of Consumer Grade Shell Eggs.
Remove a 15-dozen-egg sample from the container.
