Or. Admin. Code § 603-022-0305 - Quality Grade Standards
(1) AA
Quality. The shell must be clean, unbroken, and practically normal. The air
cell must not exceed 1/8 inch in depth, may show unlimited movement, and may be
free or bubbly. The white must be clear and firm so that the yolk is only
slightly defined when the egg is twirled before the candling light. The yolk
must be practically free from apparent defects.
(2) A Quality. The shell must be clean,
unbroken, and practically normal. The air cell must not exceed 3/16 inch in
depth, may show unlimited movement, and may be free or bubbly. The white must
be clear and at least reasonably firm so that the yolk outline is only fairly
well defined when the egg is twirled before the candling light. The yolk must
be practically free from apparent defects.
(3) B Quality. The shell must be unbroken,
may be abnormal and may have slightly stained areas. Moderately stained areas
are permitted if they do not cover more than 1/32 of the shell surface if
localized, or 1/16 of the shell surface if scattered. Eggs having shells with
prominent stains or adhering dirt are not permitted. The air cell may be over
3/8 inch in depth, may show unlimited movement, and may be free or bubbly. The
white may be weak so that the yolk outline is plainly visible when the egg is
twirled before the candling light. The yolk may appear dark, enlarged and
flattened, and may show clearly visible germ development but no blood due to
such development. It may show other serious defects that do not render the egg
inedible. Small blood spots or meat spots (aggregating not more than 1/8 inch
in diameter) may be present.
