Section 02.02.11.012 - GRADES AND STANDARDS01.Classifications. The following standards, grades and weight classifications are hereby established and adopted. a. Except as otherwise provided in this subsection, all shell eggs sold for human consumption in the Idaho must be designated as one (1) of the following grades: "Idaho Consumer Grade AA," "Idaho Consumer Grade A," "Idaho Consumer Grade B."b. An Idaho producer of shell eggs may sell shell eggs produced on his premises in Idaho directly to consumers at the place of production of the eggs, without grade designations.c. Idaho shell egg producers having three hundred (300) or less hens may sell ungraded shell eggs produced upon their premises to retailers, provided that each carton or other container of ungraded shell eggs sold must be clearly marked "Ungraded" and bear the name and address of the Idaho producer.02.Standards. The following standards for individual shell eggs are used in determining the Idaho consumer grade designation applicable thereto.03.Application. The Idaho standards for quality of individual shell eggs contained in this section are applicable only to eggs that are the product of the domesticated chicken hen and are in the shell.04.Interior Egg Quality Specifications. Interior egg quality specifications for these standards are based on the apparent condition of the interior contents of the egg as it is twirled before the candling light. Any type or make of candling light may be used that will enable the particular grader to make consistently accurate determinations of the interior quality of shell eggs. It is desirable to break out an occasional egg and by determining the Haugh unit value of the broken-out egg, compare the broken-out and candled appearance, thereby aiding in correlating candled and broken-out appearance.05.AA Quality. The shell must be clean, unbroken and practically normal. The air cell must not exceed one-eighth (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.06.A Quality. The shell must be clean, unbroken and practically normal. The air cell must not exceed three-sixteenths (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.07.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 one thirty-second (1/32) of the shell surface if localized, or one-sixteenth (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 three-sixteenths (3/16) inch in depth, may show unlimited movement, and may be free or bubbly. The white may be weak and watery 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 one-eighth (1/8) inch in diameter) may be present.08.Dirty. An individual egg that has an unbroken shell with adhering dirt or foreign material, prominent stains or moderate stains covering more than one thirty-second (1/32) of the shell surface if localized, or one-sixteenth (1/16) of the shell surface if scattered.09.Check. An individual egg that has a broken shell or crack in the shell but with its shell membranes intact and its contents do not leak. A "check" is considered to be lower in quality than a "dirty."Idaho Admin. Code r. 02.02.11.012
