§ 87.23. Terms descriptive of the egg white.

The following terms shall be used in describing the egg white of eggs:
   (1)  Clear. Free from discoloration or from any foreign bodies floating in it. Prominent chalazas shall not be confused with foreign bodies such as spots or blood clots.
   (2)  Firm. (AA quality). Sufficiently thick or viscous to prevent the yolk outline from being more than slightly defined or indistinctly indicated when the egg is twirled. With respect to a broken-out egg, a firm white has a Haugh unit value above 72 when measured at a temperature from 45°F to 60°F.
   (3)  Reasonably firm (A quality). Somewhat less thick or viscous than a firm white. Permits the yolk to approach the shell more closely which results in a fairly well defined yolk outline when the egg is twirled. With respect to a broken-out egg, a reasonably firm white has a Haugh unit value of 60 to 72 when measured at a temperature from 45°F to 60°F.
   (4)  Weak and watery (B quality). Weak, thin, and generally lacking in viscosity. Permits the yolk to approach the shell closely, thus causing the yolk outline to appear plainly visible and dark when the egg is twirled. With respect to a broken-out egg, a weak and watery white has a Haugh unit value below 60 when measured at a temperature from 45°F to 60°F.
   (5)  Blood spots or meat spots. Small blood spots or meat spots aggregating not more than 1/8 inch in diameter, may be classed as B quality. If they are larger or showing diffusion of blood into the white surrounding the blood spots, the egg shall be classified as loss. Blood spots shall not be due to germ development; they may be on the yolk or in the white. Meat spots may be blood spots which have lost their characteristic red color or tissue from the reproductive organs.
   (6)  Bloody white. Eggs with bloody whites or blood diffused through the white shall be classed as loss.
