Section 583.131 - Terms descriptive of the yolk defined

1. "Blood due to germ development" means blood caused by the development of a germ in a fertile egg to the point where the blood is visible as definite lines or as a blood ring.

2. "Clearly visible germ development" means development of a germ spot on the yolk of a fertile egg that has progressed to a point where it is plainly visible as a definite circular area or spot with no blood in evidence.

3. A yolk has "definite but not serious defects" if it shows definite spots or areas on its surface but with only a slight indication of germ development or other pronounced or serious defects.

4. A yolk is "enlarged and flattened" if the membranes and tissues of the yolk have weakened and moisture has been absorbed from the white to such an extent that the yolk appears definitely enlarged and flat.

5. A yolk has "serious defects" if it shows well-developed spots or areas and other serious defects such as olive yolks which do not render the egg inedible.

6. "Outline fairly well defined" means the outline of a yolk is discernible but not clearly defined as the egg is twirled.

7. "Outline plainly visible" means the outline of a yolk is clearly visible as a dark shadow when the egg is twirled.

8. "Outline slightly defined" means the outline of a yolk is indistinctly indicated and appears to blend into the surrounding white as the egg is twirled.

9. A yolk is "practically free from defects" if it shows no germ development although it may show other very slight defects on its surface.
