What exterior grade is assigned to an egg with large calcium deposits and definite ridges?

  1. A

  2. B

  3. C

  4. Loss

The correct answer is: B

The exterior grade assigned to an egg with large calcium deposits and definite ridges is indeed B. This grading system looks at the physical characteristics of the eggshell. An egg is assigned a grade based on its cleanliness, texture, shape, and any abnormalities. The presence of large calcium deposits indicates that the egg has noticeable texture issues, which is a defect that affects the exterior quality. Additionally, definite ridges on the eggshell suggest that the egg has a rough surface. While eggs graded as A are expected to have a smooth and unblemished surface, those with these types of imperfections naturally fall into grade B. Grade B eggs can still be used in certain products, such as commercial baking or processing, where the visual appearance is less critical than it is for eggs sold to consumers directly. Therefore, understanding the impact of characteristics like calcium deposits and ridges is essential for proper grading in poultry assessments.
