Which factor assesses the shell's cleanliness, strength, and shape?

• A. Factor 2 - Air Cell
• B. Factor 1 - Shell
• C. Factor 3 - Whites/albumen
• D. Factor 4 - Yolk

Answer: (B)

Shell quality is evaluated by looking at the outer covering of the egg. The key aspects are cleanliness, strength, and shape. Cleanliness checks for dirt, stains, or debris that could harbor bacteria and indicate poor handling or storage. Strength measures how well the shell resists cracking during handling, packing, and transport, which is essential for protecting the contents and preventing contamination. Shape looks at uniformity and regularity; irregular shapes can signal development issues or defects and can affect packaging efficiency and consumer appeal. These shell-related checks are distinct from interior attributes: the air cell size relates to freshness and internal air space, the whites/albumen quality concerns thickness and viscosity of the egg white, and the yolk quality focuses on the condition and appearance of the yolk. Therefore, the factor that assesses the shell’s cleanliness, strength, and shape is the shell factor.
