Eggs are a natural product, so it’s no surprise that they don’t always look perfectly uniform. Cracks, blemishes, and imperfections are common, but what do they really tell us about an egg’s quality and safety? Understanding these small details can help you decide which eggs to use and how to handle them.

Cracks: A Real Concern

Cracks in an eggshell are the most serious imperfection to watch for. The shell is the egg’s first defence against bacteria. When it’s cracked, harmful microorganisms like Salmonella can easily find their way inside.

• Hairline cracks are very thin and sometimes hard to see. If found early, these eggs can still be safe if refrigerated promptly and thoroughly cooked.
• Deep cracks, however, mean the egg should be discarded. The risk of contamination is high, especially if the egg has been sitting out.

If you accidentally crack an egg while collecting or handling it, it’s best to use it right away in cooked dishes, where heat will kill any potential bacteria.

Blemishes: Mostly Cosmetic

Unlike cracks, most blemishes are harmless. Common blemishes include:

• Calcium deposits, which appear as rough patches or bumps on the shell.
• Pigment spots or speckles, usually seen on brown eggs, caused by natural pigment variations.
• Dirty shells, resulting from nest debris or droppings, can often be washed off gently.

These blemishes do not affect the egg’s taste or nutritional value. However, excessive cleaning can remove the egg’s natural protective coating (called the “bloom”), slightly shortening its shelf life.

Other Imperfections

• Thin-shelled eggs can occur due to a hen’s diet or age. They are more fragile but still safe if handled carefully.
• Misshapen or wrinkled eggs often result from stress or illness in the hen. They are still edible if the shell is intact.
• Shell-less eggs should be used immediately if fresh, as they are highly vulnerable to contamination.

Cracks should always be treated with caution, but blemishes and irregularities are usually no cause for concern. Eggs are a natural product, and small imperfections are part of their charm. By inspecting your eggs carefully and handling them properly, you can enjoy their fresh, wholesome benefits — imperfections and all.
