    Eggs are a staple in many households and are used in countless recipes due to their versatility and nutritional value. However, ensuring the freshness and quality of eggs is crucial for both taste and safety reasons. So, how can you tell if an egg is bad? In this blog, we will explore various methods to help you determine whether an egg is still good or past its prime. By understanding these indicators, you can confidently choose the freshest eggs for your meals.

    Expiration Date

    The first step in assessing an egg's freshness is to check the expiration or best-before date printed on the carton. Egg producers are required to provide this information, and it serves as a reliable guideline for determining the egg's shelf life. If the date has passed, it's a good indication that the egg may be spoiled.

     The Float Test

    One popular method to check an egg's freshness is the float test. Fill a bowl or glass with water and gently place the egg into it. A fresh egg will sink and lay flat on its side at the bottom of the container. However, if the egg stands upright or floats on the water's surface, it has likely gone bad. This occurs because as an egg ages, the air cell inside expands, causing it to float.

    Visual Inspection

    Examining the egg's appearance can also provide clues about its freshness. A fresh egg will typically have a clean and smooth shell, free from cracks or discoloration. However, if you notice any signs of mould, cracks, or leakage, it's a clear indication that the egg is spoiled and should not be consumed.

    Smell Test

    Another way to detect a bad egg is through its smell. Gently crack the egg onto a plate or into a bowl and take a whiff. Fresh eggs typically have a neutral or slightly earthy odour. On the other hand, a foul or sulfuric smell emanating from the egg indicates spoilage, as bacteria inside the egg release unpleasant gases as they multiply.

    The Yolk and White

    By observing the egg's yolk and white, you can gather further information about its freshness. A fresh egg will have a yolk that appears round and stands tall, while the white should be clear and thick. If the yolk is flattened, and the white is watery or runny, it's an indication that the egg is no longer fresh.


    Ensuring the freshness of eggs is essential to maintain their taste, quality, and safety in culinary preparations. By employing a few simple methods, such as checking the expiration date, performing the float test, visually inspecting the shell, sniffing for any off odours, and assessing the yolk and white, you can easily determine whether an egg is bad or still suitable for consumption. Remember to exercise caution when dealing with eggs past their prime, as consuming spoiled eggs can lead to foodborne illnesses.

    With these tips in mind, you can confidently select the freshest eggs for your recipes and enjoy their delightful flavour and nutritional benefits.
