Introduction
Eggs are a staple ingredient in many households, enjoyed for their versatility and nutritional value. However, it’s essential to be able to identify bad eggs to avoid foodborne illnesses. Spoiled eggs can be difficult to detect just by looking at them, which is why we’ve put together some tips and tricks to help you know if an egg is bad.
Look for Visible Damage
One of the easiest ways to identify a bad egg is by looking for visible damage on the eggshell. Cracks on the eggshell can allow bacteria to enter the egg, which can cause it to spoil. When inspecting eggs, it’s crucial to handle them delicately to avoid causing any damage to the shell.
Tip: Look for any cracks, stains, or discoloration on the eggshell. If you notice any, it’s best to discard the egg.
Check the Expiration Date
Check the expiration date printed on the egg carton to ensure freshness. The use-by date can help ensure that the egg is still edible. Eggs are typically good for up to 4–5 weeks after the packing date if they have been consistently refrigerated.
Tip: Always check the expiration date before purchasing eggs and again before consuming them.
Clean the Eggshell and Perform a Float Test
Cleaning the eggshell can help identify any spoilage on the exterior. If an egg has spoiled, there may be discoloration on the shell or a strange odor. A simple yet effective way to tell a fresh egg from a bad one is using a float test. Place the egg in a bowl of water; if it sinks to the bottom and lays flat, it’s fresh. If the egg stands upright or floats to the surface, it’s best to discard it.
Tip: Be sure to clean the eggshell and dry the egg before performing the float test.
Sniff Test and Texture Check
Smelling the egg can help identify off-putting odors. A bad egg has a distinct odor that is hard to ignore. Additionally, the texture of the egg can indicate spoilage. Fresh eggs have a thick, sturdy texture, while bad eggs will have a runny consistency.
Tip: Always sniff the egg before using it in any recipe. Also, be sure to inspect the egg’s texture carefully.
Use a Digital Thermometer
A digital thermometer can help check the internal temperature of the egg, which is especially helpful when preparing egg dishes like custards, quiches, and sauces. Cooking eggs to the correct temperature is essential to eliminate any harmful bacteria and ensure that the egg is safe for consumption.
Tip: Use a food thermometer to check if eggs have been cooked to a minimum of 160°F (71°C).
Conclusion
Identifying a bad egg is crucial for maintaining good health and avoiding food poisoning. Always handle eggs with care and thoroughly check for visible damage, expiration date, perform float and sniff tests, and, if necessary, use a digital thermometer. It’s essential to be thorough when checking eggs before consuming them, as eggs are a staple ingredient in many kitchens.
