Introduction
When it comes to food safety, eggs are one of the most common sources of bacterial contamination. While there are plenty of ways to tell if an egg has gone bad, it can be difficult to know when to trust your senses and throw out a questionable egg. To help you determine whether an egg is still good or not, this article will explore the various methods for testing freshness. We’ll cover tips for examining the eggshell, performing a floating test, and even taking a sniff test. By the end of this article, you’ll have all the information you need to make sure your eggs are safe to eat.
Examining the Eggshell: Tips for Checking if an Egg is Still Good
The first step in determining the freshness of an egg is to examine the eggshell for any visible cracks or damage. According to the US Department of Agriculture (USDA), “cracks in the shell may indicate that bacteria have started to get inside the egg.” 1 Another way to check for freshness is to look inside the eggshell. If the egg white appears cloudy or discolored, then it’s likely no longer safe to eat. Lastly, you can feel the texture of the eggshell. The USDA recommends “feeling the surface of the eggshell for any slimy or sticky residue, which may indicate spoilage.” 2
Does Your Egg Float? A Guide to Testing If Eggs Are Bad
One of the oldest yet simplest tests for checking egg freshness is the floating test. All you need to do is fill a bowl with cold water and carefully place the egg in the water. If the egg sinks, then it’s still good. But if the egg floats, then it’s no longer safe to eat. According to experts, the reason why eggs float when they’ve gone bad is because “the air cell inside the egg has become larger as a result of gas production.” 3 So if your egg passes the floating test, then you can go ahead and use it for cooking. However, if the egg fails the test, then you should discard it immediately.
“Sniff Test” for Bad Eggs: Learn How to Tell if an Egg is Off
Another method for testing egg freshness is the sniff test. As the name implies, this involves taking a whiff of the egg to see if it has a bad odor. According to the American Egg Board, “a bad egg will give off a sulfur-like smell when the shell is cracked open.” 4 When performing the sniff test, it’s important to be cautious. The USDA advises against smelling the egg directly, as this could expose you to harmful bacteria. Instead, they recommend “sniffing the egg from a distance of about 6 inches away.” 5 If you detect a bad odor, then it’s best to discard the egg right away.
How to Check the Expiration Date of Eggs and Avoid Food Poisoning
It’s also important to pay attention to the expiration date printed on egg cartons. According to the American Egg Board, “Eggs should be used within 3 to 5 weeks of the date they were placed in the carton.” 6 To make sure you don’t miss the expiration date, the USDA suggests writing the date on the egg carton when you first purchase it. This will help you keep track of when the eggs are no longer safe to eat. It’s also important to note that you should never eat eggs that have been left out at room temperature for longer than two hours. Doing so can increase the risk of food poisoning.
How to Tell If an Egg Is No Longer Safe to Eat: Signs to Look For
Finally, it’s important to be aware of the signs that indicate an egg has gone bad. These include a foul odor, a runny yolk, and a slimy or sticky eggshell. If you notice any of these signs, then it’s best to discard the egg right away. Additionally, the USDA recommends disposing of any eggs that have been cracked or damaged in some way. This is to ensure that any bacteria present on the eggshell doesn’t have a chance to contaminate the rest of the egg.
Conclusion
Knowing how to tell if eggs are bad is an essential part of food safety. In this article, we explored the various methods for checking egg freshness, such as examining the eggshell, performing a floating test, and taking a sniff test. We also discussed the importance of checking the expiration date and being aware of the signs of spoiled eggs. By following these tips, you can ensure that your eggs are always safe to eat.
