What does it mean if an egg floats?

In this brief guide, we’ll explore the search query:” what does it mean if an egg floats?” Also, we’ll explore what other signs denote that an egg has spoiled, what the dangers of eating rotten eggs are, and how to properly store eggs. 

What does it mean if an egg floats? 

If an egg floats, it means that it has most likely spoiled. This is because some of the biomolecules, such as fat and proteins, will have begun to denature (break down) and form smaller molecules that are less dense than water. Also, the air pocket at the base will have expanded, further diminishing its density. 

As a result, the egg will float when it is submerged, and spoilage will be irreversible, regardless of how it is stored from that point on. 

Eggs that float should be discarded. They should not be fed to pets or as slop, as there is a risk of them bearing disease-causing microbes, such as salmonella. 

We encourage our readers to properly store their eggs, especially if they buy in bulk. This can help them reduce waste, as well as save money. 

What are the signs of a spoiled egg? 

The signs of a spoiled include floating when submerged in water, having an off texture (too watery), giving off foul smells, and being discolored. 

Eggs with cracked shells spoil more easily, as microorganisms that cause spoilage can more easily find their way inside the shell, and rapidly cause spoilage of the egg whites and yolks. 

To avoid this, we encourage our readers to refrigerate their eggs or freeze them, especially if they’ve bought a volume of eggs that won’t readily be consumed. 

Our readers should therefore inspect every egg, they intend on cooking with, to make sure that the yolk and white are of optimal quality, and cause no adverse effects on their health. 

What are the dangers of eating spoiled eggs? 

The dangers of cooking with spoiled eggs include a heightened risk of food poisoning, which can be transmitted to groups that are especially at risk. 

Salmonella bacteria may be present in higher levels in eggs that have spoiled, and these may trigger severe symptoms of food poisoning such as vomiting, diarrhea, abdominal aches, dehydration, and fevers. 

Groups that are especially at risk when suffering from these symptoms include young children, pregnant and breastfeeding women, the elderly, and those who are immunosuppressed. 

Symptoms may be treated with supplemental electrolytes and antibiotics. In severe cases, they may require intravenous fluid placement.  

If you’re suffering from any or all of these symptoms, we encourage you to seek out medical assistance. Prescription medication (such as antibiotics) may be necessary, along with other therapies to hasten your recovery. 

We urge our readers not to self-medicate and to visit a certified medical professional if their symptoms are severe. 

How can I properly store eggs? 

To prolong their shelf life, eggs can be stored in a pantry if they’ll be used or otherwise consumed shortly. 

Eggs that have been bought to last for a certain period (such as a week or so) should be stored in refrigeration to keep microbes from growing in and on them. They should be stored in the center of the fridge and placed near the cooling sources, to avoid temperature fluctuations when the fridge is opened and closed. 

Alternatively, eggs can be frozen. Storing eggs at sub-zero temperatures greatly extends their shelf life. 

On average, eggs have a shelf life of up to five weeks after they’ve been placed in refrigeration, whereas frozen, they can be preserved for up to one year. 

Freezing eggs can be done individually and in bulk, though the former is often preferable, for rationing. 

Eggs that are going to be frozen can be whisked together before being emptied into an ice cube tray compartment. From here, an ice cube tray filled with eggs can be flash-frozen. This means that it’s placed in the freezer until the eggs have solidified, at which point they can be transferred to a heavy-duty freezer bag, and stored for up to a year in the freezer. 

Alternatively, many eggs can be whisked together and frozen in bulk within a heavy-duty freezer bag, though they can only be defrosted once, and must be used in their entirety: defrosted eggs can keep for up to 5 days in refrigeration and may be difficult to ration. 

We encourage our readers to mull over which storage option best suits their needs, and to observe all proper guidelines for safeguarding their health, and the quality of their food.
