if the egg floats, it is spoiled, it is dangerous to eat such a product.<\/li>\n<\/ul>\nWhy does a rotten egg float in water?<\/h4>\n
The egg is not airtight. There are pores in the shell for the embryo to breathe. But, in addition to oxygen, various microorganisms also enter the egg, which, under certain conditions, start putrefactive processes. As a result, gases are released, which raise the egg to the surface of the water.<\/p>\n
6 Visual assessment<\/h4>\n
It is difficult to determine by its appearance whether the egg is fresh or not, since rotten eggs practically do not have any signs. You need to carefully look for cracks, powdery deposits on the egg. If the egg is broken, you need to look at the protein to see if there is a change in color (pink, black, green, blue). In this case, the egg must be discarded. If the protein is normal, and the yolk spreads immediately, you need to smell it, if there is no strange smell, you can eat it.<\/p>\n
7 Yolk shape<\/h4>\n
You need to break the egg and put it on a plate. If the yolk retains its shape, then it is fresh, if it spreads, then it is not the first freshness (unless, of course, the yolk was touched when breaking). In this case, the scent will help: if there is no smell, the egg can be fried, if an unpleasant smell appears, without regretting to throw it away.<\/p>\n
Once cooked<\/h3>\n
What if after cooking the egg you find that the production date is too old? Do not rush to throw out the boiled eggs.<\/p>\n
Heat treatment will not kill the pungent odor. Therefore, if you, after cleaning the egg, felt that it was “smelly”, feel free to send it to the trash can. Pay attention to how the shells are peeling off during the cleaning process. A fresh egg will make you suffer, the old one will come off without any problems.<\/p>\n
Checking in the store<\/h3>\n
When choosing a product in a store, the buyer cannot determine whether an egg is rotten by placing it in water. In this situation, other methods will help to check for freshness.<\/p>\n
The first thing to look out for is the expiration date. Manufacturers mark products by affixing the category and date of production.<\/p>\n
Spoiled foods can also occur within the expiration dates. Such situations are possible if the conditions of transportation or storage in the store are violated.<\/p>\n
The most effective way, in this case, is to shake the testicle. By making quick up and down movements at ear level, the consumer should not hear any sounds. Such a product can be bought without fear for the health and quality of food. A bubbling noise, on the other hand, indicates more air inside the egg.<\/p>\n
\nA food product with a lower weight characteristic for a particular category will not pass the quality test. For this method, you will need electronic scales, which are not available in every store.<\/p>\n<\/blockquote>\n
Ovoscope transillumination<\/h4>\n
This method, in fact, is similar to the previous one, but technologically more advanced and, as a result, informative. With the help of the PKYA-10 device, several pieces can be illuminated at once – they are placed in the compartments of the cylinder, at the base of which an incandescent lamp is installed. The device operates on a 220 W network. How to do this is described step by step in the instructions for the equipment.<\/p>\n
The quality of a broken egg can also be recognized. The state of the protein and yolk directly depends on their age. The fresh shell does not flow and the core is round and resilient. The liquid state and loose core indicate the rottenness of the product.<\/p>\n
Can I check the freshness of eggs in the store?<\/h2>\n
There is such a device, called an ovoscope, and is designed to check the freshness of eggs. It can be seen in some large stores and supermarket chains.<\/p>\n
The shell of eggs perfectly transmits light, which is the basis of the action of the device. To check, the egg should be placed in a special compartment, and then, pass light through it.<\/p>\n
The fresher the test egg, the less darkening in the center of the egg will be. If an egg shines through with an even light around the perimeter, but there is a dark spot in the center, this indicates that the egg is good and edible, but it does not have the first freshness.<\/p>\n
If the dark spot is significant in size or begins immediately at the shell, such an egg does not need to be taken. Also, signs of egg spoilage can be called the presence of a spot that does not have an oval shape, the presence of several spots, or complete darkening without gaps.<\/p>\n

You can check with an ovoscope, as well as with water, any eggs, including chicken, quail, goose, duck and others.<\/p>\n
Can I eat eggs after the expiration date?<\/h2>\n

<\/a><\/p>\nWith meats, cottage cheese, and herbs, it's pretty easy to tell if they've gone bad. Since the egg is hidden in the shell, you cannot visually and smell them. Therefore, many throw away eggs according to the expiration date.<\/p>\n
Although eggs become inferior in quality after a certain date, they can still be eaten for a few more weeks, especially if stored properly. Refrigeration preserves the quality of the eggs and prevents the growth of bacteria. Eggs are unambiguously bad if you smell bad, but there are a few signs that can be seen a couple of days before.<\/p>\n
Why eating spoiled eggs is dangerous<\/h3>\n
Most chicken eggs contain salmonella and other pathogenic bacteria. They can be found both outside and inside the shell. It is very simple to protect yourself, it is enough to follow simple rules:<\/p>\n
\n- Refrain from buying dirty eggs – this is a sign of poor quality control in production;<\/li>\n
- Store eggs in the refrigerator between 0 and +5 degrees Celsius;<\/li>\n
- Wash eggs and hands thoroughly before cooking;<\/li>\n
- Subject eggs to severe heat treatment – fry or hard boil;<\/li>\n
- Do not eat rotten eggs, watch the expiration date.<\/li>\n<\/ol>\n
By the way, eggs, like milk, are pasteurized. These eggs are heated to a temperature high enough to kill bacteria, but low enough to keep the egg raw.<\/p>\n
Health hazard<\/h3>\n
A freshly laid egg inside the shell is sterile. Dangerous microorganisms can get on it from the chicken that carried it. Do not keep unprocessed eggs close to ready meals or raw foods, as there is a risk of contamination with harmful microorganisms.<\/p>\n
If food has been stored for a long time in violation of the conditions, then its deterioration (or rotting) is inevitable. Eating stale eggs is dangerous due to the multiplying salmonella bacteria. This microorganism causes severe poisoning, which can be fatal. Its incubation period is only 3 days.<\/p>\n
\nSalmonella enters the testicle through the pores of the shell, and dies only under the influence of heat treatment.<\/p>\n<\/blockquote>\n
Eating raw eggs is the most dangerous because it is not known how they were stored and transported, and in what conditions the chickens were kept by the farmer.<\/p>\n
Signs that shouldn't be suspicious<\/h2>\n
There are some features that, unknowingly, can be mistaken for evidence of corruption:<\/p>\n
\n- The greenish color of the yolk of a hard-boiled egg. This suggests that it was cooked longer than necessary. Or the water used for cooking is oversaturated with iron.<\/li>\n
- Blood clots inside the egg. They can sometimes resemble small pieces of meat. Quite acceptable formations. They are not dangerous, they are the result of egg formation processes.<\/li>\n<\/ul>\n
Everyone wants to eat fresh and quality food. The described methods will help you protect yourself and your loved ones from possible problems associated with eating stale and spoiled eggs. Bon appetit and be healthy.<\/p>\n
How long do eggs stay fresh?<\/h2>\n
According to the USDA, chilled eggs remain fresh for 3-5 weeks from the date they are packed on the carton. However, the packing date display does not indicate when the egg was hatched by the hen.<\/p>\n
Should I keep eggs in the refrigerator?<\/h2>\n
The USDA recommends chilling eggs as soon as possible to maintain freshness and reduce the risk of Salmonella contamination.<\/p>\n
The USDA also warns that you should not leave chilled eggs at room temperature for more than 2 hours. Cold eggs can fog up when heated, which can increase the risk of bacterial growth.<\/p>\n
Storage rules<\/h3>\n
How do you store eggs so that they remain usable for as long as possible?<\/p>\n
Here are some tips:<\/p>\n
\n- Be sure to keep your eggs in the refrigerator.<\/li>\n
- Store in a cardboard box.<\/li>\n
- Do not wash eggs that will be stored. You need to wash them just before cooking.<\/li>\n<\/ul>\n
Thus, eggs can be eaten after the expiration date, provided that they are stored correctly, do not have an unpleasant odor and discoloration of the egg white and yolk.<\/p>\n
In no case should you eat suspicious eggs, they can lead to food poisoning.<\/p>\n
How to prevent salmonellosis?<\/h2>\n
Egg poisoning is a consequence of non-compliance with the rules for the storage and hygiene of food products.<\/p>\n
The main factors contributing to infection:<\/p>\n
\n- Contamination.
\nDung imprints on the product indicate a violation of the hygienic requirements for keeping birds in a factory or backyard. Before eating such an egg, you must thoroughly wash it, rinse it with hot water or wipe it with a brush dipped in soapy water.<\/li>\n - Broken shell integrity.
\nIt is impossible to buy such a product, since pathogenic bacteria and infectious agents penetrate into the testicle with cracks.<\/li>\n - Shelf life.
\nExpired eggs are forbidden to be eaten, because even after heat treatment, pathogenic microorganisms remain inside. The product must be consumed before the expiration of the specified period.<\/li>\n - Time for preparing.
\nThe eggs should be boiled in boiling water for at least 5 minutes. High temperature exposure destroys bacteria and changes the consistency of the food.<\/li>\n<\/ol>\nThese indicators can be called precautions that every consumer must adhere to. If, despite attempts to determine the quality of the goods, a citizen is faced with the sale of an illiquid product, then he has the right to apply to the body exercising control in this area (Roskachestvo) for a veterinary and sanitary examination.<\/p>\n
