What is the main difference between regular fresh eggs and Pasteurized fresh eggs?

Regular fresh eggs are packed for sale after they are collected from hens that lay them. PASTEURIZED fresh eggs have undergone a pasteurization process to kill Salmonella Enteritidis (SE) bacteria and Bird Flu virus that may be present on or inside the eggs.

What is Salmonella?

Salmonella, the name of a group of bacteria, is a common cause of food poisoning. According to the Department of Health in Vermont, USA, "Salmonella is commonly found in raw food products that come from animals, such as eggs, egg products, meat, meat products, unpasteurized milk, or other unpasteurized dairy products. Thorough cooking and processing effectively kills salmonella bacteria."
(http://healthvermont.gov/prevent/salmonella/Salmonella.aspx)

Most people infected with Salmonella develop diarrhoea, fever, abdominal cramps, and vomiting 12 to 72 hours after infection. Symptoms usually last 4 to 7 days and most people get better without treatment. However, in some people, the diarrhea may be so severe that they need to be hospitalized. In these patients, the Salmonella infection may spread from the intestines to the blood stream, and then to other body sites and can cause death unless the person is treated quickly with antibiotics. Certain people are at greater risk for severe illness and include pregnant women, young children, older adults and people with weakened immune systems.

Egg Story eggs are stringently pasteurized with a multi-patented USA technology to kill Salmonella bacteria and Bird Flu Virus if present inside and outside the eggs. Therefore, every member of your family, young or old can indulge in the wholesome goodness of Egg Story eggs cooked any way they like.

Why are eggs pasteurized?

Eggs are laid in an environment where hens' excretion and airborne bacteria may be present, hence bacteria can be present on egg shells. Bacteria from the environment can enter the pores on the egg shell if the natural protective layer if breached. Bacteria can also be found INSIDE an egg as bacteria can be passed on to the egg during egg formation if the hen laying the egg is infected by Salmonella Enteritidis (SE) bacteria. A common bacteria found in eggs is SE.

Egg Story eggs are stringently pasteurized with a multi-patented USA technology to kill Salmonella bacteria and Bird Flu Virus if present inside and outside the eggs. Therefore, every member of your family, young or old can indulge in the wholesome goodness of Egg Story eggs cooked any way they like.

Is it true that if the shell of a fresh egg is un-cracked eggs, it will not contain Salmonella bacteria inside?

No. Even the most perfect-looking fresh egg whose shell is smooth and un-cracked can contain Salmonella bacteria inside as bacteria can be passed on to the egg during egg formation if the hen laying the egg is infected by Salmonella Enteritidis (SE) bacteria. Chickens can harbor Salmonella without being sick themselves.
However, choosing eggs with no cracks is always a good idea. Once eggs are cracked, new bacteria from the environment can enter them.

Can I pick out eggs that contain Salmonella bacteria through taste and/or smell?

No. Salmonella bacteria is imperceptible in an egg. You can't see, smell, or taste them. Salmonella bacteria that causes foodborne illness is different from spoilage bacteria, which causes food to taste and/or smell bad. Thus, if an egg contains harmful Salmonella bacteria, it does not necessarily taste or smell bad. Pasteurization kills such harmful and imperceptible Salmonella Enteritidis (SE) bacteria.

Why is there a wax coating on Egg Story Pasteurized Fresh Eggs?

We apply a thin layer of food-grade wax to seal in the freshness of Egg Story Pasteurized Fresh Eggs and to further keep out any harmful bacteria the eggs could encounter once they leave our facility. This wax coating is barely noticeable and completely safe.

Can I pasteurize fresh eggs effectively at home?

Precise temperature and time controls are the key to effective pasteurize eggs to accurately kill SE bacteria and Bird Flu virus if they are present inside and outside the eggs. These cannot be easily achieved using cooking equipment at home. Egg Story eggs are pasteurized using a patented process based on extensive scientific development and precision controls.

The US Department of Agriculture explains it this way: "The equipment to pasteurize eggs isn't available for home use, and it is not possible to pasteurize shell eggs at home without cooking the contents of the egg."

How does pasteurization affect the colour of the egg yolk?

Pasteurization does not affect the colour of the egg yolk. The colour of the egg yolk is dependent upon the feed of the hen.

Do pasteurized eggs taste different from regular eggs?

Views vary in regards to whether pasteurized eggs taste different from regular eggs as individual taste preferences differ. We take the view published in http://shelflifeadvice.com/content/it-time-switch-pasteurized-eggs : "... if you don't have the tastebuds of a connoisseur, you'll find little or no difference between pasteurized and unpasteurized eggs."

If I wash eggs before use, will that remove all the bacteria that may be present?

Salmonella Enteritidis (SE) bacteria, if present, can be found outside and inside the egg. Bacteria can be found INSIDE an egg as bacteria can be passed on to the egg during egg formation. Therefore, washing egg shells does not remove bacteria that may be present inside the eggs.

Is egg pasteurization a form of radiation?

No. Egg Pasteurization uses natural heat from water and not radiation, to kill Salmonella Enteritidis (SE) bacteria and Bird Flu virus that may be present on or inside the eggs.

Are chemicals and preservatives used in the pasteurization process?

No chemicals and preservatives are used in the pasteurization process.

What is the difference between Pasteurized and Sanitized Shell Eggs?

Sanitized eggs are washed with a sanitizing chemical to kill bacteria or virus that may be present on the surface of egg shells. Pasteurized shell eggs undergo a warm water bath where precise time and temperature standards accurately pasteurizes the eggs to kill Salmonella Enteritidis (SE) bacteria and Bird Flu virus that may be present BOTH on the surface and inside the eggs.

What is the difference between Pasteurized and UV Sanitised Shell Eggs?

UV Sanitised eggs are sanitised with ultraviolet light to reduce the bacteria or virus that may be present on the surface of egg shells.
Pasteurized shell eggs undergo a warm water bath where precise time and temperature standards accurately pasteurizes the eggs to kill Salmonella Enteritidis (SE) bacteria and Bird Flu virus that may be present outside and inside the eggs.

Are Organic Eggs the same as Pasteurized Shell Eggs?

No, "organic" does not mean "pasteurized". Organic eggs are eggs from chickens that are fed an organic diet without antibiotics, synthetic hormones or pesticides. Pasteurized eggs have undergone a pasteurization process to kill Salmonella Enteritidis (SE)  bacteria and Bird Flu virus that may be present on or inside the eggs.

Are Organic Eggs higher in nutritional value than Pasteurized Shell Eggs?

Not necessarily. The nutritional value of an egg depends on the diet fed to the hen, not on how the hens are raised or whether the egg has undergone a pasteurization process.
Read http://www.time.com/time/health/article/0,8599,2002334,00.html for more information. 

Is there a nutritional difference between brown eggs and white eggs?

Not necessarily. The nutritional value of an egg depends on the diet fed to the hen, not on the colour of the egg shell. The breed of hen laying the egg determines the variance in shell color. White hens produce white eggs, and brown/red hens produce brown eggs. 

How should I store my pasteurized shell eggs after purchase?

Please store Egg Story Pasteurized Fresh Eggs in the chiller for maximum freshness.

Is the expiry period for pasteurized eggs the same as that of regular eggs?

Egg Story Pasteurized Fresh Eggs have a prolonged expiry period of 60 days from date of production compared to 30 days for regular eggs. Please store Egg Story eggs in the chiller to ensure maximum freshness.

What are the benefits of Omega 3&6?

Egg Story Pasteurized Fresh Eggs contain Omega 3&6.

Omega-3 and Omega-6 fatty acids are the 2 essential fatty acids, termed essential fatty acids (EFA) that the human body cannot produce on its own. They must be ingested. They are important for brain development, immune system function and blood pressure regulation.

What are the benefits of Vitamin E?

Egg Story Pasteurized Fresh Eggs contain Vitamin E. 

Vitamin E is a fat soluble antioxidant, which can be obtained only as a food supplement. The most widely known health benefits of vitamin E are protection against toxins such as air pollution, premenstrual syndrome, eye disorders such as cataracts, neurological diseases such as Alzheimer's disease, and diabetes. 

The health benefits of vitamin E come from its antioxidant properties. Antioxidants remove free radicals — the unstable compounds that damage the cell structure. Immunity levels improve when vitamin E is consumed. Another important benefit of vitamin E is that it reduces cholesterol and the risk of developing cancer. Another widely known health benefit of vitamin E is in skin care and hair care.

What are the stringy white pieces in egg whites that are occasionally present in eggs?

These rope-like strands of egg white, called chalazae (ka-LAY-zee) are not imperfections or beginning embryos but a natural, edible part of the egg. They keep the egg yolk centered in the thick white. Chalazae are another sign of freshness because as the egg ages, the chalazae becomes less noticeable.

Can Egg Story Pasteurized Fresh Eggs be used to prepare hard-boiled eggs?

Egg Story Pasteurized Fresh Eggs are exceptionally fresh as they are produced from freshly laid eggs. The protective food-grade coating applied over Egg Story eggs after pasteurization seals up the numerous pores present on the egg shell to preserve the eggs' freshness and prevents contaminants from entering the eggs. Egg Story eggs are stored in chillers after pasteurization to further ensure maximum freshness.

Because Egg Story Pasteurized Fresh Eggs are very fresh, their shells are more difficult to peel off when preparing hard boiled eggs, especially when they are freshly produced.

Here is a scientific explanation on why peeling fresh egg shells are difficult :
With eggs that are just a day or two old, the membrane beneath the shell sticks tightly to the shell making peeling the egg almost impossible. After a few days in the refrigerator the egg becomes easier to peel. Why is this? In fresh eggs the albumen sticks to the inner shell membrane more strongly than it sticks to itself because of the more acidic environment of the egg. The white of a freshly laid egg has a pH between 7.6 and 7.9 and an opalescent (cloudy) appearance due to the presence of carbon dioxide. After the protective coat is washed off the egg shell the egg becomes porous and begins to absorb air and loose some carbon dioxide contained in the albumen. This reduces the acidity of the egg which causes(after several days in the refrigerator) the pH to increase to around 9.2. At higher pH the inner membrane does not stick as much to the albumen so the shell peels off easier. In addition, as the egg gets older it will shrink and the air space between the egg shell and the membrane will get larger.
