In the UK , the British Egg Industry Council awards the lions stamp to eggs that, among other things, come from hens that have been vaccinated against Salmonella. Although the age of the egg and the conditions of its storage have a greater influence, the bird's diet affects the flavor of the egg. For those who do not consume eggs, alternatives used in baking include other rising agents or binding materials, such as ground flax seeds or potato starch flour. The most widespread standard in use is determined by United Egg Producers through their voluntary program of certification. The 20th century brought new technologies to milk production resulting in safer dairy products worldwide. This has not been the case in other countries, however, where Salmonella enteritidis and Salmonella typhimurium infections due to egg consumption are major concerns.

Chicken eggs are graded by size for the purpose of sales. Some maxi eggs may have double-yolks and some farms separate out double-yolk eggs for special sale. In North America, legislation requires eggs to be washed and refrigerated before being sold to consumers. This is to remove natural farm contaminants present in the cleanest farms and to prevent the growth of bacteria. In Europe legislation requires the opposite. Washing removes the natural protective cuticle on the egg and refrigeration causes condensation which may promote bacteria growth.
Although eggshell color is a largely cosmetic issue, with no effect on egg quality or taste, it is a major issue in production due to regional and national preferences for specific colors, and the results of such preferences on demand.
For example, in most regions of the United States , chicken eggs generally are white. In some parts of the northeast of that country, particularly New England , where a television jingle for years proclaimed "brown eggs are local eggs, and local eggs are fresh! Local chicken breeds, including the Rhode Island Red , lay brown eggs.
In Brazil and Poland , white chicken eggs are generally regarded as industrial, and brown or reddish ones are preferred. Small farms and smallholdings , particularly in economically advanced nations, may sell eggs of widely varying colors and sizes, with combinations of white, brown, speckled red , green, and blue as laid by certain breeds, including araucanas,  heritage skyline, and cream leg bar eggs in the same box or carton, while the supermarkets at the same time sell mostly eggs from the larger producers, of the color preferred in that nation or region.
These cultural trends have been observed for many years. By direct contrast, in Egypt it is very hard to source brown eggs, as demand is almost entirely for white ones, with the country's largest supplier describing white eggs as "table eggs" and packaging brown eggs for export. Research conducted by a French institute in the s demonstrated blue chicken eggs from the Chilean araucana fowl may be stronger and more resilient to breakage.
Research at Nihon University , Japan in revealed a number of different issues were important to Japanese housewives when deciding which eggs to buy and that color was a distinct factor, with most Japanese housewives preferring the white color. Egg producers carefully consider cultural issues, as well as commercial ones, when selecting the breed or breeds of chickens used for production, as egg color varies between breeds.
Commercial factory farming operations often involve raising the hens in small, crowded cages, preventing the chickens from engaging in natural behaviors, such as wing-flapping, dust-bathing, scratching, pecking, perching, and nest-building. Such restrictions may lead to pacing and escape behavior. Many hens confined to battery cages, and some raised in cage-free conditions, are debeaked to prevent them from harming each other and engaging in cannibalism.
According to critics of the practice, this can cause hens severe pain to the point where some may refuse to eat and starve to death. Some hens may be forced to molt to increase egg quality and production level after the molting. Laying hens often are slaughtered when reaching to weeks of age, when their egg productivity starts to decline. As male birds of the laying strain do not lay eggs and are not suitable for meat production, so they generally are killed soon after they hatch.
Free-range eggs are considered by some advocates to be an acceptable substitute to factory-farmed eggs.
Free-range laying hens are given outdoor access instead of being contained in crowded cages. Questions regarding the living conditions of free-range hens have been raised in the United States of America, as there is no legal definition or regulations for eggs labeled as free-range in that country. In the United States, increased public concern for animal welfare has pushed various egg producers to promote eggs under a variety of standards.
The most widespread standard in use is determined by United Egg Producers through their voluntary program of certification. Of these standards, "Certified Humane", which carries requirements for stocking density and cage-free keeping and so on, and "Certified Organic", which requires hens to have outdoor access and to be fed only organic vegetarian feed and so on, are the most stringent.
Egg producers in many member states have objected to the new quality standards while in some countries, even furnished cages and family cages are subject to be banned as well. The production standard of the eggs is visible on a mandatory egg marking categorization where the EU egg code begins with 3 for caged chicken to 1 for free-range eggs and 0 for organic egg production.
In battery cage and free-range egg production, unwanted male chicks are killed at birth during the process of securing a further generation of egg-laying hens.
A popular Easter tradition in some parts of the world is a decoration of hard-boiled eggs usually by dying, but often by spray-painting. A similar tradition of egg painting exists in areas of the world influenced by the culture of Persia. Before the spring equinox in the Persian New Year tradition called Norouz , each family member decorates a hard-boiled egg and they set them together in a bowl. They may be rolled in some traditions. In Eastern and Central Europe, and parts of England, Easter eggs may be tapped against each other to see whose egg breaks first.
Since the sixteenth century, the tradition of a dancing egg is held during the feast of Corpus Christi in Barcelona and other Catalan cities. It consists of an hollow eggshell, positioned over the water jet from a fountain, which causes the eggshell to revolve without falling. From Wikipedia, the free encyclopedia.

Humans use many different methods for gathering food which include farming, hunting, gardening, foraging and fishing. Humans eat meat from a number of different animals, common examples include meat from chickens, cows, sheep and pigs.
Other food products that come from animals include milk, eggs and honey. Although humans are omnivores eating both plants and animals , many people choose not to eat meat and fish, they are known as vegetarians. Food for human consumption is typically made from plants and animals but we also eat other products such as fermented foods and fungus mushrooms, truffles etc.
