Why American Eggs Should Be Refrigerated
The rationale American eggs require refrigeration isn’t arbitrary. It comes instantly from a meals security regulation adopted within the Nineteen Seventies and the particular means that regulation removes the egg’s pure safety.
Each egg is laid with a pure protecting coating referred to as the bloom or cuticle. This skinny, moist membrane seals the pores of the eggshell, considerably slowing bacterial entry and moisture loss. The bloom is what permits an unwashed egg to sit down at room temperature safely for a time frame.
USDA rules require all commercially produced eggs in the USA to be washed and sanitized earlier than sale. The washing course of removes floor contaminants together with Salmonella micro organism, however it additionally strips away the bloom fully. With no bloom to guard the porous shell, micro organism can enter extra simply, and the eggs develop into considerably extra weak to spoilage at heat temperatures. Refrigeration compensates for the lacking bloom by slowing bacterial development.
This can be a direct commerce: the US removes floor micro organism by washing and compensates by requiring refrigeration. All the chilly chain from farm to processing plant to retailer to your kitchen exists as a result of that commerce was made.
Why European Eggs Do Not Want Refrigeration
A Totally different Strategy to the Similar Drawback
Most European nations take the other strategy to egg security. Egg washing is definitely prohibited in a lot of the EU earlier than eggs attain shoppers, as a result of washing opens the shell’s pores and removes the protecting cuticle. As a substitute, European producers concentrate on stopping Salmonella earlier than it reaches eggs within the first place, primarily by vaccinating laying hens towards the micro organism.
With the bloom intact and hens vaccinated, eggs in Europe might be saved safely at room temperature for a number of weeks. That’s the reason you see eggs on unrefrigerated cabinets in French supermarkets and Italian grocery shops. The strategy is completely different, not inferior. Analysis by USDA meals technologist Deana Jones, revealed within the journal Poultry Science, discovered that refrigerated eggs (no matter whether or not they have been washed) maintained Grade A high quality for 15 weeks on common. Unwashed eggs saved at room temperature degraded from Grade AA to Grade B in only one week.
The important thing level for American shoppers: the European strategy solely works as a result of the bloom is unbroken. Don’t apply European room-temperature storage guidelines to American store-bought eggs. They’ve been washed. Their bloom is gone. They want the fridge.
What About Farmers Market and Yard Hen Eggs?

The As soon as-Refrigerated-At all times-Refrigerated Rule
That is the rule most individuals get unsuitable. As soon as a refrigerated egg strikes to room temperature, condensation can kind on the surface of the shell as heat humid air contacts the chilly floor. That condensation, together with the temperature change itself, can drive micro organism by the porous shell. Transferring eggs repeatedly out and in of the fridge accelerates this course of and will increase meals security danger.
The USDA’s sensible steerage: if a refrigerated egg has been left at room temperature for greater than 2 hours, return it to the fridge and use it quickly. Don’t cycle eggs out and in of the fridge repeatedly over a number of days. Maintain them chilly and hold them there.
