Why do only Americans refrigerate eggs?

Americans refrigerate eggs because the U.S. washes them, which removes the natural protective cuticle, making them vulnerable to bacteria like Salmonella, so refrigeration slows bacterial growth and preserves quality, a necessity unlike in Europe where unwashed eggs retain their cuticle and are sold at room temperature. This washing process is mandated by the USDA to control bacterial contamination but requires constant chilling from farm to table, as a cold, washed egg left out can "sweat," allowing bacteria to enter.

Why are eggs only refrigerated in the US?

That's because the way eggs are stored depends on where they're produced. Prompted by concerns about spoilage and foodborne illnesses, U.S. egg producers and processors began washing and refrigerating their eggs in the early 1970s.

Why do other countries not refrigerate their eggs?

Eggs in Germany (and much of Europe) are typically sold unrefrigerated because of deliberate differences in production, processing, and regulatory approach that prioritize preventing contamination before the shell is breached. Key reasons and mechanisms: Hygienic production and testing.

Why do Mexicans not refrigerate eggs?

Eggs aren't refrigerated in Mexico because they aren't washed, leaving a natural protective outer layer (cuticle) intact that keeps bacteria out, making them safe at room temperature, unlike in the U.S. where washing removes this layer, necessitating refrigeration to prevent spoilage. Mexican eggs are sold unwashed and often locally, relying on this cuticle and a shorter supply chain for freshness. 

Can American eggs be unrefrigerated?

American eggs must be refrigerated to prevent bacteria growth and ensure safety. Eggs can sit at room temperature for up to 2 hours before they become unsafe to use.

20 Food's You'll Never Buy Again After Knowing How They Are Made

Why shouldn't you keep eggs in the fridge?

An egg kept in the fridge is more likely to "go off" as the porous shell will allow water to be absorbed.

Why doesn't Japan refrigerate eggs?

In various parts of the world, particularly within European countries and Japan, eggs are often left unrefrigerated due to their unwashed state, which preserves the natural protective coating or cuticle. This coating acts as a barrier against bacteria, reducing the risk of salmonella contamination.

Why is milk not refrigerated in Mexico?

Both methods of pasteurization ensure that milk is fresh and safe, but the UHT pasteurization method makes milk shelf-stable, which means that it does not require refrigeration for storage.

Why do Italians not put eggs in the fridge?

1️⃣ Italian eggs aren't washed before sale, which means they keep their natural protective coating. This coating keeps them fresh at room temperature for weeks! No fridge needed. 2️⃣ European food regulations actually prohibit egg washing and discourage refrigeration.

Why don't Europeans refrigerate milk?

But as a result, American milk has a shorter shelf life—around seven to 10 days—and must be refrigerated. Meanwhile, the rest of the world uses ultra-high-temperature or ultra-heat-treated pasteurization (UHT), which heats the milk to an even higher temperature than HTST.

Why do washed eggs have to be refrigerated?

Unwashed eggs have a protective layer called a cuticle and can be stored on the counter. This protective coating helps keep bacteria out. Washing eggs removes the cuticle. As a result, washed eggs must be refrigerated to prevent contamination.

Why are eggs in the US not shelf stable?

That's because the way eggs are stored depends on where they're produced. Prompted by concerns about spoilage and foodborne illnesses, U.S. egg producers and processors began washing and refrigerating their eggs in the early 1970s.

Why is milk in the US refrigerated?

“The result is there are only a few bacteria in the milk, even after pasteurization, that can eventually cause the milk to spoil over time. Refrigeration slows down the growth of these spoilage bacteria so you can enjoy your milk for longer.”

Does washing eggs reduce shelf life?

Leaving the bloom intact helps protect the egg naturally. If an egg is visibly soiled, you can spot-clean it just before use, not before storage. Washing too early increases the risk of contamination and shortens shelf life.

Why can I drink milk in Europe but not the US?

People often find they can tolerate dairy in Europe better than in the U.S. due to differences in farming (no rBGH hormone in EU), processing (more UHT milk), cow diet/health, and European dairy products' lower lactose (aged cheeses) and less inflammatory aspects, contrasting with high-inflammation U.S. diets, suggesting U.S. dairy might contain more potential irritants like antibiotics or hormones, making European dairy seem easier to digest. 

Should Americans drink water in Mexico?

In North America, the only countries that have generally safe tap water are Canada, Greenland, and the United States. Mexico is one popular tourist destination to cause concern. Drinking water in Mexico is a common cause of traveler's diarrhea. Stick to sealed bottled water instead.

Why are eggs in Mexico so cheap?

As any American who travels to Mexico can tell you, most grocery store goods are significantly less expensive than in the U.S. This includes eggs, even at a time of record high prices. The reasons for this are multifaceted, but a large factor is the lower cost of labor when compared to the U.S.

Why don't Europeans wash eggs?

In other parts of the world, such as Europe, authorities approach the threat of Salmonella quite differently. Eggs there are not required to go through extensive washing, which leaves the protective coating on the egg.

Why can't American eggs be eaten raw?

Unbroken, clean, fresh shell eggs may contain Salmonella Enteritidis (SE) bacteria that can cause foodborne illness. To be safe, eggs must be safely handled, promptly refrigerated and thoroughly cooked.

Are eggs ok if left out overnight?

Refrigerated eggs should not be left out more than 2 hours.

What are signs of salmonella in eggs?

Most people infected with Salmonella develop diarrhea, 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.

Why do supermarkets not put eggs in the fridge?

Eggs are not in fridges in supermarkets but ARE in coolzones near the fridges. This is to keep a low and constant temperature. If you use eggs quickly at home, shelf storage is ok however, if you don't, then put them in the fridge.
