Egg Handling on the Farm

Eggs seem simple—but how they’re handled between the hen and your kitchen can make a big difference in how they should be stored and used safely.

You may have noticed that some farms sell unwashed eggs, others refrigerate, and advice online can feel contradictory. Add in comparisons to Europe, discussions about the egg “bloom,” and concerns about Salmonella, and it’s no wonder people feel confused.

Our goal here isn’t to tell anyone they’re doing it wrong—but to explain the why behind different egg-handling practices and to share how we handle eggs here at Drip Spring Hollow Farm.

When a hen lays an egg, it’s coated in a thin, natural protective layer called the cuticle, or “bloom.” This coating helps seal the shell’s tiny pores and can slow moisture loss and bacterial entry.

Because of this, eggs that are not washed and remain clean can sometimes be stored for a period of time without refrigeration. This is why many European countries sell eggs unwashed and unrefrigerated.

However, research from the USDA’s Agricultural Research Service shows that the cuticle does not remain intact indefinitely. 

Studies have found that:

• the cuticle dries, degrades, and can slough off over time, 
• its protective effect diminishes after the egg is laid, 
• and from an evolutionary standpoint, the cuticle’s primary role is regulating gas exchange during incubation—not preventing modern foodborne pathogens like Salmonella.
   

In controlled studies comparing different storage methods, USDA researchers found that refrigeration was the single most important factor in maintaining egg quality over time, regardless of whether eggs were washed or unwashed. Eggs stored at room temperature—washed or not—lost quality much more rapidly than refrigerated eggs.

In other words, the bloom is helpful, but it isn’t permanent or foolproof.

In the United States, most eggs are washed, sanitized, and refrigerated. Washing removes visible dirt and bacteria from the shell, but it also removes the bloom. Once that natural coating is gone, refrigeration becomes essential to slow bacterial growth and maintain quality.

This system developed alongside:

• large-scale production,
• long transportation distances,
• and extended storage times.
   

Both systems—washed/refrigerated and unwashed/unrefrigerated—can be safe, but they rely on very different handling rules and assumptions.

Pasture-raised eggs, like all eggs, can carry a risk of Salmonella. Some research has shown that smaller, non-conventional flocks may at times have higher Salmonella prevalence than large industrial systems—not because pasture-raised eggs are inherently unsafe, but because flock management, environment, and handling practices vary widely.

Recent recalls of pasture-raised eggs remind us that:

• no egg is risk-free,
• marketing terms don’t replace safe handling, 
• and refrigeration and proper cooking still matter.
   

This is why food safety is always a shared responsibility between the farmer and the person preparing the food.

Another key difference between European and U.S. egg systems has to do with how hens themselves are managed, not just how eggs are handled afterward.

In much of the European Union, laying hens are routinely vaccinated against Salmonella, particularly Salmonella Enteritidis. This reduces the risk of the bacteria being present inside the egg before the shell ever forms, which helps make unwashed, room-temperature storage safer within that system.

In the United States, Salmonella vaccination practices vary widely. Large commercial operations may vaccinate their flocks, but pasture-raised and small-scale farms are not universally required to do so, and some choose different management approaches. This means that eggs from pasture-raised flocks may come from vaccinated hens—or from hens that are not vaccinated at all.

Because vaccination status isn’t always visible or standardized in direct-to-consumer sales, handling and storage practices become especially important. Refrigeration, clean handling, and thorough cooking all help reduce risk, regardless of production style.

This difference helps explain why egg practices that work well in Europe don’t always translate directly to U.S. pasture-raised systems—and why transparency and consistency matter more than labels alone.

At Drip Spring Hollow Farm, our eggs are:

• Cleaned using water only — no detergents, soaps, or chemical cleaners 
• Refrigerated promptly after cleaning 
• Handled carefully to minimize contamination from the start
   

Because cleaning with water removes the bloom, refrigeration is an important part of our process. Even so, we still recommend that eggs be washed just before use.

One of the joys of pasture-raised eggs is their variety. Our eggs come in a wide range of natural colors and shades—something many store-bought eggs don’t offer.

At the same time, colorful eggs can be more tempting to handle, especially for children. 

Unwashed or minimally handled eggs left out on the counter can become a hidden risk if:

• multiple people touch them 
• hands aren’t washed afterward,
• or eggs come into contact with ready-to-eat foods.
   

This isn’t about blame—just awareness. Eggs are raw agricultural products, and good handwashing habits matter, particularly in homes with kids.

No matter where your eggs come from:

• Store eggs refrigerated at 40°F or colder 
• Wash hands after handling eggs or cartons 
• Cook eggs until yolks and whites are firm 
• Avoid raw or undercooked eggs in dressings or sauces 
• Stay informed about recalls when they occur
   

Eggs are handled differently around the world for different reasons. What matters most isn’t ideology, but cleanliness, consistency, refrigeration, and transparency.

We believe the best approach is one that respects:

• the biology of the egg,
• modern research and food safety, 
• and the families who bring our food into their kitchens.
   

If you ever have questions about how we handle our eggs—or how to use them safely at home—we’re always happy to talk.
