One of many objectives of this weblog for the previous 15 years is to encourage folks to take their meals sourcing domestically.

In different phrases, redirect as a lot of the meals price range as potential to native producers or artisans.

What this implies, in follow, is the elimination of the “meals intermediary” that’s the Industrialized Meals System.

The Industrialized Meals System is the place practically the entire unhealthy issues occur to your meals.

This consists of nourishing, entire meals like natural eggs. Even pastured and free-range varieties from small farms can fall sufferer to its regulatory risks.

You see, once you take a high quality product from a small farm and cross it by means of the Industrialized Meals System, poisonous practices and meals adulteration normally happen.

It’s not the identical product when it emerges from the Industrialized Meals System as when it first entered!

Let’s check out how natural eggs are washed as a straightforward instance.

USDA Natural Egg Wash Requirements

Whereas many individuals keep away from typical eggs as they know in regards to the poisonous chlorine washes which might be normal follow, because it seems, egg (and carcass) washes for USDA natural manufacturers really aren’t significantly better!

Egg shells are extremely porous and any chemical used to scrub the shell and coat it afterward can find yourself within the egg itself.

In keeping with Part 205.605 of USDA Poultry Pointers, the next chemical compounds are accredited to be used as natural egg washes. (1)

  • Sodium hypochlorite
  • Potassium hydroxide, sodium hydroxide
  • Hydrogen peroxide (H2O2)
  • Sodium carbonate (washing soda)
  • Peracetic acid (Peroxyacetic acid)

Whereas two of those chemical compounds (H2O2 and sodium carbonate) are secure, the others are most positively not!

For instance, sodium hypochlorite is corrosive and an environmental hazard. (2)

Potassium hydroxide is corrosive and an irritant. (3)

Peracetic acid is flammable and corrosive in addition to an irritant and environmental hazard. (4)

How these chemical compounds are in some way allowed in “natural” egg manufacturing is past me.

Why doesn’t the USDA solely enable secure substances corresponding to hydrogen peroxide and sodium carbonate? Why the opposite poisonous trio as properly?

Poisonous Vegetable Oil Coating after Washing

One other widespread follow is for natural eggs to be coated with vegetable oil after washing.

This “seals” the porous egg shells “for security”.

Part 205.605 of USDA Poultry Pointers permits for this poisonous follow as properly. (1)

What oils are used? Your guess is pretty much as good as mine, but it surely doesn’t should be listed as a result of it’s an “trade normal”. 🙄

My guess is that the most cost effective seed oils are used corresponding to refined canola or sunflower oil.

Learn how to Discover Protected, Unwashed Eggs

The unhappy fact is that it’s crucial for customers to teach themselves and take evasive motion with regards to sourcing eggs. They can not depend on the USDA or natural requirements to guard them.

For my part, the very best resolution is to maintain yard chickens your self. Our household has stored a small flock for over 10 years now, and I extremely suggest it!

The following neatest thing is to acquire contemporary, unwashed eggs from a neighbor or farmer’s market. Keep away from natural eggs from the shop as a lot as potential.

In case you suppose unwashed eggs are harmful, they aren’t!

The “bloom” or pure coating on an egg is extremely protecting, even permitting for the eggs to stay unrefrigerated for a lot of days.

In Europe and different elements of the world, unwashed (and unrefrigerated) eggs might be discovered at shops and even out on the street!

The image under is a photograph I took myself of unwashed eggs sitting out unrefrigerated in a healthfood retailer within the Netherlands in 2018.

The following image under is a photograph I took on the streets of Venice, Italy in 2015.

Fully unrefrigerated, unwashed contemporary eggs out within the open air subsequent to greens and fruit!

The scare ways of the USDA towards unwashed eggs are utterly unwarranted!

Finest Natural Egg Manufacturers

If you end up in a meals desert the place contemporary, unwashed eggs usually are not out there and retaining a couple of hens your self will not be an possibility, then you’ll need to do some investigation of the out there egg manufacturers in your space.

The perfect natural egg model rating system I’ve seen is from the Cornucopia Institute. (5, 6)

Whereas this in-depth egg scorecard investigates an exhaustive record of standards about dozens of natural egg manufacturers, sadly, the egg-washing course of will not be amongst them!

Thus, I might counsel utilizing this scorecard to winnow down the record of egg manufacturers which might be greatest and out there in your space.

Then, contact every farm instantly (by cellphone is greatest in my expertise), to acquire data on the chemical compounds used to scrub the eggs and the vegetable oil used to coat them earlier than they’re positioned in cartons and shipped to your retailer shelf.

In a worst-case situation, should you shouldn’t have a “greatest” natural model out there in your space that makes use of unhazardous hydrogen peroxide or sodium carbonate as an egg wash, then no less than make sure you re-wash the eggs your self completely in heat, soapy water earlier than utilizing.

Whereas this isn’t a failsafe methodology given the porous nature of egg shells, it could no less than cut back the possibility that chemical or rancid vegetable oil residues get into the eggs once you crack them.
