"Whole Egg Waste" - Unfit for Humans, But Fine for Dogs and Cats

By Dr. Becker

Last year, an economic development program  in Canada  awarded a large grant to help a former egg processing plant re-open as a  business that converts egg waste into pet food ingredients.

The plant, which had been closed for four  years, now processes whole egg waste from egg grading plants to produce  powdered pet food ingredients.

It also extracts egg whites from discarded egg  shells and produces liquid egg white that is used as a binding agent in pet  food.

According to the company, the powdered egg  product has up to 50 percent protein, and the egg white binding agent is 80  percent protein.

Government officials feel the grant is helping to turn "… something that  was considered waste unto a usable product."

They also hope the re-opening of  the plant will benefit the community and create jobs.

I'm all for finding ways to make use of  food waste products, for example, as an energy source or as fertilizer.

But I'm  certainly not in favor of repurposing waste as nutrition for dogs and cats.

In the U.K., egg and egg products not fit  or intended for human consumption are considered animal by-products.

They fall  into the same category as manure and digestive tract content, hides and skins,  wool, feathers, semen, ova and embryos, shellfish shells and "other products of  animal origin."i

"Whole Egg Waste"

According to a U.S. pet food ingredient  manufacturer who sells dried egg productii , there  are three main sources of the whole egg waste used in pet food: 'Grader,'  'Breaker,' and 'Hatchery.'

Grader egg waste comes from egg processing  facilities that sell to supermarkets. These eggs need to look appealing when  grocery shoppers open the carton. Any egg with a cracked or dirty shell is  tossed into an 'inedible' bin.

Breaker egg waste comes from facilities  that use eggs in prepared or frozen mixes used by restaurants, bakers and other  food service outlets. The waste that comes from breaker eggs is mostly egg  white left after the yolk is separated.

These two types of whole egg waste are,  according to the pet food ingredient company, collected daily, kept  refrigerated, and dried within a day of collection.

Hatchery waste is liquid from eggs that  didn't hatch. It tends to lead to foul odors in the dried egg product, so it presumably  isn't used as often as the other two types of whole egg waste.

All three categories of eggs have been  deemed unfit for human consumption...
