Our take on the Diatomaceous Earth Food Grade Diatomaceous Earth

Harris Ground Fresh is a food-grade diatomaceous earth sold as a fine, ground powder in a 4 lb container. It is OMRI listed for organic use and GRAS recognized by the FDA, and the label allows mixing it into animal feed for cattle and poultry. Compared with feed-store diatomaceous earth brands, its main draw is the organic and feed-use certifications rather than any special formulation. It suits livestock and poultry keepers who want a plain, certified powder, not shoppers looking for a pesticide-grade product.

Questions and answers

Is this the same as pool-grade diatomaceous earth?
No. This is food grade and labeled for animal feed. Pool grade is heat-treated and contains crystalline silica, so it should not be fed or handled the same way.
Can I mix it into chicken feed?
The label lists cattle and poultry and says it can be used in animal feed. Follow the label's mixing directions rather than guessing a ratio.
What does OMRI listed mean?
OMRI is the Organic Materials Review Institute. Its listing means the product meets standards for use in organic production.
What does GRAS mean?
Generally Recognized As Safe, an FDA status. Harris states this product holds it as a food-grade item.
How should I store it?
Keep it dry and sealed. Diatomaceous earth absorbs moisture, and a clumped powder is harder to mix evenly into feed.
Is it safe around animals other than cattle and poultry?
The label covers cattle and poultry only. For other animals, check with a vet before feeding it.
