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.
