This is a 40-pound bag of OMRI-listed food-grade diatomaceous earth, a naturally occurring mineral blend of about 65% diatomaceous earth and 35% montmorillonite clay. It is used mainly as an anti-caking and flow agent in animal feed, at no more than 2% of the total diet. The OMRI listing makes it suitable for certified organic operations, which is its main edge over generic feed-grade DE. It suits farmers, homesteaders and pet or livestock owners who buy in bulk; shoppers wanting small household amounts will find a 40-pound bag far more than they need.
