Food Grade Diatomaceous Earth (Fossil Shell Flour) has many uses: in the household, with pets, on plants, around livestock, and for stored grain. It is totally organic and listed with OMRI. With more than 600 deposits of diatomite west of the Mississippi—and only four (to our knowledge) that can be considered food grade—it is very important that people know what they are using. The vast majority of diatomite deposits are impure. When diatomite is formed, water currents bring in foreign material that mixes with the microscopic diatom shells. This type of diatomite is absolutely without value for practical purposes, but many people tend to think that if it is “Diatomaceous Earth,” then it has the same value as other, purer deposits. There are many places where diatomite deposits can be loaded up “for free,” but generally this substance has no value. If this impure diatomite is sold for practical usage, the customer may end up with an unpleasant surprise.
