Description

Bulk 50 lb Perma-Guard Fossil Shell Flour (Food Grade Feed Additive)

Perma-Guard Fossil Shell Flour is the benchmark for organic, freshwater Food Grade Diatomaceous Earth. Harvested from rare freshwater deposits of microscopic Aulacoseira algae, this 50 lb bulk bag delivers pure, un-calcined amorphous silica engineered to keep animal feed dry, free-flowing, and fresh for high-volume farm operations.

Under a microscope, these ancient freshwater diatoms feature strong, porous honeycomb-like cylinder shells. Unlike saltwater deposits, which fracture easily into fragile fragments, Perma-Guard diatoms maintain their structural integrity to deliver maximum moisture absorption, surface coverage, and mechanical effectiveness without dissolving in liquids.

Key Agricultural & Homestead Applications:

  • Feed Flowability & Anti-Caking: Prevents molasses, oils, and moisture from causing feed rations to clump or spoil in humid storage bins. Mixing up to 2% of the dry feed ration protects grains from molding, reducing overall waste.
  • Digestive Support & Vitality: By separating feed particles as an anti-caking agent, it allows an animal’s natural digestive enzymes to completely surround each particle for maximum nutrient assimilation.
  • Environmental Deodorizer: Spreading the powder across barn floors, nesting boxes, coops, litter areas, and pet bedding naturally absorbs moisture and neutralizes odors to keep farm environments fresh.
  • Naturally Sourced Trace Minerals: Provides 28 naturally occurring trace minerals to support coat quality, skin integrity, and routine wellness.

Human consumption of DE varies and can be anywhere from 1/4 teaspoon to multiple tablespoons, once daily. The manufacturers recommended feeding rate is 1 heaping tablespoon daily.

It is best to slowly acclimate, any signs of constipation from a given dose, back off of that dosing slightly.

For parasite removal it is important to consume enough to allow wall to wall intestinal “coverage” during normal digestion. This dose will vary per individual.

Internal feeding of food grade diatomaceous earth helps eliminate most internal worms, though possibly not all. It’s also excellent when fed daily to keep down odors, since food grade diatomaceous earth is a drying agent & is eliminated from the body, exactly the way it went in, it helps reduce manure odor.

If fecal counts are not zero for worms & ova after feeding DE for 30 days, increase the daily dose. Feeding too small a dose of DE will not give desired results. Increasing the dose, even if greater than the above recommendations, will not harm anyone.

Difference from Acid Solutes. Purity of the Diatomaceous Earth was confirmed by MALDI mass spectometry, indicating that the material is virtually free from any other form of contamination.

MALDI is a technique in which the matrix is used to assist ionization of molecules on the surface of the material, caused by a blast from a UV Laser. This analysis confirms purity and suggests that even the above listed trace elements are not readily ionized and volatilized from the surface.

Apply in well ventilated space & wear appropriate protective PPE during application.

Avoid getting diatomaceous earth in the eyes at all cost. In the event of an accident thoroughly flush the eyes until all debris is clear. DE is drying to the eyes, so do not put it out when you or your pets are down wind of it.

Diatomaceous earth has great absorption properties which can dry the skin. You may want to use gloves for extensive handling as well as temporarily remove pets during application time.

Beware heavy use on carpets, the fine particulate may clog general vacuum cleaners. Shop-vac style vacuums may be used for larger cleanups without issue.

Perma-Guard is widely recognized as the pioneer of pure, freshwater diatomaceous earth products, having supplied organic-certified amorphous silica for agricultural, livestock, and home pest control for over 50 years. Derived exclusively from pristine ancient freshwater lake bed deposits, Perma-Guard diatoms feature high structural purity, high absorbency, and extremely low crystalline silica content (under 0.5%), making them non-toxic and OMRI-listed for organic operations.
