* Diatomaceous Earth (Fossil Shell Flour):

Is best known for it's unique ability to kill bugs in stored grain and still be consumable. Our brand is deemed a food-grade product by the FDA and is therefore safe to use in animal feed, long-term food reserves and daily use. DE can also be used to filter water. DE is available in 1, 2, 5, 10 and 50 pound bags. Check out our other products containing DE such as the fire ant killer, household insecticide and more.

For anyone that has, or plans to have, grain or pasta in their food storage reserves, DE is a MUST!!
Protect your stored grain, beans, pasta and other foods with Diatomaceous Earth. DE is a natural insecticide that kills bugs mechanically (primarily by dehydration) instead of chemically. Foods treated with DE are safe to eat and the DE need not be cleaned off prior to eating. 1 cup of DE is sufficient to treat a 50# bag of grain against insect infestation. We mix 1/3 to ½ cup in each 5 gallon bucket of grain and sprinkle a little more around the top before sealing. We have opened and used grain that has been stored for over 4 years in this manner with 100% effectiveness.

DE can also be fed directly to livestock in grain or hay. Your animals will display a significant anticipation at feeding time when you use DE to treat their food. We have many testimonial letters from companies, veterinarians and individuals that indicate that DE is effective in the elimination of internal parasites, stopping scours and reducing flies in animal pens. Also treat all crops to eliminate insect infestations.

Food Grade DE is available in 1, 2, 5, 10 and 50# bags. There are also several other DE products like Pet Powder, Fire Ant killer and Household Insecticide.

Just make sure you don't breathe any in as dust. It'll turn into cement inside your lungs, kinda like volcanic ash.

You can also take DE (food grade) yourself, it keeps your system clean (of worms and other parasites).

Use DE (Diatomaceous earth) (make sure it is food grade the same kind you use for your grains)to (for humans and animals) naturally control worms, fleas, flies and common pests found around animals.

It is a microscopic and organic way to control pests.

If food grade is used it perfectly safe for humans and animals to ingest (its added to Bisquick bread mixes) however if you find pool grade DE run the other way It can KILL YOU and your animals!!!

Here is a great place to learn about food grade DE, it gives you the dosage for humans and pets:

Daily recommended food grade diatomaceous earth feeding rates:

Kittens - 1/2 teaspoon
Cats - 1 teaspoon
Puppies - 1/2 to 1 tsp.
Dogs under 35 lbs. - 1 teaspoon
Dogs over 35 lbs. - 1 tablespoon
Dogs over 100 lbs. - 2 tablespoons
Cattle, Dairy Cows, & Hogs - 2% of dry feed ration
Chickens - 5% in feed
Goats & Sheep - 2% in grain
Horses - 1/2 to 1 cup in daily ration
*Humans - 1 heaping tablespoon daily

No professional packing house uses DE. If you pack your grains correctly, bugs won't be a problem.

The information regarding safety of inhalation and ingestion of DE is unclear at best, with much of it coming from places that SELL DE.

Some folks say "oh you can just wash it off your grains before using them"- no way to truly tell if you got them all, major waste of water, running wet wheat through a grinder will gum it up GREATLY. In short a waste of time IMO.

Do what you want to with your own food, but I try to look and see what the professionals are doing- NO professional packing house uses DE. You might find some Bubba Gumps place doing it, but the BIG packing houses do NOT use it.

Wikipedia warns of the INHALATION HAZARD of DE. Not something I want to put on my food.

The bottom line however is-

Your food = YOUR choice.

If you pack your grains within a reasonable amount of time of getting them- in other words don't let them sit around for six months before packing them- and pack correctly with mylar and oxygen absorbers the way the professional packing houses do, you WON'T NEED D.E.

DE is added to Bisquick and other prepackaged grains, it has been used for a loooooong time. DE is used to by holistic doctors to treat worms in humans. DE is used by large packing companies, they arn't on the label because it such a minute about.

How is it not on the label? Certainly something that poses an "inhalation hazard" would have to be put on the label of something like that. "Special interest" groups would tear them apart!

Also if that's the case then I'm SURE D.E. doesn't work- I've thrown out quite a bit of Bisquick that's been eaten up with bugs.

Hmm, odd. That in the packing FAQ's on major prep food distributors(walton, EE,honeyville etc) they make no mention of DE,Dry Ice, nitro flushes, etc. It has all gone Mylar and o2 absorbers.
While DE may have some use's there are better options to protect your food stores. But like anything else, it is a do what you feel safe with thing!:thumb:

In small quanities it is not dangerous, the minute amount that goes into the bisquick is very very small. Hubbers Granny use to work for a grain company (late 90's early 2000's) they added it to the grains going to other grain distributers to keep pests out. It breaks down there exo-skeleton and has no effect on our bodies. It has been used for years and is in alot of items you eat everyday.

Diatomaceous earth
From Wikipedia, the free encyclopedia
Jump to: navigation, search

A sample of diatomaceous earthDiatomaceous earth (pronounced /ˌdaɪətəˈmeɪʃəs ˈɝθ/), also known as DE, TSS, diatomite, diahydro, kieselguhr, kieselgur or celite) is a naturally occurring, soft, chalk-like sedimentary rock that is easily crumbled into a fine white to off-white powder. This powder has an abrasive feel, similar to pumice powder, and is very light, due to its high porosity. The typical chemical composition of diatomaceous earth is 86% silica, 5% sodium, 3% magnesium and 2% iron.

Diatomaceous earth consists of fossilized remains of diatoms, a type of hard-shelled algae. It is used as a filtration aid, as a mild abrasive, as a mechanical insecticide, as an absorbent for liquids, as cat litter, as an activator in blood clotting studies, and as a component of dynamite. As it is also heat-resistant, it can be used as a thermal insulator.

[edit] Applications

[edit] Industrial
In 1866, Alfred Nobel discovered that nitroglycerin could be made much more stable if absorbed in diatomite. This allows much safer transport and handling than nitroglycerin in its raw form. He patented this mixture as dynamite in 1867, and the mixture is also referred to as guhr dynamite.

[edit] Filtration

Individual diatom cell walls often maintain their shape even in commercially processed filter media, such as this one for swimming poolsThe most common use (68%)[citation needed] of diatomaceous earth is as a filter medium, especially for swimming pools. It has a high porosity, because it is composed of microscopically-small, coffin-like, hollow particles. It is used in chemistry under the name Celite as a filtration aid, to filter very fine particles that would otherwise pass through or clog filter paper. It is also used to filter water, particularly in the drinking water treatment process and in fish tanks, and other liquids, such as beer and wine. It can also filter syrups and sugar. Other industries such as paper, paints, ceramics, soap and detergents use it as a fulling material.

[edit] Abrasive
The oldest use of diatomite is as a very mild abrasive and, for this purpose, it has been used both in toothpaste and in metal polishes, as well as in some facial scrubs.

[edit] Pest control
Diatomite is also used as an insecticide, due to its physico-sorptive properties. The fine powder absorbs lipids from the waxy outer layer of insects' exoskeletons, causing them to dehydrate. Arthropods die as a result of the water pressure deficiency, based on Fick's law of diffusion. This also works against gastropods and is commonly employed in gardening to defeat slugs. However, since slugs inhabit humid environments, efficacy is very low. It is sometimes mixed with an attractant or other additives to increase its effectiveness. Medical-grade diatomite is sometimes used to de-worm both animals and humans. It is most commonly used in lieu of boric acid, and can be used to help control and eventually eliminate a cockroach infestation. This material has wide application in control of insects of grain storage.

Diatomaceous earth also has important pest reduction applications in the treatment of bedbugs. Bedbugs have made an unfortunate comeback and are very difficult to treat. Products with an attractant element have shown documented effectiveness with reducing and eliminating bedbug populations. Many current products are effective and safe for humans and pets.[citation needed]

Disadvantages of using diatomaceous earth for pest control include the health risk to humans (see below), and the harm it does to many beneficial insects, including predatory beetles and bugs and many detritivores.

[edit] Absorbent
Its absorbent qualities make it useful for spill clean-up and the U.S. Center for Disease Control recommends it to clean up toxic liquid spills. These qualities also lend themselves to use in facial masks to absorb excess oils.

It has been employed as a primary ingredient in a type of cat litter. The type of silica used in cat litter comes from freshwater sources and does not pose a significant health risk to pets or humans.

[edit] Thermal
Its thermal properties enable it to be used as the barrier material in some fire resistant safes.

[edit] Hydroponics
Freshwater diatomite can be used as a growing medium in hydroponic gardens.

It is also used as a growing medium in potted plants, particularly as bonsai soil. Bonsai enthusiasts use it as a soil additive, or pot a bonsai tree in 100% Diatomaceous earth. Like perlite, vermiculite, and expanded clay, it retains water and nutrients while draining fast and freely allowing high oxygen circulation within the growing medium.

[edit] DNA purification
Diatomite (Celite) can be used for the removal of DNA in the presence of a highly concentrated chaotropic agent such as sodium iodide, guanidinium hydrochloride and guanidinium thiocyanate. As with other silicates, the diatomites will remove double stranded DNA but not RNA or proteins. The DNA can be extracted from the diatomites using low ionic strength buffers, including water, at neutral to slightly alkaline pH. Crude diatomites of a uniform size must first be washed in a heated acid such as 5M HCl[1]. Calcination can further improve consistency of the material, while mild caustic treatment may improve adsorption with lower levels of chaotrophs.

[edit] Geology
Please help improve this article or section by expanding it. Further information might be found on the talk page or at requests for expansion. (January 2007)

Because diatomite forms from the remains of water-borne diatoms, it is found close to either current or former bodies of water. It is generally divided into two categories based upon source: freshwater and saltwater. Freshwater diatomite is mined from dry lakebeds and is characteristically low in crystalline silica content. Saltwater diatomite contains a high crystalline silica content, making it a useful material for filters, due to the sieve-like features of the crystals.

[edit] Specific varieties
TripoliteDakine is the variety found in Tripoli, Libya.
Bann clay is the variety found in the Lower Bann valley in Northern Ireland.
Moler (Mo-clay) is the variety found in northwestern Denmark, especially on the islands of Fur and Mors.

[edit] Climatologic importance
The Earth's climate is affected by dust in the atmosphere, so locating major sources of atmospheric dust is important for climatology. Recent research indicates that surface deposits of diatomaceous earth play an important role. For instance, the largest single atmospheric dust source is the Bodélé depression in Chad, where storms push diatomite gravel over dunes, generating dust by abrasion.[2]

[edit] Safety considerations
The absorbent qualities of diatomite can result in a significant drying of the hands, if handled without gloves. The saltwater (industrial) form contains a highly crystalline form of silica, resulting in sharp edges. The sharpness of this version of the material makes it dangerous to breathe and a dust mask is recommended when working with it.

The type of hazard posed by inhalation depends on the form of the silica. Crystalline silica poses a serious inhalation hazard because it can cause silicosis. Amorphous silica can cause dusty lungs, but does not carry the same degree of risk as crystalline silica. Food-grade diatomite generally contains very low percentages of crystalline silica. Diatomite produced for pool filters is treated with heat, causing the formerly amorphous silicon dioxide to assume its crystalline form.
In the United States, the crystalline silica content in the dusts is regulated by the Occupational Safety and Health Administration (OSHA), and there are guidelines for the maximum amounts allowable in the product and in the air near the breathing zone of workers.[3]

hmmmmm, I just had to go check the bisquick box. Nothing about DE. Even in minute quantities they would have to disclose it. Wouldn't that be the same as disclosing peanut dust? Or factories that process items that would be in contact with peanut dust? What if someone had a life-threatening allergy to DE?

Nope- I don't think it's in bisquick. Going to call the company Monday morning and inquire.

I added the wiki page for you, FOOD GRADE DE is perfectly safe. It is POOL grade that is heat treated that then creates the sillica that causes problems. When DE is added to the grains it is not listed because it is such a minute amount, usally included in the inert ingredients. They don't list every little item, if it is a less than a certain percentage it not included. Do they tell you that you have pesticides in you milk on the label, NO- but they are there. Do they tell you that you have Chinese-contaminated milk in your Hershey products NO- but they did pull some of there products when they found out. Choose what you want, it's your choice. I was just giving you information about DE. That is what this site is for INFORMATION.

this has me really confused. and rncmomx2 don't get me wrong- I think this is a very valuable point you have made. I am appreciative for this red flag. I'll get back to this subject after hopefully getting a hold of an English speaking consultant for Gen Mills Foods come Monday morn. It'll be interesting to know one way or another.

I used to clean salt-water fishtanks with DE. Always had to wear 3M mask & gloves. Curious.:upsidedown:

If you fo to this FDA site it lists items that are not required to be ont he list of ingredients click on D and look down the list DE is on it.

Formerly called Appendix A of the Investigations Operations Manual (IOM); New items are highlighted in yellow. If you are using an older web browser and you do not see the highlighting, you may download this document in PDF (270 KB) for printing.

Forward | Abbreviations | Color Additive Status List




This Food Additives Status List organizes additives found in many parts of 21 CFR into one alphabetized list. Additives included are those specified in the regulations promulgated under the FD&C Act, under Sections 401 (Food Standards), and 409 (Food Additives). The list also includes selected pesticide chemicals from 40 CFR 180 for which EPA has set tolerances in food. FDA enforces those tolerances. Within the space available, the Food Additives Status List includes use limitations and permitted tolerances for each additive. For complete information on its use limitations, refer to the specific regulation for each substance. New regulations and revisions are published in current issues of the Federal Register as promulgated. Also refer to the CFSAN website on Food Additives and Premarket Approval to review several FDA databases of additive categories. For example, EAFUS (Everything Added to Food in the United States) is a helpful reference within the limitations described at the beginning of the database.

The Food Additive Status List omits certain categories of additives. Here are the omissions:

Obviously safe substances not cited in a regulation as Generally Recognized as Safe (GRAS). You may find such substances on an FDA web site, which contains GRAS notifications received from companies since 1998, and FDA's response.
Synthetic flavoring substances in 21CFR 172.515. The CFR does not contain a complete list of permissible flavorings. Certain trade groups such as the Flavor Extract Manufacturers Association have established expert panels to evaluate and make determinations on the GRAS status of their products. If you need help in determining the acceptability of a flavoring after consulting 21 CFR 172.515, contact CFSAN Office of Food Additive Safety (HFS-200) at (301) 436-1200.
Those pending administrative determination.
Substances granted prior sanction for specific use prior to enactment of the Food Additives Amendment. For additional information on these substances, contact the CFSAN Office of Food Additive Safety (HFS-200) at (301) 436-1200.
Indirect food additives, 21 CFR Parts 175, 176, 177, & Part 178 (except that sanitizing agents for food processing equipment as listed in 178.1010 are included in the Food Additives list.) Be aware that as a result of the Food Quality Protection Act of 1996 and Antimicrobial Regulation Technical Corrections Act of 1998, EPA now has jurisdiction over sanitizing solutions applied to permanent or semi-permanent food contact surfaces, other than food packaging. To look up indirect food additives in Parts 175, 176, 177 and 178 go to FDA's "List of Indirect Additives Used in Food Contact Substances". Use it to locate the regulation in which its use is fully described. FDA has recently implemented a new way to market, called "Premarket Notification", for certain food contact substances. These notifications are effective only for the manufacturer or supplier identified in the notification. A list of effective notifications is available on the FDA website.
Color additives, 21 CFR Parts 70, 71, 73, 74, 80 & 82. Go to the Color Additives Status List following the Food Additives Status list in Appendix A.
NOTE: The Food Additives Status List is provided only as a quick look-up on the use limitations for a food additive or pesticide chemical. It is possible that mistakes or omissions could have occurred. Additionally, there may be cases where the agency has offered interpretations concerning specific provisions of the regulations. For example, in the case of boiler water additives or other minor ingredients, processing aids, or indirect additives, FDA has not objected, in certain cases, to the substitution of ammonium, calcium, magnesium, potassium, or sodium salts for each other when only one is listed in a regulation. The Food Additive Status list is updated annually, so it may not reflect the latest information. For all these reasons, take care before advising a firm that a use of a particular food additive is prohibited or otherwise limited. Read the actual regulation. If there are any doubts or if a particular situation is unclear, you or your supervisor should consult with the CFSAN, Office of Food Additive Safety (HFS-200) at (301) 436-1200, or the Division of Petition Review (HFS-265) at (301) 436-1264, or the Division of Food Contact Substance Notification Review HFS-275 at (301) 436-1162, or the Division of Biotechnology and GRAS Notice Review HFS-255 at (301) 436-1221.

Please send corrections or additions to the list to Harold Woodall, FDA/CFSAN Office of Food Additive Safety (HFS-206), 5100 Paint Branch Parkway, College Park, Maryland 20740 or e-mail them to [email protected].

Waltons, Honeyville grains, OFD, none of the folks that professionally pack food for long term storage use DE. A quick email to each of them will confirm it.



Having stored food since 1986 I have never seen a need for it. If you PACK PROPERLY from the get go, you won't NEED D.E.

BTW, someone's changed that wiki page within the last 3-5 months.

RNC, i don't think anyone is disputing the Food grade DE vs Pool grade DE subject. I would however lean to the safe side if your using a lot of it ( FOOD GRADE DE) in your preps by wearing gloves and at least a n95 dust mask. Only reason is because of the silica issue. Personally i have never used nor will.

Pool grade- bad juju- got it
food grade- use it if its what floats your boat

kind of the basic jist of it correct?:thumb:

LD3 on the wiki deal anyone can edit it. which sucks imho since it can become very biased fast!

Well, I said I'd get back to you on this issue so here's what I have found out. ZERO DE goes into any Gen Mills food products. Some of the whole grains may have trace amounts as it is stored- but it goes through a quadruple rinse and there is absolutley none that enters into the final product. This was info I received after finally getting through to a consultant. Years ago there would have been more of a course for worry- but they have state of the art washing/rinsing/prepping facilities and they claim to rigirously test and re-test all the ingredients that go into anything they manufacture. I suppose I'll just have to take their word on this.

What they did NOT confirm for me:
Any and all products intended for human consumption may / may not contain product imported from China.

It was their way of saying....there's stuff from China in our products. So beware.

If you don't pick it off the tree yourself, or milk your own cow......somewhere- something has tainted ingrediets from another country- you can bet your bottom dollar on it.
