Food grade diatomaceous earth (DE) and diatomaceous earth products have seen a surge in popularity among health enthusiasts, gardeners, and pet owners alike. The first products containing diatomaceous earth were registered in 1960 to kill crickets, fleas, ticks, spiders, and mites. Right now, diatomaceous earth products are registered in a multitude of pesticide products. As a versatile product with a wide array of uses, ranging from being used in supplements to an effective pest control solution, its appeal has grown rapidly. But what exactly makes food-grade diatomaceous earth so special? In this post, we’ll explore what DE is, how it’s produced, its practical benefits, and how it can be safely used.



What is Food Grade Diatomaceous Earth and Why is it So Popular?


Diatomaceous earth is a naturally occurring, fossilized mineral made from the remains of tiny, aquatic organisms called diatoms. Many think it is derived from a type of rock sand. But it is derived from a type of plant. Over time, these diatoms accumulate in the sediment of rivers, lakes, and oceans and form a chalky, silica-rich substance. Food-grade diatomaceous earth is a specific type that is purified and safe for animal consumption. Unlike its industrial counterpart used in pool filters, food-grade DE has a significantly lower level of crystalline silica, making it non-toxic and safe for a variety of uses. Our food grade diatomaceous earth is amorphous silica, which means it is derived from a fresh water source.


Definition of Food Grade Diatomaceous Earth

Food grade diatomaceous earth (DE) is a natural, fine powder made from the fossilized remains of microscopic aquatic organisms called diatoms. It is specifically processed to meet safety standards for human and animal consumption. Unlike industrial-grade diatomaceous earth, food grade DE contains less than 1% crystalline silica, making it non-toxic and safe to use as a health supplement, in food processing, or as a natural pesticide for plants, pets, and livestock. Its high silica content and absorbent properties contribute to its uses in detoxification, digestive health, and pest control.

Composition of Food Grade Diatomaceous Earth

  • Wear Protective Eyewear: DE particles can irritate the eyes if they come into contact with them. Wearing protective goggles when handling or applying DE helps to avoid this irritation.


3. Keep DE Dry for Maximum Effectiveness

  • Store in a Cool, Dry Place: DE should be kept dry to retain its effectiveness as a natural pesticide and absorbent. When DE gets wet, its ability to dehydrate pests and act as a cleaning agent is diminished.

  • Reapply After Rain: If using DE outdoors for pest control, it will need to be reapplied after rain or moisture exposure to maintain its effectiveness.


4. Use Food Grade DE Only

  • Ensure Proper Grade: Only use food grade diatomaceous earth for health and household purposes. Industrial or pool-grade DE contains high levels of crystalline silica, which is hazardous if inhaled and not safe for ingestion. Always check the label to ensure you are using food grade DE, especially for ingestion or around pets and livestock.


5. Handle with Care Around Pets and Children

  • Supervise Application: When using DE around pets or children, be cautious during application to avoid them inhaling or coming into contact with the dust. While food grade DE is non-toxic if ingested in small amounts, it can still cause respiratory irritation if inhaled in large quantities.

  • Keep Pets Away During Application: For pets, it's best to keep them away from the treated areas during and immediately after applying DE to avoid respiratory issues. Once the dust settles, it is safe for pets to return to the area.


6. Avoid Overuse in the Diet

  • Follow Recommended Dosage: If taking DE as a supplement, it’s important to follow the recommended dosage, usually 1 teaspoon to 1 tablespoon per day mixed with water or other liquids. Overconsumption can lead to constipation, dehydration, or gastrointestinal discomfort due to its absorbent properties.


7. Prevent Skin Irritation

  • Wear Gloves: While DE is not harmful to the skin, its drying and mildly abrasive properties can cause irritation or dryness if it comes into prolonged contact with skin. Wearing gloves can help prevent any skin discomfort.


8. Wash Hands After Handling

  • Avoid Ingesting by Accident: After handling DE, wash your hands thoroughly, especially before eating or touching your face to avoid accidentally ingesting any DE dust.


9. Consult a Doctor if Needed

  • Health Concerns: If you're unsure about using DE as a supplement or for health purposes, consult a healthcare provider to discuss whether it is appropriate for your individual health needs, especially if you have existing respiratory conditions or sensitivities.


10. Use as Directed for Pests

  • Proper Application for Pest Control: When using DE for pest control, it should be applied as a thin, even layer. Piling DE in large amounts may be less effective and wasteful. It's most effective when applied to areas where pests travel or nest.

By wearing protective gear, applying DE in well-ventilated areas, and ensuring you use the food grade version, you can take full advantage of its benefits while keeping yourself, your family, and pets safe.



How is Food Grade Diatomaceous Earth Produced?


diatomaceous earth mine

The process of creating food grade diatomaceous earth begins with mining the fossilized remains of diatoms from freshwater sources. After extraction, the material is milled into a fine powder. The product is then carefully tested to ensure that it contains less than 1% crystalline silica, which makes it safe for use around humans, pets, and even in food production. This careful preparation ensures food grade DE remains highly absorbent, non-toxic, and retains its essential mineral content, especially silica, which plays a crucial role in its health benefits.



Source of Food Grade Diatomaceous Earth

The source of food grade diatomaceous earth (DE) is fossilized remains of diatoms, which are microscopic, single-celled algae that lived in oceans, lakes, and rivers millions of years ago. These diatoms had cell walls made of silica, a natural mineral. Over time, the silica-rich skeletons of these organisms accumulated in large deposits on the seabed or lakebeds, eventually fossilizing into a soft, chalky sediment known as diatomite or diatomaceous earth.


How Food Grade DE Is Sourced:


  1. Mining: The diatomite deposits are mined from ancient lake beds and seabeds, primarily found in various regions worldwide, including the U.S. (especially in California and Nevada), Mexico, China, and parts of Europe.


  2. Processing: After mining, the diatomite is processed by milling it into a fine, white powder. For food grade DE, it undergoes specific treatments to remove impurities and ensure a very low crystalline silica content (less than 1%), making it safe for human and animal consumption.


Food grade DE is distinct from other types, such as pool grade DE or filter grade diatomaceous earth, which undergoes further treatment that increases its crystalline silica content, making it hazardous for health purposes.

Extraction Process

The extraction process for food grade diatomaceous earth (DE) involves several steps that ensure it is safe for human and animal consumption. Here's an overview of how DE is mined, processed, and refined into its food grade form:


1. Mining


  • Locating Deposits: Diatomaceous earth is found in large deposits of diatomite, which are often located in ancient lake beds, seabeds, and riverbeds. These deposits formed over millions of years from the fossilized remains of diatoms, which had silica-based cell walls.


  • Extraction: Once a deposit is identified, it is mined using surface mining techniques. The mining process usually involves the removal of overburden (the top layer of soil and rock) to expose the diatomite deposits. This is done carefully to avoid contamination and preserve the purity of the DE.


2. Crushing and Drying


  • Initial Crushing: The extracted diatomite is transported to processing facilities, where it is crushed into smaller pieces to make it easier to handle.


  • Drying: The diatomite is then dried to remove any moisture. This is a critical step because moisture can reduce the absorbent and abrasive properties of DE. Drying is typically done in large, industrial dryers.


3. Milling


  • Grinding: After drying, the diatomite is finely ground into a powder. For food grade diatomaceous earth, the grinding process is carefully controlled to produce a uniform, fine powder. The finer the powder, the more effective it is in applications like health supplements, pest control, and filtration.


  • Screening: The powder is screened and classified to ensure the correct particle size. Any larger particles are sent back for further grinding until the desired fine consistency is achieved.

Purification Process

The purification process of food grade diatomaceous earth (DE) is a key step in ensuring that it is safe for human and animal consumption. The purification process primarily focuses on removing impurities and reducing the crystalline silica content, making it suitable for use as a supplement and for other natural applications like pest control. Here's an overview of the purification process:


1. Crushing and Initial Screening


  • After mining, the diatomite is first crushed into smaller pieces. This helps to separate the raw material and remove larger unwanted rocks or debris.


  • Screening is done to remove large, unwanted particles such as gravel, stones, or organic matter that may have been collected during the mining process. This initial step helps ensure that the raw material is of a consistent quality before moving into further refinement.


2. Drying


  • The crushed diatomite is then dried in large industrial dryers to remove any moisture. The drying process ensures that the diatomaceous earth retains its natural absorbent and abrasive properties, which are important for many of its applications, such as detoxification and pest control.


  • Drying also helps reduce the risk of mold or bacteria forming in the material, which could occur if there is residual moisture in the diatomite.


3. Fine Grinding and Milling


  • Once dried, the diatomaceous earth is finely ground into a powder. This grinding process helps break the diatomite into fine, uniform particles suitable for food grade DE.


  • The fine grinding also improves the surface area and absorbency of the material, making it more effective for applications like toxin absorption and natural pest control.


4. Separation of Impurities


  • During this stage, the material undergoes further separation and filtration to remove any remaining organic matter, other minerals, or contaminants.


  • Magnetic or air classification methods are often used to separate heavier impurities from the fine DE particles.


  • Any excess clay, sand, or other sediment is eliminated, ensuring that the final product is pure and free of contaminants.


5. Crystalline Silica Reduction


  • One of the most important aspects of the purification process is ensuring that food grade DE has low crystalline silica content (less than 1%). Crystalline silica can be harmful when inhaled, and the goal is to minimize its concentration for safe use.


  • This reduction is typically achieved through mechanical or thermal processes that either remove or minimize the crystalline silica content during the milling and filtration stages.

Grading Process

The grading process of food grade diatomaceous earth (DE) is crucial for ensuring that the product meets specific safety and quality standards for human and animal consumption. Grading involves sorting, testing, and classifying DE based on its purity, silica content, particle size, and suitability for various applications. Here's an overview of the grading process:


1. Initial Crushing and Drying


  • Crushing: After mining, diatomaceous earth is first crushed into smaller pieces to facilitate handling and further processing.


  • Drying: The raw diatomite is dried to remove moisture, which helps in the later stages of grading by ensuring consistent texture and absorbency.


2. Particle Size Sorting


  • Screening: The material is passed through screens or sieves to separate it by particle size. For food grade DE, fine particles are essential to ensure the product is suitable for ingestion and other delicate applications like skin and hair care.


  • Uniformity: The goal is to produce a fine, uniform powder that can be safely consumed and applied for its various uses (such as detoxification and pest control).


3. Impurity Removal


  • Magnetic Separation: The DE may undergo magnetic separation to remove metallic impurities or other heavy particles that could affect its purity.


  • Filtration and Air Classification: Advanced filtering systems are used to remove sand, clay, and other impurities. Air classification techniques can be used to further refine the material by separating heavier, unwanted particles from the fine DE powder.


4. Testing for Crystalline Silica Content


  • Silica Content Testing: One of the most critical steps in the grading process is testing the crystalline silica content. For food grade DE, the content of crystalline silica must be less than 1%, as higher levels can pose health risks if inhaled.


  • Samples of the processed DE are tested in laboratories to ensure they meet these strict safety standards.


  • Non-Crystalline Silica: Food grade DE primarily consists of amorphous (non-crystalline) silica, which is safe for ingestion and skin contact.


5. Purity and Quality Control

Effectiveness in Pest Control and Detoxification

When comparing the effectiveness of food-grade diatomaceous earth (DE) to non-food-grade DE in two key areas—pest control and detoxification—there are significant differences in terms of safety, but the effectiveness can vary based on the application. Here’s a breakdown:


1. Pest Control


Both food-grade and non-food-grade DE can be effective for pest control due to their similar physical properties. However, food-grade DE is generally preferred for household and organic pest control applications because of its safety for humans, pets, and the environment.


Food-Grade Diatomaceous Earth:


  • Safe for Use Around Food, Pets, and Humans: The primary advantage of using food-grade DE for pest control is its safety. It can be applied in areas where food is prepared, stored, or consumed, as well as around pets and children without posing a health risk.


  • Effective for Killing Insects: Food-grade DE works by physically damaging the exoskeletons of insects, causing them to dehydrate and die. It is effective against a wide range of pests, including ants, bed bugs, fleas, cockroaches, and beetles.


  • Versatile Application: Since it’s safe for use indoors and outdoors, food-grade DE can be spread in gardens, kitchens, pantries, and pet bedding areas without any risk of contamination.


  • Organic Pest Control: Food-grade DE is often used in organic gardening and farming, where the use of chemical pesticides is restricted.


Non-Food-Grade Diatomaceous Earth:


  • Effective, But Not Safe for Use Around Food or Pets: Non-food-grade DE is also effective for pest control, as it works similarly by dehydrating insects. However, it should not be used in areas where food is handled, stored, or prepared. It is more appropriate for industrial or outdoor pest control, where exposure to humans or animals is minimal.


  • Toxic to Pets and Humans: Because of its higher crystalline silica content and potential chemical additives, non-food-grade DE can pose inhalation hazards or other health risks if used in close contact with humans or animals. It is not safe for use in homes or areas with pets.


Overall in Pest Control:


  • Both forms of DE are equally effective in killing pests, but food-grade DE is far safer for general use, especially in homes, around food, and with pets or children. Non-food-grade DE is reserved for industrial applications or outdoor use where safety risks are less concerning.


2. Detoxification (Human and Animal Health)


This is an area where only food-grade diatomaceous earth is applicable. Non-food-grade DE is not safe for detoxification purposes and should never be ingested or used in ways that involve direct human or animal contact.


Food-Grade Diatomaceous Earth:


  • Internal Detoxification: Food-grade DE is often marketed as a natural detoxifying agent. When ingested in small amounts, it is believed to help cleanse the digestive system by:


    • Absorbing Toxins: The porous structure of DE can bind to harmful bacteria, heavy metals, and toxins in the digestive tract and remove them through normal excretion.


    • Improving Gut Health: Some claim that DE can improve gut health by promoting better digestion and cleaning out unwanted waste materials, though scientific evidence supporting these claims is limited.


  • Parasite Control in Animals: Farmers and pet owners sometimes add food-grade DE to animal feed as a natural method to control internal parasites like worms in livestock or pets. The sharp microscopic edges of DE can damage the outer layers of parasites, leading to their death, without harming the host.


  • Mineral Supplementation: Food-grade DE contains trace amounts of silica, which is essential for healthy bones, skin, hair, and nails. Some people take it as a dietary supplement to boost silica intake.


Non-Food-Grade Diatomaceous Earth:


  • Not Safe for Detoxification: Due to its higher crystalline silica content and potential chemical contaminants, non-food-grade DE should never be ingested. Its use for detoxification or health purposes can lead to serious health risks, including respiratory issues and potential damage to internal organs if ingested.

Food-grade diatomaceous earth (DE) is a natural product with a variety of uses, from pest control to health supplements. Many people wonder about its safety and effectiveness for both humans and pets. Is it safe to consume? Can it be used to treat pets? How does it work as a natural insecticide? Additionally, there are questions about its potential health benefits for humans, as well as possible side effects. In this FAQ section, we’ll address these common questions to help you understand the full range of uses and safety considerations for food-grade DE.



Is it Safe to Consume?

Yes, food-grade diatomaceous earth (DE) is generally considered safe to consume in small amounts. It contains a high concentration of silica, a mineral that can support bone, hair, skin, and nail health. Many people use it as a dietary supplement, claiming benefits like improved digestion and detoxification.


However, it’s important to ensure you are using only food-grade DE, as non-food-grade DE contains higher levels of crystalline silica, which is harmful when ingested. It's also essential to consume DE in moderation, as overconsumption may cause digestive discomfort, dehydration, or irritation to the gastrointestinal tract. Always consult a healthcare professional before adding it to your diet.

Can it Be Used For Pets?

Yes, food-grade diatomaceous earth (DE) can be safely used for pets in several ways. It is commonly used as a natural remedy for controlling internal parasites like worms when mixed into their food. Its sharp, microscopic particles help damage the outer layer of parasites, leading to their death, without harming the pet.


It can also be applied topically to your pet’s fur to combat external pests like fleas, ticks, and mites. Since food-grade DE is non-toxic, it's safe if pets ingest small amounts while grooming themselves. However, avoid letting your pets inhale the dust, as it can irritate their respiratory systems. Always consult a vet before using DE on pets, especially for internal use.

How Does it Work as a Natural Insecticide?

Diatomaceous earth (DE) works as a natural insecticide by physically damaging the exoskeletons of insects rather than relying on chemicals. DE is composed of tiny, sharp, fossilized algae particles (diatoms) that are abrasive and highly absorbent.


When insects like ants, fleas, or bed bugs come into contact with DE, the sharp particles pierce and scrape their exoskeletons. This causes the insects to lose moisture and dehydrate, ultimately leading to their death. DE’s desiccating effect works on a wide range of pests, making it effective for pest control without the use of toxic chemicals.


Since it’s non-toxic to humans and animals, food-grade DE is safe to use in homes, gardens, and around food. However, it must remain dry to be effective, as moisture reduces its ability to dehydrate insects.

Can it Be Used For Human Health Benefits?

Yes, food-grade diatomaceous earth (DE) is often used for potential human health benefits, particularly as a supplement. Some of the common claims include:


  1. Digestive Health: It’s believed to help with digestion by acting as a gentle internal cleanser, removing waste, toxins, and pathogens from the digestive tract.


  2. Detoxification: DE is thought to absorb harmful substances like heavy metals, bacteria, and toxins, helping to flush them out of the body through normal excretion.


  3. Improved Hair, Skin, and Nails: DE contains silica, a mineral that can support collagen production, contributing to healthier hair, skin, nails, and even joints.


  4. Parasite Control: Some people use DE as a natural way to combat internal parasites, though evidence is mostly anecdotal.


While many people report positive results, the scientific evidence supporting these benefits is limited, and DE should be consumed in moderation. As with any supplement, it’s best to consult a healthcare provider before using it, especially if you have existing health conditions.

What are the Potential Side Effects?

While food-grade diatomaceous earth (DE) is generally considered safe for consumption in small amounts, there are some potential side effects to be aware of:


1. Respiratory Irritation


  • Inhalation of DE dust can irritate the respiratory tract, causing coughing or shortness of breath. This is especially a concern if large amounts of dust are inhaled over time. Even though food-grade DE has low crystalline silica content, it’s best to avoid breathing in the fine particles.


2. Digestive Discomfort


  • Overconsumption of DE may lead to digestive issues such as bloating, gas, constipation, or stomach discomfort. Since DE is absorbent, it can also dehydrate the digestive system if not taken with enough water.


3. Dehydration


  • DE is highly absorbent, so consuming large amounts without sufficient water can lead to dehydration. Always drink plenty of water when taking DE to prevent dryness in the digestive tract.


4. Skin Irritation


  • If DE comes into contact with the skin, its abrasive nature can cause dryness or irritation, especially with prolonged exposure. This is more of a concern when handling DE in powdered form.


5. Potential Mineral Imbalance


  • In theory, excessive use of DE could interfere with the body’s mineral balance, especially since it absorbs certain substances. Long-term, high-dose use could potentially cause issues with nutrient absorption.


6. Possible Interaction with Medications


  • DE might interact with certain medications by absorbing them in the digestive system, reducing their effectiveness. It's important to consult a healthcare provider if you’re on any medications before using DE.


In general, food-grade DE should be used in moderation and with plenty of water. If you have any underlying health conditions or are pregnant or nursing, consult a healthcare professional before use.
