Due to the fact that diatomaceous earth is a product used in animal feed, its label requires a guaranteed analysis to advise consumers of the product’s nutrient content. Pet food labels are required to guarantee minimum percentages of crude protein and fat and maximum percentages of crude fiber and moisture (in this context, “crude” refers to the method of measuring the nutrient, not to quality). Guarantees stated in terms of “minimums” suggest that no less than the amount listed will be found in the product if tested at any time while “maximums” assure that no more than the amount listed will be found. Minimums and maximums are used as each batch will vary in its composition.
As diatomaceous earth does not and is not intended to provide protein, fat or fiber, it is exempt from these guarantees. However, in all cases, moisture guarantee is required. In addition, although often optional, the state of Texas requires diatomaceous earth products to guarantee ash content.
What is Ash Content?
Often this is mistaken as volcanic ash or the type of ash that results from burning however, in this case, ash refers to the inorganic mineral elements found in the product. This is used to signify to producers that the product does not have any nutritional value but, rather, contains up to 95% inorganic mineral elements.
