Red Lake Earth (RLE) is a food chemical codex grade diatomaceous earth product that is registered for use in livestock feed as an anti-caking and flow agent (not to exceed 2% of total diet).
This product does not have an expiration date. As long as it is stored in a cool, dry area, it is good for an indefinite period of time. In fact, Red Lake Earth can even become wet and be used after it is left to dry! Once dry, the product will return to its natural state and continue to work as it did before it became wet.
A date stamp can be found on RLE packaging however this stamp is not an expiration date but rather the day that the product was packaged.
Red Lake Diatomaceous Earth is an all natural product. The age of the product does not affect its ability to function therefore a new bag of RLE will be just as effective as an older bag.
