What is the difference between Food grade and Feed grade DE. I am wanting to clean my coop and put DE down but, it is expensive. The guy at the feed store said he can get me the same size bag for 10 dollars cheaper but, it is Feed grade and not Food grade. What is the difference???????

There is no difference.
I think he's confused

I believe that feed grade has calcium bentonite in food grade. I have feed grade DE in addition to food grade DE. The only difference is the calcium bentonite which serves as an absorbent. It is cheaper because part of the mixture is bentonite, not DE.

Presumably, the bentonite helps keep the feed dry.

Products that are labeled Food Chemical Codex Grade have met high standards and are considered safe however, in the case of diatomaceous earth, this term does not suggest that the product is safe or registered for human consumption.

Food Chemical Codex Grade diatomaceous earth products may be approved for use as a filtering and processing aid in the food industry, as long as the substance is removed from final goods offered for sale. In the United States, FCC complaint DE products are regulated by each state for use in livestock feed as an anti-caking agent and flow aid (in amounts not to exceed two percent of total diet).
