Cob: Diatomaceous Earth Types

[sd_fenton at cox.net]

Just to close up the discussion on the types of diatomaceous earth since I 
started the whole thing:          ; )

I mentioned to be sure to use food grade diatomaceous earth in regards to 
cob, or, I really believe, in *any* case, because of what people have 
responded with already. Silica is very dangerous to breathe. Therefore, in 
my opinion anyone working on a cob mix should use "food grade", as much of 
it is bound to be inhaled in the process.

Off topic: At the risk of repeating some of the info on the links Amanda 
Peck, J. Frost and I provided, food grade is also safe to feed to livestock 
to limit intestinal parasites. It's also safe to set out in a pan for the 
farm fowl to fluff in to remove surface parasites, etc.

Check your locally owned feed & seed store or I can get the manufacturer 
name and number off the sack at mine.
