Crystalline Silica Content?

Could you advise the crystalline silica content % in Diatomaceous Earth? Basically wondering if this is Food Grade (safer for breathing in etc). Thanks.


We are not sure.  You can try contacting the manufacturer and they may be able to tell you, but what we can tell you is that alpine dust nor any DE dust we carry is food grade.  It is pest control grade and not meant for any consumption.
