I purchased some DE online; ad says Food Grade (FG), receipt says FG but it does not say so on the bag, nor does it say Pet Safe as reviewed on Amazon (same brand). Can I be sure it is actually FG? It seems like it usually says so on the package. It's called "Insect Dust", says "do not contaminate water, food or feed by disposal", and the word "pesticide" is mentioned 2x in the hazard section. It contains 85% DE Silocon Dioxide, 10% other element dioxides & 5% moisture. It's St. Gabriel's Organics. I am very suspicious that it's actually FGDE. BTW I have since found the 50 lb bag of FGDE at a farm store. Thanks for your expertise.
