DE Help!!

[MamaChick0708]

Hi guys so Im wondering if I just made a fatal error, I just realized the bag of DE I bought and lightly sprinkled in my coop is NOT food grade, should I be freaking out? Is one application going to harm the chickens. I didnt use a lot just a little sprinkle and I do the deep litter method so I was trying to figure out if I just turned the bedding over if they would be okay.

Any thoughts would be great Im new to this.

Also the chickens are out in the run and have not come in contact with the DE yet.
