If you do not dry pack can with oxygen absorbers, it works with wheat to put a few bay leaves into a tightly sealed container. If push comes to shove, take the buggy (they are weavel nits)/wheat outside on a breezy day, hold the container with the grain at waist height- and pour into a large container on the ground. the wind will winnow out what you do not want. The grain will not hurt you. Any grain or flour I bring home from the grocery store goes into the freezer for a week or so, there are always eggs in the product.
