Use at least 2 feet of composting material for younger animals.

Remove any large bones before spreading compost on fields.
"We looked at barbiturates used in euthanasia drugs, and those are breaking down in composting," Bonhotal
"Wormer [ivermectin] is breaking down pretty well in the environment," she
