Laura Ward, BSc, shares perspectives on bioaccumulation of chemicals in foods we and our pets eat. Specifically, she says glyphosate, a non-selective herbicide applied to the leaves to kill plants and grasses, is found in a vast amount of human and dog food. She notes glyphosate does not accumulate in meat from animals as it does in plants.
Wards is not trying to cause concern, but simply to explain the current situation of glyphosate use in farming crops and how this herbicide can be found in dog foods.
