Good point.
I use natural fly predators to reduce the deer flies and nematodes in standing water for mosquito control. Both are much safer to use around grazing horses.
One big thing many people do not think of with organic vegetables is you still need to wash them because of pathogens that can get on the food. Somehow organic means CLEAN to them. Animal/bird droppings, etc. still happen on organic farms.
Even indoor grown hydroponic food items should still be washed because of pathogens transmitted from handling.
