Are pigeon droppings a health hazard?
Any bird droppings or excrements of animals including humans can contain potentially hazardous components like bacteria, worms or fungi. Bird droppings can cause pulmonary diseases or allergies, if the droppings would be scrapped off and the resulting dust is being inhaled frequently or for longer periods of time by a person with a weakened immune system. Pigeon droppings are a valuable fertiliser though, if dried and put in your garden.
