2. Bird and animal droppings can cause pulmonary fibrosis.
Bird and animal droppings have a foul smell to them and if they are inhaled for a long time it can affect the lungs. For instance, dogs are unable to cover their bowel movement, so if it’s not cleaned up by their owner, it will smell. If a person has to be outside for a while, it is best to wear a mask.
Most people don’t wear a mask if they’re just outside gardening or mowing the lawn. Bird droppings can have a foul smell, especially if their droppings are huge. It is even worse if a bird decides to have their droppings fall on you. Take the piece of clothing off, if you’re at home and wash it in hot water. If you are unable to wear a mask, cover your mouth and nose until you’re away from the area.
