Working with bird or bat droppings poses potential exposure to serious infectious diseases for workers. The risk increases when disturbing large accumulations of dried droppings, although small amounts carry a lower risk. Diseases such as Histoplasmosis, Cryptococcosis, Psittacosis, and gastrointestinal illnesses are associated with these droppings.

Workers at risk include those involved in cleaning, renovating, or demolishing structures where birds or bats roost, spelunkers, pest control specialists, maintenance workers, and those working with soil in bird or bat-inhabited areas.

Exposure management is crucial, aiming to eliminate or minimize risks. Preventative measures include deterring birds, inspecting for droppings regularly, and cleaning promptly. When cleaning large accumulations, it's important to manage exposure to dust and aerosols by using dust barriers, ventilation controls, and wetting droppings during removal.

Personal hygiene practices are essential, including thorough handwashing, using hand sanitizers, covering cuts, avoiding face touching, and washing or showering after work. Workers should wear appropriate personal protective equipment (PPE), such as particulate respirators, gloves, protective clothing, eyewear, and boot covers during cleanup.

Providing information, training, and supervision to workers regarding health risks, safe work procedures, PPE use, and handwashing practices is crucial. Additionally, facilities like washing stations, first aid, clean eating areas, and drinking water should be provided to ensure workers' well-being.
