Occupational exposure to bioaerosols during monk parakeet nest removal in urban parks.

Occupational removal of monk parakeet nests in urban parks exposes workers to high levels of fungi, bacteria, and endotoxin, with endotoxin exceeding health guidance values.

• Why it matters: Understanding bioaerosol exposure during invasive species management is crucial to protect worker health and prevent respiratory risks associated with microbial pollutants.
• What they did: Researchers analyzed nest material and air samples from nest removal sites for microbial content, identifying 43 fungal and 91 bacterial species, including RG2 pathogens, and measuring inflammatory potential.
• The result: Findings reveal nests as a significant source of airborne microorganisms and endotoxin, highlighting the need for protective measures during nest removal to mitigate inflammatory and allergic respiratory risks.
