Airborne microorganisms are biological airborne from the air as they are generated through aerosols. These aerosols are suspensions of microscopic solid or liquid particles in the air that can contain bacteria, viruses, and fungi and can contaminate food products or food contact surfaces.
Biogenic aerosols are those which come from living things. This can include organic chemicals such as limonene, which are emitted by plants and react in the atmosphere to form aerosols, as well as other debris such as pollen, spores, and microbes.
