Fungi in Cleanrooms: Types, Origins, and Decontamination Strategies

Cleanrooms and controlled environments are at risk from fungal spores, should they enter the facility. Fungi can present health hazards to operators and pose potential contamination risks to  medicinal products. The presence of fungi in the processing areas of pharmaceutical and healthcare  products manufacturing facilities is normally regarded as an indication of a control breakdown, such  as one relating to air handling or with the transfer of materials (or people) into the manufacturing area. The risk exists because most fungi produce spores, for reproduction or for survival, and such spores are relatively easy to disperse in the form of bioaerosols. These biologically dynamic particles can cover relatively wide distances and, unlike bacterial spores, fungal spores are found in relatively high numbers. The risk of spore dispersal can be enhanced based on air.

  1. The sterilizer itself likely being the main source of moisture dispersement responsible for mold spore growth.
