Measurement of Airborne Bacterial Colonies Upon Cleaning a Factory Worker Area

Background: Bioaerosols are airborne microorganisms that consist of dust particles formed from organisms or their remains. Indoor air could contain a higher quantity of pollutants than outdoor air. Indoor air pollution is a primary concern that can lead to health issues for workers. Considering the biological exposure in the workplace, it is crucial to evaluate the impact of cleaning workers' areas by measuring the concentration of airborne bacterial colonies before and after the cleaning process.Objective: To determine the effect of cleaning workers' areas on the prevalence of airborne bacterial colonies.Method: Determine the number of employee workspaces utilized for service, organize supplies and equipment for the assessment of airborne bacterial colonies, and conduct an evaluation of the airborne bacterial colony count following the cleanliness of employee workspaces.Results: Employee workspace cleaning is conducted continually without a specified timeframe, but production equipment operates around the clock. The smallest number of colonies observed in the packing room was 5, but the maximum recorded in the production administration room was 248. The increase of airborne microorganisms is associated with staff activity, the number of personnel, and spatial dimensions. Macroscopically, the multiplication of airborne bacteria was accompanied by the observation of fungal development in the baling room and warehouse. The staining results indicate that the Gram-positive rods likely belong to the Bacillus or Clostridium genera. The number of airborne colonies is associated with activity levels, workforce size, spatial dimensions, and the bacterial species from the Bacillus or Clostridium genera.
