Microbial contamination of money sorting facilities.

Area of Science:

• Microbiology
• Occupational Health
• Environmental Science

Background:

• Banknotes and coins are frequently handled and can harbor microbial contaminants.
• These contaminated items can act as vectors for spreading microorganisms.

Purpose of the Study:

• To assess microbial contamination levels in money sorting facilities.
• To identify potential health risks for employees exposed to these contaminants.

Main Methods:

• Bioaerosol sampling using a 6-stage Andersen impactor.
• Surface sampling via the swab method.
• Taxonomic identification of isolated bacterial and fungal species.

Main Results:

• Money sorting facilities are active sources of microbial emissions.
• Airborne microbial concentrations were within acceptable limits, indicating effective ventilation.
• Tabletop surfaces and currency showed high levels of bacterial and fungal contamination, exceeding recommended purity standards.
• Identified microorganisms included pathogenic bacteria and fungi, posing a health risk.

Conclusions:

• Employees in money sorting facilities face exposure to potentially harmful microorganisms.
• Implementing stringent hygienic practices is crucial to mitigate contamination and secondary emission from currency and surfaces.
• These measures are essential for protecting employee health in such environments.
