What is WHO?

Before discussing the WHO guidelines for environmental monitoring, we must understand what WHO is. The World Health Organization (WHO) is basically the United Nations’ health agency. 

WHO guidelines for environmental monitoring

Here’s a breakdown of WHO’s role in society:

  • Universal health coverage: WHO advocates for everyone around the world to have access to the health care they need.
  • Public health monitoring: They monitor health risks around the globe, like disease outbreaks.
  • Health emergency response: When health crises hit, WHO helps coordinate the international response.
  • Promoting health and well-being: Their goal is to improve overall health for everyone, from pregnancy all the way through old age.

Why is environmental monitoring important?

  • Ensures product quality and safety: Monitoring helps identify and minimize contamination risks, especially in critical areas like pharmaceutical manufacturing. This protects consumers from harm.
  • Compliance with regulations: Following WHO guidelines for environmental monitoring helps companies meet regulatory requirements for their industry.
  • Continuous improvement: A risk-based approach allows manufacturers to adapt their monitoring programs based on data and identified risks, fostering an ongoing process of improvement.
  • Public health benefits: This goes beyond just pharmaceuticals. In healthcare facilities, it helps prevent the spread of infections, and in water treatment plants, it ensures clean drinking water. In various sectors, monitoring contributes to a healthier environment for the public.
  • Worker safety: Monitoring helps identify and address potential hazards in workplaces, promoting worker well-being.
  • Environmental protection: In some industries, monitoring helps track and reduce emissions of pollutants into the environment.

WHO guidelines for environmental monitoring: a risk-based approach

The WHO emphasizes a risk-based approach to environmental monitoring. This means tailoring the monitoring program to the specific risks associated with the product and its manufacturing process. Key factors considered include:

  • Product Type: Sterile products necessitate stricter monitoring than non-sterile ones.
  • Manufacturing Process: Aseptic manipulation processes require more intensive monitoring compared to those with lower contamination risks.
  • Room Classification: The WHO guidelines reference ISO 14644 standards for cleanroom classification. Higher air cleanliness levels demand more frequent monitoring.

Elements of an effective monitoring program

The WHO guidelines outline several key elements for an effective environmental monitoring program:

  • Program Design:
    • A documented program outlining the monitoring strategy, including locations, frequency, and parameters to be monitored.
    • A risk assessment to identify critical areas and processes requiring the most stringent monitoring.
    • Selection of appropriate monitoring methods based on the parameters of interest (e.g., air sampling, surface swabbing).
    • Establishment of alert and action levels for each parameter. These levels define acceptable limits for contamination, and exceeding these triggers corrective actions.
  • Monitoring Parameters:
    • Microbial Monitoring: Detecting the presence and types of microorganisms in the environment, including monitoring air, surfaces, and personnel.
    • Non-viable Particulate Monitoring: Measuring the concentration and size of airborne particles. High levels of particles can indicate potential contamination risks.
    • Environmental Conditions: Monitoring factors like temperature, humidity, and pressure differentials that can impact product stability and microbial growth.
  • Monitoring Methods:
    • Airborne Microorganisms: Techniques like active air sampling (using air samplers) and settle plates (measuring airborne microorganisms landing on a surface over time) are employed.
    • Surface Microorganisms: Swabbing surfaces with sterile swabs to collect samples for analysis.
    • Non-viable Particulates: Using particle counters to measure particle size and concentration.
    • Environmental Conditions: Utilizing calibrated instruments like thermometers, hygrometers, and pressure gauges.
  • Data Management and Corrective Actions:
    • Implementing a system for recording, analyzing, and trending monitoring results.
    • Establishing procedures for investigating deviations from alert and action levels.
    • Taking corrective actions to address identified contamination sources and prevent future occurrences.
    • Reviewing and updating the monitoring program based on ongoing data analysis and risk assessments.
