1. Raw Materials:
A. Water:
Used in formulations can be a significant source of microbial contamination if not properly treated.
B. Active Pharmaceutical Ingredients (APIs):
May harbor contaminants from their source or during processing.
C. Excipients:
Ingredients like fillers, binders, and stabilizers can introduce microbes if not properly handled.
2. Manufacturing Environment as Sources of Microbial Contaminants:
A. Air:
Airborne contaminants can settle on surfaces and products.
B. Surfaces and Equipment:
Inadequately cleaned or sanitized surfaces and equipment can harbor microbes.
C. Personnel:
Human operators can introduce contaminants through skin, clothing, or respiratory droplets.
3. Packaging Materials:
A. Containers and Closures:
Can introduce contaminants if not sterile or if compromised during storage.
B. Packaging Process:
Can lead to contamination if not conducted under sterile conditions.
4. Storage and Distribution:
A. Storage Conditions:
Improper temperature and humidity can promote microbial growth.
B. Transportation:
Contaminated transportation environments can introduce or promote the growth of microbes.
5. Handling and Use:
A. Consumer Handling:
Improper handling by consumers can introduce contaminants.
B. Healthcare Settings:
Contaminated environments or improper handling during administration can lead to contamination.
These are all the Sources of Microbial Contaminants
