Contamination During the Freezing and Thawing Process

Contamination Analysis Microbial Contamination (Bacterial, Fungal, Viral) Chemical Contamination (Solvents, Heavy Metals, Pesticides) Cross-Contamination (from Equipment or Production Environment) Physical Contamination (Glass, Metal Particles, Rubber Fragments) Endotoxin Contamination (Pyrogens) Particulate Contamination (Dust, Fibers, Foreign Particles) Water Contamination (Bacterial, Chemical, Physical Impurities) Contamination from Packaging Materials (Plasticizers, Residual Solvents) Contamination from Raw Materials (Contaminated Excipients) Contamination from Inactive Ingredients Environmental Contamination (Airborne Contaminants, HVAC Systems) Leachables and Extractables from Packaging Materials Cross-Contamination during Bulk Manufacturing Contamination from Improper Storage Conditions Contamination during Handling and Transportation Biological Contamination (Proteins, DNA) Contamination from Human Error (Poor Hygiene, Improper Handling) Microbiological Contamination in Water for Injection (WFI) Impurities from Previous Drug Batches Microbial Testing (Total Aerobic Count, Yeast and Mold Count) Endotoxin Testing (LAL Test, Recombinant Factor C Assay)

Decreased Efficacy of the Drug Potential Toxicity from Chemical Contaminants Risk of Infections from Microbial Contaminants Degradation of Drug Formulation Quality Reduction in Shelf Life and Stability Alteration of Drug Pharmacokinetics Unwanted Side Effects or Adverse Reactions in Patients Harmful Reactions Between Contaminants and Active Ingredients Safety Hazards from Contaminated Raw Materials Increased Risk of Drug Product Recalls Compliance Issues with Regulatory Standards Negative Impact on Brand Reputation Increased Manufacturing Costs Due to Contamination Control Delays in Production or Market Launch Potential for Cross-Contamination Between Drug Batches Product Safety Failures Leading to Health Risks Contamination of End Product During Packaging Product Quality Issues
