Strict contamination control safeguards product safety, compliance, and brand reputation.
What Is Cross-Contamination?
Cross-contamination occurs when one product, raw material, or substance unintentionally comes into contact with another. This can happen through shared equipment, airborne particles, improper cleaning, personnel handling, or inadequate material segregation.
