Cross-contamination in pharmacy practice refers to the unintended transfer of harmful substances to medications during compounding or dispensing. This can occur when equipment, surfaces, or hands carrying contaminants come in contact with medications, leading to potential patient harm or compromised drug efficacy.

Understanding cross-contamination is essential because it emphasizes the importance of hygiene protocols, proper use of gloves, and thorough cleaning of workspaces. This ensures that medications remain safe and effective for patients. Each step in the preparation or dispensing process must be carefully monitored to avoid this risk.

The other options focus on different aspects of pharmacy practice. Preventing errors in medication labeling involves accuracy in drug dispensing but does not directly relate to the concept of cross-contamination. The duplication of patient medication records pertains to record-keeping rather than contamination issues, and mixing incompatible medications, while a serious concern, addresses a different matter concerning drug interactions rather than contamination during handling procedures.
