Why is an audit done in bioprocessing?

Correct answer: To check whether process and records follow standards

An audit in bioprocessing is a systematic and documented examination of procedures, records, equipment, and quality practices. Its governing concept is quality assurance: the organisation checks whether the actual process follows approved standards, operating procedures, safety requirements, and documentation rules. Auditors may compare batch records with specifications, verify calibration and cleaning logs, and identify deviations or weaknesses. The purpose is not merely to find fault; it is also to support corrective action, traceability, consistency, and continual improvement. Therefore, option A is correct because it directly describes checking processes and records against standards. Hiding a product, changing culture medium into soil, or burning a fermenter has no legitimate connection with auditing.
