What does GMP stand for?
Good Manufacturing Practices
Good Maintenance Practices
General Management Policies
Good Manufacturing Procedures
GMP stands for Good Manufacturing Practices, which are guidelines ensuring products are produced consistently and controlled for quality. It does not refer to policies, maintenance, or procedures alone.
What is the primary focus of Good Hygiene Practices (GHP)?
Maximizing production throughput
Enhancing marketing strategies
Improving financial performance
Maintaining facility hygiene and preventing contamination
GHP focuses on facility hygiene, cleaning, and sanitation to prevent contamination of products. Financial, throughput, and marketing objectives are outside its scope.
Which document is essential for product traceability in GMP?
Quality policy manual
Organizational chart
Equipment maintenance log
Batch production record
The batch production record documents every step of manufacturing for traceability and compliance. Other documents support quality systems but do not trace individual batches.
Which practice best helps prevent cross-contamination in a production area?
Cleaning randomly without a schedule
Using color-coded cleaning tools for different zones
Using the same cloth for all equipment
Rinsing with water only
Color-coded tools ensure cleaning equipment is used only in designated areas, preventing cross-contamination. Random schedules or water alone are insufficient.
What is the primary purpose of a Standard Operating Procedure (SOP) in GMP?
To forecast financial budgets
To provide step-by-step instructions for consistent processes
To outline marketing plans
To detail human resource policies
An SOP provides detailed, standardized instructions to ensure consistent and compliant execution of processes. It is not used for marketing or financial planning.
Which GHP protocol specifically addresses pest control in a food processing facility?
Using color-coded utensils
Conducting regular microbial testing
Installing HEPA air filters
Sealing entry points and installing traps
Sealing entry points and installing traps are direct pest control measures. Microbial testing and air filters address other contamination risks but not pests.
When a calibration of a critical weighing scale fails, what immediate corrective action should be taken?
Discard all future batches
Recalibrate the scale and investigate the failure cause
Replace the operator
Continue using until next scheduled calibration
Failed calibration requires immediate recalibration and root cause investigation to ensure measurements remain accurate. Discarding batches or blaming staff is not appropriate.
Which document must be validated to ensure the effectiveness of cleaning processes?
Marketing protocol
Cleaning SOP
Quality manual
Organizational chart
The cleaning SOP must be validated to confirm that cleaning procedures consistently remove contaminants. Other documents do not detail the cleaning steps themselves.
What is the primary purpose of reviewing batch production records before product release?
To schedule staff training
To verify compliance with specifications
To generate marketing data
To prepare shipping invoices
A batch record review confirms that all manufacturing steps met predefined specifications before release. It is not conducted for marketing or invoicing purposes.
What is the recommended sequence for cleaning areas to minimize contamination risk?
Wet to dry areas
Inside out
Dirty to clean areas
Clean to dirty areas
Cleaning from the cleanest areas to the dirtiest helps prevent spreading contaminants into cleaned zones. The other sequences can reintroduce contaminants.
Which technique provides a rapid indication of surface cleanliness by measuring ATP levels?
Plate count method
Membrane filtration
Gas chromatography
Swab sampling with ATP bioluminescence
ATP bioluminescence swab tests rapidly detect organic residue. Plate counts and filtration are slower, and chromatography is for chemical analysis.
If environmental monitoring shows microbial counts above the alert level, what is the next step?
Release the product
Conduct a root cause investigation
Update unrelated SOPs
Discontinue monitoring
Exceeding alert levels requires a root cause investigation and corrective measures before resuming routine operations. Releasing product or stopping monitoring is not acceptable.
According to GMP guidelines, how long should critical production records typically be retained?
One month
Indefinitely
At least the product shelf life plus one year
Until the next FDA audit
Records must be kept at least as long as the product's shelf life plus a specified period, commonly one year. Shorter or indefinite retention is non-compliant.
What is the primary objective of a change control system in GMP?
To authorize increased production volumes
To track employee attendance
To reduce energy consumption
To manage modifications without risking the validated state
Change control ensures that any modifications are assessed, approved, and do not compromise validated processes. It is not concerned with attendance or energy use.
Which workflow design best reduces the risk of cross-contamination in a manufacturing facility?
Random movement of materials
Unidirectional flow from raw to finished product
Shared entry and exit for all zones
Bidirectional flow between areas
Unidirectional flow prevents the back-flow of contaminants into raw material or clean areas. Bidirectional or shared traffic increases contamination risk.
During equipment qualification, which phase verifies consistent performance under routine operating conditions?
Performance Qualification (PQ)
Operational Qualification (OQ)
Installation Qualification (IQ)
Design Qualification (DQ)
Performance Qualification (PQ) confirms that equipment consistently performs as intended under normal production conditions. IQ and OQ address installation and operational parameters.
In a contamination event investigation, which tool helps systematically identify potential root causes?
SWOT analysis
Gantt chart
Flowchart
Fishbone (Ishikawa) diagram
A Fishbone diagram breaks down possible causes into categories for structured root cause analysis. SWOT and Gantt charts serve strategic planning and scheduling roles, respectively.
For environmental monitoring, what sampling plan uses defined areas around equipment for swab tests?
Grid sampling
Composite sampling
Random sampling
Zone sampling
Zone sampling divides surfaces into pre-defined zones to ensure consistent and representative swab collection. Grid and random sampling are less structured for routine monitoring.
After discovering repeated documentation errors, which corrective and preventive action is most appropriate?
Discard all existing records
Modify marketing materials
Increase production speed
Revise procedures and retrain staff on record-keeping
Addressing documentation errors requires updating procedures and training personnel to prevent recurrence. Speeding up production or discarding records does not solve root causes.
When applying Quality Risk Management, how are manufacturing areas classified based on contamination risk?
By shift schedule
By production volume
By operator skill level
By grade designation (e.g., ISO classes) according to activity
Areas are classified into grades (ISO or EU GMP) based on allowable contamination levels and process criticality. Volume, skill, or shift do not determine classification.
