Food Manufacturing Metal Detector Verification Checklist [FREE PDF]

Metal detector verification is a critical control point (CCP) under HACCP principles and FDA FSMA 21 CFR 117 Subpart C, requiring documented testing at defined frequencies to prevent physical hazards from reaching consumers. SQF Code Edition 9 Section 11.7 and BRC Global Standard Issue 9 Clause 6.1 mandate that all detection equipment be calibrated, challenged with test pieces, and records maintained for audit traceability. Failure to verify metal detector performance can result in recall events

Industry: Food Manufacturing
Frequency: Daily
Estimated Time: 20-35 minutes
Role: QA Manager
Total Items: 35
Compliance: FDA FSMA 21 CFR 117 Subpart C - Hazard Analysis and Risk-Based Preventive Controls, HACCP Codex Alimentarius CAC/RCP 1-1969 Rev. 4-2003 - CCP Decision Tree, SQF Code Edition 9 Section 11.7 - Metal Detection and Foreign Body Detection, BRC Global Standard for Food Safety Issue 9 Clause 6.1 - Control of Foreign Body Contamination, GMP 21 CFR 110.80 - Processes and Controls

Equipment Identification and Pre-Use Inspection

Confirm the metal detector unit identity, condition, and readiness before production begins.

Is the metal detector unit ID and serial number recorded and matching the production line assignment?
Is the metal detector free from visible physical damage, corrosion, or unauthorized modifications?
Is the detector aperture clean and free from product buildup or debris that could affect sensitivity?
Is the reject mechanism (e.g., pusher arm, diverter gate, stop belt) operational and correctly positioned?
Has the previous shift's metal detector log been reviewed and any open deviations addressed?

Sensitivity Settings Verification

Verify that the metal detector is configured to the validated sensitivity levels for the current product.

Is the product program (sensitivity profile) set to the correct validated setting for the current run?
Is the ferrous test piece sensitivity setting at or below the validated detection threshold (record sphere diameter in mm)?
Is the non-ferrous (aluminum) test piece sensitivity setting at or below the validated detection threshold (record sphere diameter in mm)?
Is the stainless steel (SS316) test piece sensitivity setting at or below the validated detection threshold (record sphere diameter in mm)?
Are sensitivity settings password-protected or access-restricted to authorized personnel only?

Test Piece Challenge Testing

Conduct formal challenge tests using calibrated test pieces at the start of production and at defined intervals.

Was the ferrous test piece challenge completed and did the detector successfully reject the test sample?
Was the non-ferrous (aluminum) test piece challenge completed and did the detector successfully reject the test sample?
Was the stainless steel (SS316) test piece challenge completed and did the detector successfully reject the test sample?
Were test pieces passed through in product-representative packaging/containers to simulate real product conditions?
Was the reject mechanism verified to physically remove the test piece from the production flow during each challenge?
Were all test pieces accounted for and returned to secure storage after challenge testing?

Reject System and Quarantine Verification

Confirm the reject bin, lock, and quarantine procedures are functioning and properly managed.

Is the reject bin locked or secured to prevent unauthorized removal of rejected product?
Is the reject bin labeled with the current date, product lot, and rejection reason?
Is the rejected product quantity from the last shift recorded and disposition (rework/destroy) documented?
Is the stop-on-reject (fail-safe) or alarm feature active to halt production if the reject mechanism fails?
Was the reject alarm audibly or visually tested and confirmed functional at the start of this shift?

Calibration and Preventive Maintenance Status

Review calibration currency and scheduled maintenance compliance for the metal detection unit.

Is the metal detector within its current calibration period as defined by the calibration schedule?
Is the calibration certificate available and traceable to a NIST-accredited or equivalent standard?
Are all scheduled preventive maintenance tasks for this unit current and documented?
Have any maintenance or repair activities since the last inspection been recorded in the equipment log?
Are test pieces calibrated and within their certified accuracy date?

Deviation and Corrective Action Review

Assess response procedures when metal detector failures or false positives occur.

If a challenge test failed, was production immediately halted and product placed on hold?
If a failure occurred, was a root cause analysis initiated and documented within the required timeframe?
Was the QA Manager or FSQA Director notified of any critical deviation during this inspection period?
Were any false reject incidents recorded and investigated to prevent unnecessary product loss?
Are corrective action records for this unit retained for the minimum regulatory retention period (e.g., 2 years)?

Documentation and Inspector Sign-Off

Complete all required record entries and obtain authorized sign-off for this verification event.

Has all challenge test data (pass/fail, test piece size, time of test) been recorded in the CCP monitoring log?
Are any observations, anomalies, or near-misses documented in the comments section?
Has the completed checklist been reviewed and signed by the QA Manager or designee?
Has this record been filed or uploaded to the electronic QMS system within the required timeframe?
