FDA Food Facility Inspection - Preparing For, Hosting, and Following Up

FDA investigators inspect registered food facilities under Section 704 of the FD&C Act to assess compliance with requirements such as 21 CFR Part 117. The investigator issues a notice of inspection, tours the facility, reviews the food safety plan and records, and holds a closing meeting where any observations are listed on a Form FDA 483. The facility then responds, corrects, and waits for FDA to classify the inspection. This map follows the pathway from readiness through conduct, closeout, and response.

Form FDA 483

Form FDA 483

A list of inspectional observations given to management at the end of an inspection. It is not a final determination of a violation.

Basis: Closing meeting

Establishment Inspection Report

The investigator's written report. FDA considers it with the 483, the evidence, and the firm's response.

Basis: Basis for classification

Inspection Classification

FDA classifies the inspection as No Action Indicated, Voluntary Action Indicated, or Official Action Indicated.

Basis: NAI, VAI, or OAI

Records Access

Required records must be promptly available to an authorized representative on oral or written request.

Basis: 21 CFR 117.320
Phase 1
Inspection Readiness
1Maintain an inspection readiness program
A designated coordinator, a trained escort team, and a clear process for the first hour of any inspection.
Readiness practice
↓
2Keep records organized and retrievable
Records accurate, legible, created at the time of the activity, and retained at least 2 years at the facility.
21 CFR 117.305 · 117.315
↓
3Keep the food safety plan complete and signed
Plan with hazard analysis, controls, supply-chain program, and recall plan, signed and dated by the owner, operator, or agent.
21 CFR 117.126 · 117.310
↓
4Run mock inspections
Internal or third-party mock inspections that follow the investigator's path and test the team under pressure.
Readiness practice
Phase 2
Opening and Conduct
Can the requested record be produced now?
YES → Provide a copy and log it NO → Log it and state when it will be delivered
↓
5Receive the investigator and the notice
Credentials verified, the inspection coordinator notified, and the Notice of Inspection, Form FDA 482, received.
FD&C Act 704(a)
↓
6Hold the opening meeting and escort the tour
Scope and expectations clarified, and the investigator escorted at all times with questions answered accurately.
Readiness practice
↓
7Respond to document requests
Records requested are logged, reviewed, copied, and provided promptly, with offsite records retrievable within 24 hours.
21 CFR 117.320 · 117.315
Phase 3
Closeout
8Debrief daily and track observations
The team meets each day to review what was asked, what was seen, and what may be cited, and to start fixing what can be fixed.
Readiness practice
↓
9Attend the closing meeting
Each observation on the Form FDA 483 is read and discussed with management, and clarifying questions are asked.
FD&C Act 704
↓
10Correct and document on the spot where possible
Corrections made during the inspection are documented, and evidence of them is kept for the response.
Readiness practice
Phase 4
Response and Follow-Up
11Respond to the Form FDA 483 in writing
A written response with a corrective action plan, usually within 15 business days so FDA can consider it before classification.
FDA 483 process
↓
12Follow through and update FDA
Corrective actions completed on the dates promised, with evidence, and progress updates sent where actions take longer.
FDA 483 process
↓
13Review the outcome and reanalyze
Classification and any further FDA action reviewed, and the food safety plan reanalyzed for gaps the inspection exposed.
21 CFR 117.170
Inspection Classifications (Overview)

NAI - No Action Indicated

No objectionable conditions or practices were found, or those found do not justify further regulatory action.

FDA classification

VAI - Voluntary Action Indicated

Objectionable conditions were found, but FDA does not expect to take regulatory action, and the firm is expected to correct voluntarily.

FDA classification

OAI - Official Action Indicated

Significant objectionable conditions were found and regulatory or administrative action may be recommended, such as a Warning Letter.

FDA classification

Records Request Handling (Overview)

Log every request One person records what was asked, when, who handled it, and what was provided.
Review before releasing The coordinator checks that the record is the right one and complete, and provides copies.
Keep a duplicate set A copy of everything provided is kept so the facility knows exactly what FDA has seen.
Be accurate and prompt Records are provided promptly, and if something cannot be found, the facility says so and says when it will follow up.

Key Inspection Outputs (Overview)

Inspection log Requests, records provided, interviews, and areas visited, recorded as the inspection happens.
Copies of records provided A duplicate set matching what FDA received.
Form FDA 483 and written response The observations received and the facility's reply, with the corrective action plan.
Corrective action tracker Each commitment, owner, date, and evidence of completion, until closed.

Inspection Readiness Quality Elements

Designated Coordinator One person leads the inspection and owns the flow of information.
Trained Escorts People who know the facility and the process escort the investigator and know what to say and not say.
Organized Records Records stored so any required document can be found and produced quickly.
Consistent Messaging The team gives the same accurate answers, and no one speculates.
Honest Answers Questions are answered truthfully, and when unsure, staff say they will find out.
Daily Debrief Every day the team reviews what happened and prepares for the next.
Timely Response A written, complete response is submitted within the expected time.
Follow-Through Commitments in the response are completed on time, with evidence.

Never do this

Hide, alter, or destroy records. Guess at an answer. Leave the investigator unescorted. Argue about an observation instead of understanding it. Promise a corrective action you cannot deliver by the date you give.

Form 483 vs Warning Letter

A Form 483 lists observations at the end of an inspection and is not a final determination. A Warning Letter is a formal notice of significant violations that FDA may issue afterward, based on the inspection and the facility's response. Both need a prompt, credible written response.

How often FDA inspects

FSMA directs FDA to inspect high-risk domestic food facilities at least every 3 years and non-high-risk facilities at least every 5 years, in addition to for-cause inspections after outbreaks, recalls, or complaints. Be ready at all times, not only when a date is known.
