FDA cited this observation 576 times across 508 firms in recent inspections. Below: how it breaks down by program area and fiscal year, and real examples of how FDA worded it on Form FDA 483.
What this grouping is not
An observation-type page groups FDA’s published citation records. The grouping, the compliance steps and the root causes are SPEQ synthesis, not an FDA classification of any citation, and a count measures what FDA published rather than risk.
What this observation means, and how to comply
SPEQ's practitioner reading of this finding. The regulatory basis is a cited fact; the interpretation, compliance steps, and root causes are SPEQ synthesis — not an FDA classification of the citation.
The plant’s cleaning, sanitizing, and maintenance of equipment and utensils were inadequate to prevent contamination — either the activities were insufficient, or the maintenance of the cleaning state was not sustained.
Why FDA writes it — Cleaning and maintenance together keep equipment in a state that will not contaminate food. A one-time clean that is not maintained, or maintenance that neglects cleanability, both let contamination return — so FDA treats the combined cleaning-sanitizing-maintenance regime as a front-line control.
- Clean and sanitize equipment and utensils as necessary, and maintain them in a condition that prevents contamination.
- Keep cleaning compounds, sanitizers, and the tools used to apply them controlled and stored to avoid becoming a contamination source themselves.
- Follow documented cleaning and maintenance schedules and record their completion.
- Repair or replace equipment that can no longer be effectively cleaned.
- Cleaning treated as separate from maintenance, so a well-cleaned but deteriorating surface still contaminates.
- No documented schedule, so lapses accumulate unseen.

What this observation is associated with
Firms cited for this observation also appear in FDA compliance actions — warning letters, injunctions, or seizures — at 4.8× the rate of the average FDA-cited firm (36.8% vs 7.8%), across 508 FEI-matched firms.
This is an association, not causation, and reflects co-occurrence in FDA's records — not a claim that the observation caused or preceded the action.
