FDA 483 OBSERVATION · #91 OF 1,923 MOST-CITED

Prevention of contamination

FDA cited this observation 310 times across 251 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.

21 CFR 117.80(c)

Manufacturing, processing, packing, and holding operations were not conducted with adequate controls to prevent food from becoming contaminated. This is the broad processes-and-controls requirement covering cross-contamination, foreign material, and microbial ingress during actual operations.

Why FDA writes it — Contamination introduced during processing reaches product that ships to consumers; FDA cites this when the operation lacks the routine physical, chemical, and microbial safeguards — segregation, protection, and handling controls — that keep raw materials, in-process food, and finished product safe.

HOW TO COMPLY
  • Define and follow written controls that segregate raw from finished product and prevent cross-contact during handling.
  • Protect food, containers, and food-contact surfaces from contamination by drips, condensate, foreign material, and personnel.
  • Control the parameters (time, temperature, pH, water activity) that keep microbial growth and contamination in check during operations.
  • Monitor these controls, record the results, and take corrective action when a control is not met.
WHY FIRMS GET CITED
  • Processing controls exist on paper but are not embedded in line practice, so operators improvise when conditions change.
  • The operation was scaled up or a new product added without reassessing where contamination could enter the process.

What this observation is associated with

Firms cited for this observation also appear in FDA compliance actions — warning letters, injunctions, or seizures — at 0.2× the rate of the average FDA-cited firm (1.6% vs 7.8%), across 251 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.
