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 is associated with
Firms cited for this observation also appear in FDA compliance actions — warning letters, injunctions, or seizures — at 2.7× the rate of the average FDA-cited firm (20.8% vs 7.8%), across 48 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.
