Methodology
Recall counts reflect FDA recall records explicitly referencing each K-number; FDA links recalls to K-numbers inconsistently, so 0 means "none found in FDA records," not "never recalled." Data: FDA openFDA, refreshed weekly. Verify decisions of consequence against the primary source. Full candidate set and CSV export: atlasbyauro.com.
