To put this record in context, PlainRecalls indexes 83,949 recalls across the FDA, CPSC, NHTSA and USDA FSIS going back to 1995. Within the same product category, the database holds 6 closely related recalls, of which 6 were also issued by CPSC. That clustering is a signal — repeated actions in a narrow category often indicate a systemic quality-control issue, a supplier-wide contamination, or a design defect that has propagated across product lines.
