FDA Warning Letter: Fresenius cited for leaking dialysis solution bags and inadequate visual inspection controls
FDA inspected Fresenius USA Manufacturing’s Ogden, Utah drug facility from March 2-6, 2026, and cited significant CGMP violations involving complaint investigations, CAPA, process controls, and visual inspection of sterile injectable products. For Delflex Peritoneal Dialysis Solution, an August 2025 investigation covered 35 complaints involving approximately 156 leaking bags from multiple batches and attributed holes to printing. FDA stated that the firm assigned the lowest severity despite its matrix identifying peritonitis as a potential harm at the highest severity, did not recall then, and inadequately investigated risk and implemented CAPA. After inspection, reexamination found perforations without substantial fluid in the overwrap; the firm reassessed risk and recalled affected lots on April 6, 2026 for lack of assurance of sterility. FDA found the response still lacked sufficient CAPA to improve leak detection. FDA also found personnel qualification for visual particulate inspection inadequate because the kit was not adequately representative and records lacked sufficient detail, and said the response did not demonstrate reliable detection at an appropriate level.
