The affected lots were distributed to wholesalers and hospitals between December 30, 2024, and May 5, 2026. Par Health stated that administration of affected product could cause life-threatening vascular and inflammatory consequences. No related adverse events had been reported. Wholesalers and hospital pharmacies were instructed to discontinue use and distribution immediately and return existing inventory.

FDA Warning Letter: Hanlim Pharm cited for sterile manufacturing and quality system deficiencies

by

FDA cited significant CGMP violations following an April 2026 inspection of Hanlim Pharm’s drug manufacturing facility. Inspectors observed poor aseptic practices, including operators obstructing first air, working directly over exposed components, and wearing a visibly stained gown. Dynamic smoke studies did not demonstrate adequate unidirectional airflow protection and indicated possible entrainment of lower-quality air into the ISO 5 processing line. FDA also found that critical container-closure contact surfaces were wiped with sporicidal disinfectants rather than sterilized. Environmental monitoring locations and frequencies were not adequately justified or sufficient to detect contamination risks near containers, closures, and barriers facing ISO 5 areas. The visual inspection program lacked routine defect categorization and appropriate acceptance criteria despite significant defect rates. FDA further stated that the quality unit lacked adequate authority and oversight, citing failures involving the stability program and contemporaneous documentation of environmental and personnel monitoring data. FDA considered the company’s responses inadequate and noted similar violations in a previous warning letter.

FDA Warning Letter: Sterility, Component Testing, and Quality Unit Deficiencies at Jiangmen Shuizirun

by

FDA states that its November 3–7, 2025, inspection of Jiangmen Shuizirun Sanitary Articles found significant CGMP violations in OTC drug manufacturing. Several products were labeled “sterile,” although they were not sterilized, the certificates of analysis did not claim sterility, and the firm did not perform release sterility testing. One released batch had a reported aerobic microbial count, which FDA said was unacceptable for a sterile-labeled drug. FDA also found inadequate identity and impurity testing for incoming components and purchased in-process materials, including high-risk ingredients, while supplier certificates were relied upon without establishing their reliability. The quality unit did not adequately oversee documentation, written production procedures, process and system validation, stability testing, or finished-product testing. FDA additionally noted that the same batch number was assigned to different products, and that neither the firm nor its U.S. Agent responded to FDA’s attempts to discuss recalling sterile-labeled products in U.S. distribution.

FDA cites CGMP violations at Jiangmen Shuizirun OTC drug facility

by

FDA issued a warning letter to Jiangmen Shuizirun Sanitary Articles Co., Ltd. after a November 2025 inspection of its Chinese OTC drug manufacturing facility identified significant CGMP violations. FDA stated that products labeled “sterile” were not sterilized, lacked release sterility testing, and were assessed against microbial limits unacceptable for sterile drugs. The agency also cited inadequate identity and impurity testing of incoming components, reliance on supplier certificates without establishing reliability, and deficient quality-unit oversight of documentation, process validation, procedures, stability, and finished-product testing. FDA additionally identified non-unique batch numbering, recommended removal of within-expiry sterile-labeled products from the U.S. market, and noted that the firm’s drugs were placed on Import Alert 66-40.

FDA Warning Letter: SCA Pharmaceuticals cited for aseptic processing and contamination-control deficiencies

by

FDA states that its October 20–30, 2025, inspection of SCA Pharmaceuticals’ Little Rock outsourcing facility found serious deficiencies in production of drugs intended or expected to be sterile. Investigators cited inadequate certification and dynamic airflow visualization of ISO 5 areas, airflow and HEPA-supplied positive-pressure concerns, poor aseptic practices, deficient material disinfection, and environmental monitoring that was not representative of production conditions. FDA also found inadequate evaluation of microbial contamination in ISO 5 areas and insufficient investigations, CAPA, and batch-impact assessments. Component and visual inspection controls did not adequately identify, classify, investigate, trend, or address particles and foreign material between syringe stopper ribs. Laboratory controls and Quality Unit procedures were cited as inadequate. Production videos used in investigations were overwritten after approximately a redacted period, with only still images retained. FDA found some responses deficient and could not fully evaluate others because supporting documentation was inadequate, and recommended a comprehensive aseptic operations assessment assisted by a qualified sterile-manufacturing consultant.

FDA Warning Letter: Microbiological Data and Quality Unit Deficiencies at Eurofins SF Analytical Laboratories

by

FDA states that its June 1–3, 2026 inspection of Eurofins SF Analytical Laboratories’ contract testing facility identified significant finished-drug CGMP violations in microbiological testing and quality oversight. Analysts did not record certain results assessed as too numerous to count and selectively documented results, while cracked and desiccated plates were reported as within limits or as 0 CFU. FDA also observed a colony on a plate recorded as 0 CFU. The procedure did not require secondary verification of initial zero counts, and compromised plates were discarded without secondary review. FDA found that aberrant media conditions were not thoroughly investigated; the firm’s retrospective conclusions relied on interviews and records it acknowledged were unreliable, without photographic evidence of plate conditions. FDA considered the response inadequate because it did not assess effects on certificates of analysis or customers, verify historical data completeness, or commit to discontinuing damaged plates. FDA further stated that the quality unit lacked adequate authority, oversight, and control over laboratory operations and requested independent assessments, CAPA, stronger investigation systems, sample custody controls, photographic documentation, and quality-unit remediation.

FDA Warning Letter: Microbiological OOS Investigations and Quality Unit Oversight at Silgan

by

FDA inspected Silgan Unicep Packaging’s Spokane, Washington, drug manufacturing facility from March 26 to April 2, 2026, and reported significant CGMP violations involving non-sterile OTC products. FDA found that the firm inadequately investigated OOS microbiological results for components. Individual yeast and mold failures were invalidated by averaging sample results to obtain passing outcomes, and the sampling plan was revised to permit averaging, which FDA said was inconsistent with USP and could obscure non-uniform contamination. Affected component lots were released and used in distributed product. FDA also found the investigation associated with a Class I recall for potential fungal contamination inadequate: a bioburden-reduction corrective action was ineffective, related change control lacked appropriate validation and evaluation, the manufacturing line lacked cleaning procedures and cleaning validation, and environmental monitoring omitted yeast and mold testing. Separately, FDA said the quality unit failed to ensure supplier test reliability, follow the written stability program, and complete annual product reviews. FDA deemed the responses inadequate because they lacked sufficient scope, supporting evidence, effectiveness verification, product-risk measures, and remediation of systemic quality oversight failures.

Par Health Recalls Two Brevital Sodium Lots for Cellulose Particulate Matter
