La Yongjia Trade Co., a food importer in Vernon, California, failed to comply with Foreign Supplier Verification Program (FSVP) requirements for imported fresh enoki mushrooms. FDA inspection from February 15-23, 2023 found that the company imported mushrooms contaminated with Listeria monocytogenes from multiple foreign suppliers that had already been placed on Import Alerts for pathogenic contamination and insanitary preparation conditions. The company's suppliers were subject to Import Alert #99-23 (detention due to human pathogen contamination) and Import Alert #99-35 (detention due to insanitary conditions), yet the company continued importing from these sources without performing adequate risk-based verification activities to ensure compliance with U.S. food safety standards.
