Neogen Recalls HYCOAT Vials for Dogs, Cats and Horses Nationwide Over Contamination

Neogen Corporation (NASDAQ: NEOG) has announced a voluntary nationwide recall of all lots within expiry of Neogen®Vet HYCOAT® Hyaluronate Sodium Sterile Solution after detecting microbial contamination in certain 10 mL/50 mg vials. The recall is being conducted to the veterinarian level and affects product distributed to animal health distributors and veterinary practices nationwide.

The company says it received a number of reports of adverse events in horses that followed intraarticular injections of HYCOAT, a use the company described as inconsistent with the product’s labeled, intended use. Neogen noted that, to date, it has not received reports of adverse events when the product was used in a manner consistent with the label. Neogen also confirmed that it distributes the product while a third‑party supplier manufactures it; the supplier’s name was not provided.

Neogen stated that it is notifying distributors and direct customers by email and coordinating returns. “Neogen is notifying its distributors and direct customers by email and is arranging for return of all recalled products,” the company said, and advised that “Anyone that has HYCOAT which is being recalled should discontinue use and quarantine product.” Customers with questions can contact Neogen Animal Safety Customer Support Monday through Friday, 8AM-5PM EDT at 859-254-1221 or by email at AnimalHealth@neogen.com. Customers may also work through their distributor for product returns.

Veterinarians who experienced problems that may be related to the product were directed to report incidents to the FDA’s Center for Veterinary Medicine using FORM FDA 1932a, “Veterinary Adverse Experience, Lack of Effectiveness or Product Defect Report.” Neogen said no other Neogen products are affected by the recall, and that the action is being conducted with the knowledge of the U.S. Food and Drug Administration.

Key specifics remain unknown from the company announcement. Neogen did not list impacted lot numbers, name the third‑party manufacturer, identify the microbial organism, or provide counts or clinical details of the reported adverse events in horses. Those gaps matter for veterinarians and clinics trying to identify potentially exposed patients and for practices tracking inventory and clinical follow up.

Practical steps for clinics and pet owners are clear. Check clinic inventories and quarantine any HYCOAT 10 mL/50 mg vials immediately. Follow your distributor’s return instructions or contact Neogen Animal Safety Customer Support for return shipping directions. If you treated a dog, cat, or horse with HYCOAT and you observed an unexpected reaction, file FORM FDA 1932a and notify your distributor or Neogen as instructed.

This recall touches joint-care routines for active dogs and equine athletes and underscores the need to reconcile treatment records with clinic stock. Expect Neogen and regulators to release follow-up details such as lot codes and microbial findings; until then, prioritize quarantine and reporting so affected patients and practices can be identified and managed.
