Sign in to monitor this recall

Summary

Norbrook Inc. is recalling approximately 126,834 vials of veterinary injectable medications, including Enroflox 100 (enrofloxacin), Ivermax (ivermectin), and Noromectin (ivermectin), due to a lack of sterility assurance. These sterile solutions are used to treat infections and parasites in livestock. The company initiated the voluntary recall after discovering issues that could compromise the sterile nature of the products, which were distributed across several states and Puerto Rico.

Risk

Administering a non-sterile injectable medication can cause serious health complications for animals, including localized infections at the injection site, systemic infections, or abscesses. If the medication contains unintended microorganisms, it can lead to severe illness or death in treated livestock.
