Sign in to monitor this recall

Summary

Fort Dodge Laboratories Inc. is recalling approximately 70,094 units of Synovex Plus (trenbolone acetate and estradiol benzoate) implants, which are growth promoters for steers and heifers. The recall was initiated because the packaging seals may have failed, potentially compromising the sterility or stability of the medication. These products were distributed to veterinary clinics and distributors nationwide and internationally in countries including Canada and Mexico.

Risk

A failure in the package integrity can lead to contamination of the implants or a loss of drug potency. Using compromised implants on livestock may result in ineffective treatment or localized infections at the site of implantation.

  3. Immediately stop using any implants from these affected cartridges and foil pouches.
