What must practitioners have in order to vaccinate calves for Brucella?

To vaccinate calves for Brucella, practitioners are required to have a contract with the California Department of Food and Agriculture (CDFA) if they are acting in that specific jurisdiction. This requirement ensures that the vaccination is performed in accordance with state regulations designed to control and prevent Brucellosis, a contagious disease that affects livestock as well as humans.

A contract with the CDFA typically includes guidelines on the timing, technique, and documentation necessary for the vaccination process. This regulation is crucial for maintaining herd health, protecting public health, and ensuring that the vaccination efforts are coordinated with state-level animal health programs.

While other options like having a special permit from the USDA or certification from a veterinary school may be relevant in different contexts of animal health, the specific aspect of vaccinating calves for Brucella hinges on the relationship and regulatory requirements set forth by the CDFA. Approval from local animal health authorities may also be necessary, but here the focus on the contract explicitly ties back to the state’s operational framework and oversight.
