What identifier is included in the Brucella tattoo?

The Brucella tattoo is utilized as a means of identifying animals that have been vaccinated against Brucella abortus, which is crucial for controlling brucellosis in livestock. The correct format for the tattoo includes the identifier "R-V-#", where "R" stands for "Revaccination," "V" indicates vaccination, and the "#" represents a unique number assigned to the individual animal.

This structure effectively communicates the vaccination status of the animal to veterinarians, animal health officials, and regulators without the need for additional records. It ensures clarity and consistency within animal health management practices. The other arrangements do not align with the standard identification format used for Brucella tattoos, which is why they are not considered correct.
