In a test and remove strategy, what happens to a test-positive animal?

• A. Quarantined only
• B. Removed from the herd
• C. Treated and kept
• D. Causes whole herd condemnation

Answer: (B)

Test and remove aims to quickly identify infected animals and separate them from the herd to stop further spread. When an animal tests positive, the standard action is to remove it from the herd (often by culling or moving to a separate facility) to eliminate the source of infection. Quarantining alone doesn’t remove the infectious animal from contact with others; treating and keeping a positive animal risks continuing transmission; condemning the entire herd is not a required outcome of this strategy. Therefore, removing the animal from the herd is the appropriate step.
