Where should samples be sent for testing when vesicular disease is suspected in a herd?

• A. Plum Island
• B. Local diagnostic laboratory
• C. Abattoir
• D. CDC

Answer: (B)

When vesicular disease is suspected in a herd, the first step is to send samples to a local veterinary diagnostic laboratory. This lab acts as the frontline for rapid initial testing, proper sample handling, and appropriate biosafety measures. It can perform or arrange essential tests (such as molecular tests and virus detection) to screen for vesicular pathogens and determine the need for further confirmation. The local lab also coordinates with state veterinary authorities and, if needed, forwards specimens to national reference laboratories for definitive confirmation and regulatory reporting. Plumb Island is a specialized research facility not used for routine submissions, an abattoir is not a diagnostic testing center, and the CDC primarily handles human health—so they aren’t the appropriate first stop for animal vesicular disease testing.
