In the swine comprehensive integrated disease surveillance program, which diseases have been reported as free in commercial swine?

The correct answer emphasizes the significance of swine brucellosis and pseudorabies being categorized as diseases that have been reported as free in commercial swine. This reflects advancements in veterinary public health and biosecurity measures that allow swine populations, particularly those in commercial systems, to achieve disease-free status.

Swine brucellosis, caused by the bacterium Brucella suis, used to be a significant concern in swine health, but through effective vaccination programs and management practices, many commercial herds have successfully eradicated this disease. Similarly, pseudorabies, which is a viral infection caused by the Suid herpesvirus 1, was historically prevalent, but widespread vaccination and control measures have led to a significant reduction in its incidence, allowing for the declaration of disease-free status in many commercial operations.

This demonstrates ongoing efforts in swine herd health management that contribute to overall food safety and security, highlighting the successes within the agricultural sector in controlling these diseases. Understanding the importance of these disease-free achievements is crucial in the context of global health and food security, as it helps ensure healthy livestock production and reduces the risk of zoonotic diseases.
