Is bovine nodular disease contagious?

Nodule in cattle is generally contagious.

Bovine nodules are a common benign tumor, usually appearing in mammary tissue. The primary cause is hyperplasia of breast tissue, leading to blocked milk ducts and the formation of cysts or nodules. Other possible causes include hormonal changes, genetic factors, and dietary habits. Bovine nodules are a chronic infectious disease caused by Mycobacterium tuberculosis and can be transmitted through direct contact with infected animals or by consuming contaminated animal products. Therefore, bovine nodules are considered an infectious disease. Treatment methods depend on the size, number, and location of the nodules. Small nodules typically do not require treatment but should be monitored regularly. Large nodules or those suspected of being malignant may require biopsy or surgical removal. Additionally, certain medications may be used to alleviate symptoms or control nodule growth.

To prevent the spread of bovine nodules, a series of measures should be implemented, such as strengthening animal quarantine and isolation procedures, and enhancing testing and supervision of animal products. Meanwhile, individuals should also pay attention to food safety and avoid consuming untested animal products to prevent infections such as bovine nodules.
