Tuberculosis in cattle, camelids and farmed deer

The Norwegian cattle population has, apart from two single herd outbreaks in Sogn and Fjordane county in 1984 and 1986, been considered to be free of bovine tuberculosis since 1963. The disease has never been detected in camelids and in farmed deer in Norway.

The purpose of the surveillance and control program is to document freedom from tuberculosis in cattle (caused by Mycobacterium bovis), and to monitor the situation in camelids (llama and alpaca) and in farmed deer.

Tuberculosis caused by Mycobacterium tuberculosis (common in humans) is seldom detected in animals in Norway, most recently in a dog in 1989.

2025

In 2025, no infection with Mycobacterium tuberculosis complex was detected in catle, camelids or cervids. Results from passive surveillance, risk-based active surveillance in catle, and the investigation of one suspected case in catle, were consistent with the continued absence of bovine tuberculosis in Norway.
