Paratuberculosis in livestock farming: understanding the risks and acting early
This document compiles recent scientific data on the prevalence of paratuberculosis in France and Europe, the health and economic impacts on cattle, goat, and sheep farms, as well as the currently recommended prophylactic measures.

Paratuberculosis: an underestimated disease in livestock farming
Paratuberculosis is a chronic infectious disease affecting cattle, sheep, and goats.
It is responsible for significant and often silent economic losses over several years and currently represents a major animal health and economic challenge for ruminant livestock farming.
In infected animals, the first clinical signs appear late, while bacterial shedding and herd contamination may have been ongoing for several years. This slow progression complicates early detection and facilitates the spread of the disease within herds.
Melchior Santé Animale provides a technical leaflet on paratuberculosis to help veterinarians and farmers better understand:
- Clinical signs in cattle, sheep, and goats;
- The economic impact of the disease;
- Available diagnostic methods;
- Prevention strategies (biosecurity and medical);
- Regulatory conditions related to vaccination.
Why act early against paratuberculosis?
Paratuberculosis is often described as an “iceberg disease”: for one animal showing visible clinical signs, several other animals in the herd may already be infected without showing any apparent symptoms.
The consequences in livestock farming may include:
- Decreased milk production;
- Reduced reproductive performance;
- Progressive weight loss in animals;
- Increased mortality;
- Long-term financial losses;
- Persistent environmental contamination.
An effective strategy is based on a comprehensive approach combining:
- Biosecurity;
- Management of young animals;
- Environmental control;
- Regular testing;
- Vaccination, where permitted by regulations.
