One Health in Europe Lessons from Zoonotic Disease Control in Germany and the Netherlands

A virus in a wild bird, a bacterium in a dairy goat, or drug-resistant Salmonella in a food chain can become a public health problem long before a hospital sees the first patient. That is the core lesson behind One Health: human health, animal health, food systems, and the environment are connected.

Europe has learned this through hard experience. Zoonotic diseases, which pass between animals and people, do not respect national borders or professional boundaries. A farm outbreak can affect clinics, laboratories, food inspectors, wildlife services, and trade authorities at the same time. No single sector can manage that alone.

Zoonotic disease control often begins where people, animals, and food systems meet.

Why One Health matters for zoonotic disease control

One Health is not a slogan. It is a working method. It asks doctors, veterinarians, epidemiologists, food safety teams, wildlife experts, and environmental scientists to share information early enough to prevent harm.

That sounds simple, but it is difficult in practice. Each sector collects different data. Human health systems track patients, symptoms, tests, admissions, and deaths. Veterinary authorities track animal disease, farm movements, vaccination, culling, and surveillance. Food safety bodies inspect processing plants, trace products, and test samples. Environmental teams may monitor wildlife, water, insects, and habitat changes.

When these systems stay separate, outbreaks become harder to read. A cluster of pneumonia cases may not make sense until someone links it to infected goats nearby. A rise in resistant infections may need data from hospitals, farms, slaughterhouses, and antimicrobial sales. A bird flu event may require surveillance in wild birds and careful protection of poultry workers.

The value of One Health is speed with context. Faster reporting matters, but shared interpretation matters more. The right question is not only “What pathogen is causing illness?” It is also “Where is it moving, which species are involved, and which control point can break the chain?”

Europe’s approach has become more joined up because many of its risks are shared. Food moves across borders. Migratory birds follow flyways. Livestock trade connects regions. People travel daily for work and holidays. A local outbreak can quickly become a regional concern.

How EU initiatives connect human and animal health

The European Union has built a broad system for zoonotic disease control. It does not replace national authorities, but it gives them a common frame for surveillance, risk assessment, reporting, and response.

Several institutions matter.

The European Centre for Disease Prevention and Control focuses on human infectious disease threats. It supports surveillance, risk assessment, and outbreak response across EU and European Economic Area countries.

The European Food Safety Authority works on food and feed safety, animal health and welfare, and scientific risk assessment. It plays a central role in analysing zoonoses linked to the food chain.

The European Medicines Agency contributes to work on antimicrobial resistance through medicines regulation and monitoring of antimicrobial use in animals and people.

National public health institutes, veterinary services, food safety authorities, and laboratories feed data into shared systems. This allows Europe to compare patterns across countries instead of treating each outbreak as an isolated event.

The EU also supports common rules and reporting duties. Zoonoses monitoring, animal health legislation, food hygiene rules, and disease notification systems help countries speak the same technical language. When countries classify and report risks in similar ways, scientists can compare data and policymakers can act with more confidence.

Three areas show how this integration works.

Surveillance across the food chain

Routine monitoring of Salmonella, Campylobacter, Listeria, and other foodborne hazards links farms, slaughterhouses, food processors, retailers, and clinical laboratories. This makes it easier to identify whether human illness may be connected to animal reservoirs or food products.

Antimicrobial resistance monitoring

Drug-resistant bacteria can emerge in hospitals, communities, farms, and the environment. EU-level monitoring encourages countries to look across these settings. This supports more careful antimicrobial use in both human and veterinary medicine.
