Mysterious illness sparks alarm among Swiss dairy cows

Swiss authorities are investigating a mysterious illness affecting dairy cows across the country. Livestock farms have reported a growing number of animals showing symptoms such as fever and diarrhea, often accompanied by a significant drop in milk yield. The Federal Food Safety and Veterinary Office (OSAV) confirmed it is aware of the increasing number of reported cases.

The cause of the illness that is leading to the cases has not yet been determined.

So far, the cause of the illness remains undetermined. Officials have launched an investigation to ascertain whether the condition stems from a metabolic issue or an infectious agent. Despite extensive testing, no responsible pathogen has been identified. OSAV also noted that there is no direct evidence linking the diarrhea cases to the recent hot weather, although high temperatures can negatively impact dairy cows, making them more vulnerable to diseases.

There is no evidence of a direct link between hot weather and diarrhea cases.

Switzerland, like other European nations, has experienced severe heatwaves and a significant decrease in rainfall in recent weeks. OSAV reminded farmers to protect their animals from high temperatures by ensuring access to sufficient water and providing shaded areas. The office also cautioned that symptoms like fever, diarrhea, and reduced milk production could be linked to highly contagious animal diseases, urging farmers to contact veterinarians immediately if they observe such signs. Further tests on affected herds are deemed necessary to pinpoint the source of the illness.
