Protect your cattle farm against Salmonella
Researchers found Salmonella in approximately 10% of Dutch dairy farms, posing a significant risk to the industry. An outbreak can result in costs of €4.637 for a farm with 100 dairy cows, and without immediate action, these costs can escalate to €10.000.
Understanding the strains involved, transmission routes, and symptoms is key to effective management and prevention in your dairy herd.

What causes Salmonella in dairy cattle
Salmonella is a gram negative rod-shaped genus belonging to the Enterobacteriaceae family. There are more than 2700 types of Salmonella known. These are subdivided into groups, based on differences in antigens.
In dairy herds, Salmonella infections are primarily caused by two groups of strains:
1. Host-Adapted Strains:
- Salmonella Dublin: Specifically adapted to cattle, causes more severe symptoms and significant health issues in dairy cows. This strain has the potential to lead to chronic carriers.
2. Non-Host-Adapted Strains:
- Salmonella Typhimurium: A strain that can affect various animal species, including humans. It's a common cause of zoonotic infections, where the bacteria are transmitted from animals to people, often through contaminated food products.
- Other Strains: While less common, various other non-host-adapted Salmonella strains occasionally infect dairy cattle.
How does Salmonella spread?
Salmonella can reach cows through direct contact with infected cattle and indirect contact through:
- Manure
- Contaminated Feed and Water: The primary transmission route.
- Environmental Exposure: Contact with contaminated soil or bedding.
- Carrier Animals: Including wildlife, rodents
- Human Interaction: Via contaminated equipment, boots, or hands.
- Contaminated equipment, tools or clothes
- Contaminated vehicles (trucks, tractors, robots)

How can you protect your cows from Salmonella?
Good biosecurity is the most important defense that farmers have to prevent the introduction of Salmonella to their farms.
Maintaining and optimizing hygiene for the environment, visitors, vehicles, feed and all goods entering the farm are important to prevent the introduction of salmonella
Stay vigilant and proactive in safeguarding your dairy herd against Salmonella for a healthy and productive farm.
