Stop A Salmonella Outbreak Before It Starts
With prevalence of Salmonella on the rise and a hot, humid summer, now is the time to help protect dairies from potential Salmonella outbreaks.1
“Salmonella bacteria are hard to keep off dairy operations, and if it enters a herd, it can be tough to recognize,” said Gary Neubauer, DVM, Zoetis. “Knowing the many access points to the dairy and implementing a Salmonella control program are important to help close doors to the disease.”
Four steps to improve biosecurity plans
Salmonella is an intestinal bacterium that can cause significant disease in dairy cattle. It typically is spread from the waste of one animal, and then ingested by another. A cow infected with subclinical Salmonella can be a carrier of the disease and appear healthy while shedding the bacteria to others. The disease can have devastating effects on a dairy, and there are limited prevention and treatment products to manage the disease. Here are four simple steps to help improve Salmonella control on your dairy.
Step 1: Stop the spread
Whenever cattle from another source enter the dairy, pathogens can tag along. Commingling and allowing nose-to-nose contact with heifers from other dairies can allow disease transmission. Bacteria could be living in the cattle or on the trailer or the truck transporting the cattle.
Establish testing and quarantine protocols before allowing cattle to commingle with your herd. Clean and disinfect trailers transporting cattle after every shipment. Work with the company transporting cattle to discuss their biosecurity measures.
Step 2: Keep rodents, wildlife, pets and other livestock away
Rodents and wildlife can drop by unexpectedly and can carry diseases such as Salmonella. Many operations have pets, such as cats or dogs, while others are home to other livestock.
Although it might be impossible to keep wildlife and pets off the property, take steps to keep animals away from cattle. “Wildlife and rodents often are looking for food,” Dr. Neubauer said. “Keep feed storage clean and protected to keep animals out of those areas.”
Step 3: Develop Biosecurity Plan for employees, consultants and visitors
People also can bring Salmonella and other diseases to a dairy. Every day, employees, veterinarians, nutritionists and visitors travel on and off operations, as well as to and from cattle pens. They could be bringing Salmonella with them.
“Visitors should not be allowed to enter or go near the feeding areas or pens unless they adhere to biosecurity measures, using footbaths and wearing protective clothing,” Dr. Neubauer said. Veterinarians and artificial insemination (AI) technicians also should wear clean coveralls and boots before entering cattle pens.
Step 4: Develop a prevention plan
“Evaluating risks and ensuring doors are not open for the disease to enter dairies are critical,” Dr. Neubauer explained. A good first step is to take a risk assessment, such as the short questionnaire found at SalmonellaRisk.com/Assessment.
After taking the assessment, your veterinarian can help develop a Salmonella prevention and biosecurity plan. Vaccination is a key component of any Salmonella control program. Vaccines, such as SALMONELLA NEWPORT BACTERIAL EXTRACT VACCINE* with SRP® technology, can help prevent a clinical outbreak of Salmonella Newport, as well as help limit economic damage due to subclinical disease.2 Take proper steps to help reduce your risk of a devastating Salmonella outbreak.
