North Dakota has confirmed its first anthrax case of 2025 in a beef cattle herd in Stark County. The confirmation came from the North Dakota State University Veterinary Diagnostic Lab. State officials say this case is an important reminder for livestock producers to protect their herds against the disease, especially in regions where anthrax has appeared before.
Dr. Ethan Andress, the state veterinarian, explains that producers in affected counties should speak with their veterinarians about vaccination needs and risk factors. He adds, “If producers have unusual losses on pasture, they should reach out to their local veterinarian as they are experienced and trained for this type of response.” The state veterinarian’s office is working with local resources to assist farmers in managing the situation.
Effective vaccines are available for anthrax, but they take more than a week to provide immunity. Annual booster shots are also required to maintain protection. Farmers are encouraged to monitor their animals closely and send samples to diagnostic labs if unexpected deaths occur, as this gives the best chance for accurate testing.
According to Agriculture Commissioner Doug Goehring, anthrax has been found in nearly every part of North Dakota. While some years bring only a few cases, other years see widespread losses. In 2024, just one case was reported in Adams County, but 2023 saw 25 cases in multiple counties. The most severe outbreak was in 2005, when more than 500 confirmed deaths were reported, with total livestock losses exceeding 1,000 animals.
Anthrax is caused by Bacillus anthracis, a bacteria that produces spores. These spores can survive in soil for decades and reactivate under certain conditions such as heavy rainfall, drought, or flooding. Animals are exposed when they graze on contaminated grass or drink tainted water.
