H5N1 risk to the public remains low as One Health focused disease response continues

One Health Logo

The Centers for Disease Control and Prevention (CDC) highlighted a recent report showing 7-percent of farm workers exposed to H5N1 during dairy cow outbreaks in Michigan and Colorado had evidence of recent infection. Several of those workers did not recall experiencing H5 symptoms. It's very important to note the risk to the general public remains low and remains an occupational risk to those in direct contact with infected animals. The goal of animal health officials responding to outbreaks in dairy is to keep that risk low by utilizing the One Health approach to disease, which takes into account people, animals and the environment.

The two most common ways people are becoming infected with H5N1 is direct exposure to sick birds during depopulation of infected farms and dairy workers exposed to sick cows during milking. This is where One Health efforts like biosecurity come into play to limit the spread of the virus to more animals. Additionally, Personal Protective Equipment (PPE) can help keep workers and responders safer. English and Spanish PPE recommendations and resources can be found online. One of the best proactive approaches farmers can take to stop the spread of H5N1 before it starts is to test sick animals. Learn how to test dairy cows for H5N1 in Minnesota.

New EID requirements in effect

On November 5, the new federal requirements for electronic identification like Radio Frequency Identification (RFID) tags went into effect. All official ID tags applied to cattle and bison must be visually and electronically readable. Any tags placed in an animal before November 5 are "grandfathered in" for the life of the animal and do not need to meet the requirements.

There are no free tags available to producers, veterinarians or markets via the Board of Animal Health at this time. Tags may be purchased from approved manufacturers, which can be found on our RFID Frequently Asked Questions document.

In Minnesota, the EID requirements apply to all interstate and intrastate movements. Not sure of the difference between those movement types? Have other questions? Register for a free RFID webinar for Minnesota cattle producers on November 26 at 1 p.m.

Tularemia cases trend high in 2024 and continue being reported

Minnesota has tallied 23 cases of tularemia in animals this year, which is unfortunately a new record. Tularemia case counts usually drop off in November so Board and MDH staff are hopeful cases will slow soon. Remember, the disease is reportable in Minnesota and veterinarians must report results to the Board at 651-296-2942 or companion.animal@state.mn.us.

Here's a summary of some of the most recent tularemia cases reported:

  • In early October a 9-month-old previously stray kitten from Apple Valley was found wandering outside and his new owners took him in. He appeared healthy until later in the month when his hind legs weakened, he became lethargic, and he stopped eating. He was brought into the veterinarian where he had a fever and other clinical signs. Imaging showed an enlarged kidney and irregular liver. The cat was treated with fluids and antibiotics.
  • At the end of October, a 4-year-old miniature schnauzer from Richfield was brought into the veterinarian for dew claw pain, which was found to be unrelated to tularemia. During the examination, the veterinarian noticed the lymph nodes were twice their normal size. On questioning, the owners reported the dog had exposure to a dead rabbit about a week prior. Other than the lymph nodes, it was asymptomatic. The dog was treated with antibiotics.
  • Recently, University of Minnesota Veterinary Diagnostic Laboratory necropsy staff found a dead wild rabbit near their office and collected swabs from the spleen, which turned out to be positive for tularemia..
  • A 7-month-old kitten from Northeast Minneapolis became lethargic and had decreased appetite in late October and was brought into a veterinary hospital. There, she had a fever, labored breathing, swollen lymph nodes and other clinical signs. She was started on antibiotics and made a full recovery.
