Biosecurity remains fundamental to protecting animal health and public health

Following an investigation by the Michigan Department of Agriculture and Rural Development (MDARD), the Michigan State University Veterinary Diagnostic Laboratory has detected the presence of highly pathogenic avian influenza (HPAI) in a commercial poultry facility located in Ottawa County. This is the second detection of HPAI in an Ottawa County flock this month. Biosecurity measures continue to be critical to help ensure the health of Michigan´s domestic animals and the general public.

"Slowing the spread of HPAI to protect human health is a top priority at MDARD," said MDARD Director Tim Boring. "Implementing on-farm biosecurity and expanding the state´s HPAI surveillance efforts are key strategies to prevent opportunities for the virus to infect domestic animal species and potentially spread and become a more concerning human threat."

HPAI is a highly contagious virus that can be spread in various ways from flock to flock, including by wild birds, through contact with infected animals, by equipment, and on the clothing and shoes of caretakers. The affected premises is currently under quarantine, and the birds will be depopulated to prevent disease spread. These efforts also help to ensure the safety and integrity of the commercial food supply.

"Even though the weather is cold, HPAI continues to circulate in wild bird populations creating ideal conditions for the virus to thrive and spread," said State Veterinarian Dr. Nora Wineland, DVM, MS, DACVPM. "It´s critical to prevent disease introduction by taking biosecurity measures such as keeping domestic animals away from wild birds and cleaning and disinfecting equipment between uses."
