Iowa confirmed highly pathogenic avian influenza (H5N1 HPAI) in a commercial pullet flock in Buena Vista County on March 14, 2025. It was Iowa’s sixth H5N1 detection in domestic birds that year and the county’s second reported detection in 2025. The official notice did not publish the pullet flock’s size; the more-than-26,000-bird figure associated with Buena Vista County belongs to an earlier commercial turkey flock, not this event.
What happened in Buena Vista County
The Iowa Department of Agriculture and Land Stewardship (IDALS) and USDA Animal and Plant Health Inspection Service (APHIS) announced the confirmed detection in a commercial flock of pullets on March 14, 2025. H5N1 HPAI is a viral disease that affects wild and domestic birds. Wild birds can carry the virus without visible illness, while infection is often fatal in domestic chickens and turkeys. The state’s announcement is available in the IDALS and USDA APHIS release.
A pullet is a young female chicken being raised for future egg production. Calling this a pullet-flock detection therefore identifies the birds as young egg-laying chickens, rather than laying hens already in production or meat birds.

| Date | Flock and location | Reported count | How it relates to the titled event |
|---|---|---|---|
| March 14, 2025 | Commercial pullet flock, Buena Vista County | Not stated in the official release | The confirmed H5N1 HPAI detection covered here |
| Earlier in 2025 | Commercial turkey flock, Buena Vista County | More than 26,000 birds, according to Iowa Capital Dispatch | A separate county detection; its count must not be assigned to the pullet flock |
| March 4, 2026 | Multi-species backyard flock, Buena Vista County | Approximately 35 birds | A later backyard event, not the 2025 commercial pullet case |
The official 2025 pullet notice does not provide the flock’s bird count. There is no sound basis for estimating it from the turkey or backyard figures.
Signs that can indicate H5N1 in poultry
Owners and caretakers should treat unusual illness or mortality as urgent. IDALS lists these possible signs:
- A sudden increase in deaths, sometimes without obvious clinical signs
- Lethargy, reduced energy or loss of appetite
- A drop in egg production
- Soft-shelled, thin-shelled or misshapen eggs
- Swelling of the head, eyelids, comb, wattles or hocks
- Purple or blue discoloration
- Breathing difficulty, coughing, sneezing or nasal discharge
- Stumbling, falling or other neurologic problems
- Diarrhea
These signs are not a diagnosis by themselves. A veterinarian or animal-health official must evaluate suspected cases.
What to do if birds may be infected
Contact a veterinarian immediately
Do not wait for additional deaths or attempt to move apparently healthy birds into another group. Call a veterinarian as soon as H5N1 is suspected so the flock can be assessed and the appropriate testing and control process can begin.

Are eggs and poultry safe to eat?
IDALS states that eggs and poultry products remain safe to enjoy when consumers handle and cook them properly. Its notice says: It remains safe to enjoy eggs and poultry products. As a reminder, consumers should always properly handle and cook eggs and poultry products, including cooking to an internal temperature of 165°F.

Use an instant-read food thermometer to check the thickest part of the food and follow ordinary precautions against cross-contamination, such as washing hands and cleaning surfaces after handling raw poultry or eggs. A cooking thermometer measures temperature; it does not detect H5N1 and does not provide medical protection.
The same Iowa notice says the Centers for Disease Control and Prevention (CDC) believes the threat to the general public remains low.
That assessment concerns the general public; people who work closely with infected or potentially infected birds should follow occupational and animal-health guidance.

How Iowa poultry operations can strengthen biosecurity
IDALS strongly encouraged Iowa poultry producers and dairy farmers to reinforce their biosecurity practices and protocols after the detection. For a commercial operation, a practical review should cover:
- Access control: know who enters poultry areas, restrict unnecessary visitors and keep a written visitor log.
- Dedicated clothing and footwear: use clean, site-specific clothing and footwear, and prevent contaminated boots or equipment from moving between flocks.
- Cleaning and disinfection: remove organic material before disinfecting vehicles, tools, crates and other equipment; follow the disinfectant label for concentration and contact time.
- Separation: keep domestic birds away from wild birds, standing water and feed or water sources that wild birds can reach.
- Daily monitoring: track deaths, feed and water intake, behavior and egg production so a change is recognized quickly.
- Response planning: make sure employees know whom to call, how to isolate a concern and how to avoid carrying contamination to another barn or premises.
Backyard owners should apply the same principles at a smaller scale: limit visitors, keep footwear and equipment dedicated to the flock, prevent contact with wild birds and report unexplained illness or deaths promptly.
What this detection does—and does not—establish
This case establishes a confirmed H5N1 HPAI detection in a commercial pullet flock in Buena Vista County on March 14, 2025. It does not establish the flock’s size, because that number was not published in the official release. It also does not make the earlier turkey count or the later backyard count applicable to the pullets.
Quick Recap
Key points for Iowa bird owners and consumers
- The affected birds were commercial pullets—young female chickens destined for egg production—not the separate turkey flock previously reported in the county.
- The event was Iowa’s sixth domestic-bird H5N1 detection in 2025 and Buena Vista County’s second reported detection that year.
- Watch for sudden deaths, appetite or egg-production declines, abnormal eggs, swelling, discoloration, respiratory or neurologic signs and diarrhea.
- Report suspected cases to a veterinarian and IDALS at (515) 281-5305.
- Consumers can continue eating eggs and poultry when they are handled properly and cooked to an internal temperature of 165°F.
