As fall settles in across the Midwest, the return of migratory birds is once again raising concerns about Highly Pathogenic Avian Influenza (HPAI), or H5N1. Neighboring states have already confirmed new cases of the virus, a reminder that the threat remains present for poultry producers and backyard flocks alike. With cooler weather drawing in more birds, Iowa farmers and bird owners are being urged to stay vigilant and prepared as the season progresses.
Iowa Agriculture Secretary Mike Naig says the seasonal shift is always a critical time to keep watch, as the risk for HPAI tends to climb during the spring and fall migrations. He notes that neighboring states like Nebraska and the Dakotas have already reported recent cases, including detections in poultry and even dairy herds. While most of the activity remains west of Iowa, Naig emphasizes that it is far from a hypothetical concern and serves as a clear reminder for producers to tighten biosecurity and prepare as if the virus will arrive.
Naig adds that Iowa’s experience during the devastating 2015 outbreak reshaped the way both state and federal partners respond to avian influenza. He says that episode exposed serious lapses in farm-to-farm biosecurity, but it also led to significant changes in prevention and response. Today, while the virus still makes its way into flocks through wild bird introductions, the industry has shown it can prevent the widespread lateral spread seen a decade ago. Even so, Naig stresses the need for constant vigilance, adaptation, and proactive measures to keep the threat in check.
As fall migration continues, Iowa agriculture leaders say vigilance is key. Lessons from past outbreaks have improved preparedness, but HPAI remains a real risk. The hope is for a quiet season, yet strong biosecurity will be the best defense as birds move through.
