Portugal Lifts Bird Confinement Orders: What Poultry Farmers and Residents Need to Know

Portugal's agriculture regulator has lifted mandatory bird confinement orders across risk zones, signaling a cautious return to normal operations for the country's poultry sector after months of heightened alert. The Direção-Geral de Alimentação e Veterinária (DGAV) made the move following a sharp decline in highly pathogenic avian influenza (HPAI) outbreaks across the European Union, though officials warn the virus has not disappeared entirely.

Why This Matters

• Poultry farmers and backyard bird keepers in previously restricted zones can now allow outdoor access, reducing confinement costs and improving animal welfare.

• Strict biosecurity protocols remain mandatory, including species separation at markets and commercial transport permits—non-compliance risks fines and renewed lockdowns.

• The virus is still circulating among wild bird populations, making spring and autumn migration periods high-risk windows for future outbreaks.

• Spain has taken a different path, lifting national restrictions but maintaining confinement in high-risk zones.

The Numbers Behind the Easing

Since the current 2025/2026 avian flu season began on October 1, Portugal has confirmed 26 infection clusters: 16 in domestic flocks and 10 among wild birds, according to DGAV data. By comparison, Portugal logged 53 total outbreaks in 2025, making the current season's infection rate lower than the previous year.

The Portuguese veterinary authority emphasized that the seasonal downturn aligns with typical epidemiological patterns: as migratory waterfowl disperse in spring and temperatures rise, transmission pressure naturally decreases. Yet officials caution that complete viral eradication is "unlikely," particularly with the H5N1 subtype persisting in wild populations across Europe.

What This Means for Poultry Operators

The lifting of confinement does not equate to a regulatory free-for-all. DGAV's latest edict maintains stringent biosecurity frameworks that apply to everyone from backyard hobbyists to industrial-scale egg producers. Here's what remains in force:

Market and Fair Regulations: Live poultry sales at fairs and public markets must observe mandatory species separation—chickens cannot share stalls with ducks, geese, or swans. Only visibly healthy birds may be displayed, and vendors must maintain three-month records identifying all traders, workers, bird quantities, and any health incidents. Floors must be covered with tarpaulins or plastic sheeting to prevent ground contact, and transport cages must transfer directly to sale enclosures without touching surfaces.

Commercial Transport Licensing: Movement of live birds for trade now requires explicit DGAV authorization. Birds must travel in enclosed cages or boxes inside vehicles, and transport compartments must be sealed on all sides and the roof to block wild bird contact.

Biosecurity Fundamentals: Farmers are urged to limit farm access to essential personnel only, disinfect footwear and equipment regularly, and immediately report any unusual mortality or respiratory symptoms. Water sources should be treated, and facilities must prevent wild bird intrusion through netting or enclosed housing.

Regional Approaches Across Europe

Portugal's veterinary authority has adopted a cautious stance, reflecting a prioritization of precautionary containment measures amid incomplete viral clearance and the proximity of migratory flyways that traverse the Iberian Peninsula. While neighboring countries have pursued different timelines for restrictions, DGAV emphasizes the need for sustained vigilance given the persistence of the H5N1 strain.

The European Commission regularly updates protection and surveillance zones—typically 3 km and 10 km radii, respectively, around confirmed cases—requiring member states to cull infected flocks, restrict movements, and conduct enhanced monitoring across the continent.

The Seasonal Outlook

Spring typically brings a lull in avian flu activity as waterfowl disperse from wintering grounds, reducing viral concentration and transmission opportunities. However, the 2025/2026 season's elevated baseline means the virus remains a concern, and epidemiologists caution that autumn could see renewed pressure as migrating flocks return.

Wild bird surveillance programs operated by DGAV and partner agencies will be critical for early warning, allowing preemptive measures before commercial farms are exposed.

Practical Guidance for Residents

For backyard poultry keepers, the rule changes mean outdoor access is again permitted, but contact with wild birds must be prevented at all costs. Simple measures include covering outdoor runs with netting, removing standing water that attracts waterfowl, and feeding birds indoors to avoid attracting corvids and pigeons. Any sudden deaths or respiratory distress should trigger immediate DGAV notification via the agency's hotline or online portal.

Consumers will see limited immediate impact at supermarket egg and poultry counters, though prices may reflect recent market conditions. Free-range and organic egg availability should gradually improve as farms resume outdoor production cycles.

Pet bird owners and ornamental poultry enthusiasts should verify that any birds purchased at markets come with health documentation and avoid mixing species. The three-month vendor record retention requirement creates an audit trail for contact tracing should outbreaks occur.

Why Biosecurity Remains Non-Negotiable

The DGAV edict underscores that compliance with biosecurity protocols is "essential for safeguarding animal welfare"—a reality that reflects the stakes involved: a single undetected infection can trigger regional lockdowns, mandatory culls, and export bans that impact the sector. The H5N1 strain circulating in Europe has proven persistent, surviving longer in the environment than previous variants.

International best practices, as outlined by the World Organisation for Animal Health (OIE), emphasize layered defenses: physical barriers, hygiene protocols, visitor restrictions, pest control, and rapid disease reporting.

Looking Ahead

Portugal's poultry sector can cautiously resume normal operations as confinement lifts, but the respite may prove temporary. The virus's trajectory remains unpredictable, and continued vigilance is essential. For now, the message from Portuguese agricultural authorities is clear: the crisis has eased, not ended. Farmers who maintain discipline on biosecurity will be best positioned for whatever comes next.
