BioSec Bob here on Sunday, May 17, 2026 — let’s get right into it.
The world’s largest egg exporter is moving to vaccinate its flocks against bird flu, according to The Animal Reader. The operation’s decision to implement vaccination across its chickens represents a significant shift in how the industry’s top producer is managing avian influenza risk. Details on the timing and scope of the vaccination rollout are still emerging, but the move signals confidence in vaccine availability and effectiveness as a control strategy at commercial scale.
On the poultry disease front, Poultry World is reporting on Salmonella Infantis — a strain that’s proving remarkably stubborn to control. The bug’s resilience in production environments has made it a persistent challenge for integrators and independent operators alike. Salmonella Infantis continues to survive standard cleaning and disinfection protocols better than many competing strains, which is keeping it at the top of the concern list for food safety and flock health.
Moving across to the swine side, the Canadian Food Inspection Agency is warning producers about pseudorabies outbreaks detected in U.S. commercial swine operations, according to unpublished.ca. The CFIA alert specifically flags activity in American herds and is advising Canadian producers to review their biosecurity measures and sourcing practices. Pseudorabies can cause severe reproductive failure and neurological disease in affected pigs, so the agency’s warning carries real weight for operations near the U.S. border.
Back to poultry — Feedstuffs is reporting that a more potent strain of bird flu is emerging in the field. The heightened virulence presents a different threat profile than producers have been managing, and the development underscores why vaccination discussions like the one from the world’s top egg exporter are gaining urgency.
The CDC is also weighing in on poultry-linked disease. According to NTD News, a Salmonella outbreak connected to poultry has now reached 184 cases, with children under five making up a disproportionate share of the sick. The outbreak is still under investigation, but it’s putting fresh pressure on producers to demonstrate food safety controls from farm to consumer.
Lastly, Swiss authorities are signaling serious concern about African swine fever risk, as reported by aa.com.tr. Switzerland’s government is warning of a high probability that ASF could spread into the country, likely from neighboring regions where the disease is already established. Swiss producers are being advised to heighten vigilance and prepare containment protocols.
Keep your vaccination records and biosecurity logs current — it’s a critical season.
