Recent analysis, detailed in an affidavit by CFIA Deputy Chief Veterinarian Cathy Furness, has revealed the presence of a “novel reassortment” of the H5N1 virus on the farm. This new iteration of the virus demonstrates “enhanced pathogenicity,” exhibiting a heightened ability to cause disease. Laboratory tests at Canada’s National Microbiology Laboratory indicated that even low doses of the strain proved fatal to mice within a matter of days. Despite this finding,the CFIA acknowledges uncertainty regarding the current infection status of the ostriches.
Farm Owners Dispute Culling Order
Universal Ostrich Farms vehemently opposes the cull, arguing the birds are healthy and have acquired “herd immunity” following the initial outbreak in December 2024, which resulted in the loss of 69 birds. Katie Pasitney, a spokesperson for the farm and daughter of a co-owner, stated the farm is actively responding to legal filings from the Justice Department. The farm has secured a temporary stay of the cull order, pending a hearing at the supreme Court of Canada.
Concerns Over ‘Silent Shedding’ and Environmental Risk
The CFIA’s affidavit raises concerns about the potential for “silent shedding” of the virus, where infected ostriches continue to transmit the virus through urine, feces, and respiratory secretions even without displaying symptoms. This phenomenon, also observed in species like ducks, complicates efforts to contain the outbreak. Furthermore, the agency highlights the virus’s persistence in the environment – surviving for months in water and up to six months in manure and feathers – posing a sustained risk of reinfection.
High-Profile Support and scientific Debate
The case has garnered attention from prominent figures, including U.S. health officials Robert F. Kennedy Jr. and Dr. Mehmet Oz, who has publicly advocated for the ostriches’ preservation and even offered to relocate them. However, experts remain skeptical about the claim of unique immunity within the flock. The debate underscores the challenges in understanding avian influenza dynamics and the evolving nature of viral threats. The farm maintains the birds are scientifically valuable and pose minimal risk.
Here’s a summary of the key details in this ongoing case:
| Aspect | Details |
|---|---|
| Location | Edgewood, British Columbia, Canada |
| Farm Name | Universal Ostrich Farm |
| Number of Birds | Approximately 400 |
| Virus Strain | Novel reassortment of H5N1 avian influenza |

Understanding Avian Influenza
Avian influenza, commonly known as bird flu, is a highly contagious viral infection that affects primarily birds, but can sometimes spread to mammals. Several strains exist, ranging in virulence, with some posing a significant threat to poultry industries and public health. The H5N1 strain,in particular,has been a source of global concern due to its potential for causing severe illness and its ability to mutate. According to the World Health Association, ongoing monitoring and research are critical for understanding and mitigating the risks associated with avian influenza viruses.

What specific physiological characteristics of ostriches may contribute to their increased susceptibility to this HPAI strain?
Higher Lethality of avian Flu Confirmed at British Columbia Ostrich Farm: CFIA Vet Analysis
Avian Influenza Outbreak Details – BC Ostrich Farm
A recent outbreak of Highly Pathogenic Avian Influenza (HPAI) at an ostrich farm in British Columbia has been confirmed by the Canadian Food Inspection Agency (CFIA), with a notably higher mortality rate than previously observed in poultry outbreaks.The CFIA’s veterinary analysis points to specific vulnerabilities within ostrich populations to this particular strain of the virus. This incident underscores the evolving threat of avian flu, also known as bird flu, and the need for heightened biosecurity measures across all avian species.
CFIA Veterinary Findings: Increased Ostrich Mortality
Initial reports indicated a significantly higher percentage of ostriches succumbing to the HPAI virus compared to typical poultry like chickens or turkeys. The CFIA veterinary team’s examination revealed several contributing factors:
Unique Physiological Characteristics: ostriches possess a different immune response system than traditional poultry, potentially making them more susceptible to severe illness from this specific HPAI strain.
Viral Load & Replication: The virus demonstrated a rapid replication rate within ostrich respiratory systems, leading to acute pneumonia and systemic infection.
Delayed Symptom Recognition: Early symptoms in ostriches can be subtle, delaying intervention and increasing the likelihood of mortality. Common signs include lethargy, decreased appetite, and respiratory distress.
Strain Specificity: The H5N1 strain currently circulating appears to exhibit increased pathogenicity in ratites (ostriches,emus,rheas,and cassowaries).
Understanding the HPAI strain & Spread
The confirmed strain is a Eurasian H5N1 avian influenza virus. This particular subtype has been responsible for widespread outbreaks globally,impacting wild bird populations and domestic poultry.The spread to the BC ostrich farm is believed to have originated from migratory waterfowl,a common vector for avian influenza transmission.
Wild Bird Involvement: Migratory birds, particularly waterfowl, act as reservoirs for avian influenza viruses.
Farm biosecurity Lapses: While the investigation is ongoing, potential biosecurity breaches on the farm are being examined as contributing factors. This includes assessing visitor protocols,equipment sanitation,and pest control measures.
Environmental Contamination: The virus can survive in the environment for varying periods, particularly in cooler temperatures and moist conditions.
Biosecurity Measures for Ostrich Farms & Avian Owners
Following this outbreak,the CFIA has reinforced the importance of stringent biosecurity protocols.These measures are crucial for preventing further spread and protecting other avian populations.
Restricted Access: Limit access to the farm to essential personnel only.
Foot Baths & Disinfection: Implement rigorous foot bath and disinfection procedures for anyone entering the farm premises.
Vehicle Sanitation: Thoroughly clean and disinfect all vehicles entering and leaving the farm.
Wild Bird Control: Minimize contact between domestic birds and wild birds. This includes netting enclosures and removing potential food sources that attract wild birds.
Regular Monitoring: Implement a robust health monitoring program for all birds, including daily observation for signs of illness.
Reporting Suspect Cases: Immediately report any suspected cases of avian influenza to the CFIA.
Impact on the Ostrich Industry & Meat Supply
The outbreak has resulted in the culling of the entire ostrich flock at the affected farm to contain the spread of the virus. This has a localized impact on the ostrich meat supply chain.
Supply Chain Disruptions: The loss of the flock will temporarily reduce the availability of ostrich meat in the region.
Economic Consequences: The outbreak represents a notable economic loss for the farm owner and potentially impacts related businesses.
Consumer concerns: While ostrich meat is safe to consume if properly handled and cooked, the outbreak may raise consumer concerns about food safety. The CFIA assures that there is no evidence of human infection from this outbreak.
Avian Flu & Human Health – Risk Assessment
While the primary concern is the health of avian populations, the potential for zoonotic transmission (spread from animals to humans) is continuously monitored.
Low Human Infection Risk: The current H5N1 strain has a low risk of transmission to humans. However, the virus is constantly evolving, and ongoing surveillance is critical.
Precautions for Handling Birds: Individuals handling potentially infected birds should wear appropriate personal protective equipment (PPE), including masks, gloves, and eye protection.
Thorough Cooking: Thoroughly cooking poultry and ostrich meat to an internal temperature of 165°F (74°C) will kill the virus.
