U.S. Secretary of Health Robert F. Kennedy Jr. has asked the president of the Canadian Food Inspection Agency (CFIA) to reconsider plans to cull birds at a B.C. ostrich farm.
The birds at Universal Ostrich Farms Inc. were exposed to avian flu and the CFIA has directed the more than 400 birds at the farm to be culled. However, the farm owners say the birds are valuable for research purposes as they likely have antibodies to the virus.
Kennedy also said in his letter to CFIA president Paul MacKinnon that the animals present an opportunity for long-term research on avian flu for both countries.
“It’s our hope that this collaboration will help us understand how to better protect human and animal populations and perhaps lead to the development of new vaccines and therapeutics,” he said in the May 23 post on the X platform.
The letter, signed by Kennedy, Bhattacharya, and Makary, asked the CFIA “to consider not culling the entire flock.”
“Given that a proportion of these ostriches were infected with avian influenza (H5N1) last year we believe there is significant value in studying this population,” they wrote.
“Avian flu is a shared threat that we jointly face.”
They gave several reasons not to cull the animals, including that the flock was in a controlled environment that would be optimal for long-term research. They also said the bird’s antibody levels and immunity were scientifically valuable.
Kennedy, Bhattacharay, and Makary offered “full support and assistance” in diagnostic testing and long-term research of the animals.
They noted that avian influenza is endemic in wild birds in Canada and the United States, and culling the ostriches would not effectively eliminate it.
They also said said the ostriches provide an opportunity to build knowledge about the virus.
“The indiscriminate destruction of entire flocks without up-to-date testing and evaluation can have significant consequences, including the loss of valuable genetic stock that may help explain risk factors for H5N1 mortality,” the letter said.
They said H5N1 does not “persist in birds indefinitely,” noting that it has an incubation period of between three and seven days, and added that because the birds have not shown symptoms for some time, to cull them is a “disproportionate measure.”
The owners of the farm in Edgewood, B.C., have said the birds have developed herd immunity and are being used for research.
The CFIA acknowledged that the risk to humans is low, but also said some serious cases and even death have been recorded in North America. It said that “depopulation” of infected birds is one of the strict biosecurity measures required to manage outbreaks.
The family that runs the farm recently lost a judicial review of the CFIA decision, but had been granted an injunction of the action until the outcome of the court.
The CFIA said on May 14 that it would still move ahead with plans to cull the animals but would not be publicly releasing the date it would do so.
