Concerns Over Bird Flu Outbreak at Utah Mink Farm

An outbreak of bird flu at a mink farm in Utah has raised concerns among infectious disease experts regarding the government’s ability to manage such viral threats. This situation and how it has been handled have sparked discussion about transparency, especially from officials during the Trump administration.

According to Jennifer Nuzzo, an epidemiology professor and director at Brown University School of Public Health, the risks of the virus spreading to humans are low, but the lack of clear communication from the government is alarming. “No animal or human will be protected from the toll of this virus through secrecy,” she remarked in a phone interview. “The most at risk are those who come into contact with sick animals. If you’re not in that group, you can relax a bit, but it doesn’t mean the government shouldn’t take steps to prevent a potential pandemic.”

This bird flu outbreak has persisted for about two months at a farm located roughly an hour from Salt Lake City, reportedly where thousands of mink are raised for their fur, according to a ProPublica report from earlier this week.

A state veterinarian, Amanda Price, initially attempted to address the situation and sought assistance from the US Department of Agriculture (USDA), but federal officials indicated they don’t regulate mink and don’t have an approved vaccine for them, as noted by ProPublica through public records obtained from the state.

The USDA has not yet responded to inquiries regarding this matter.

Officials from the Centers for Disease Control and Prevention (CDC) did engage with local health department staff in Utah but did not directly communicate with Price, as reported by ProPublica.

In other nations that have dealt with similar outbreaks, government actions included ordering the culling of infected mink. Veterinarians suggested that such measures should have already been taken at the Utah farm.

This isn’t the first time Utah has faced a similar outbreak; during the Covid-19 pandemic, nearly 10,000 mink in the state succumbed to the coronavirus, leading to quarantines across nine farms.

It is believed that the virus may have been transmitted to the mink from infected workers, as discussed in a journal article. Mink have shown significant susceptibility to various viruses that can also affect humans, according to another research publication.

Nuzzo expressed that she hasn’t observed any evidence suggesting the virus is spreading among humans at this time. “What I’m most concerned about is the potential for workers exposed to sick animals to become ill, and some could die. This is particularly troubling because we could possibly avert that outcome by considering vaccination for farm workers, as is done in other countries,” she noted.

There’s also the risk that the virus could lead to a pandemic if it were to merge with an influenza virus, a concern that heightens during flu season when various influenza strains are circulating. “I can’t specify the probability of that happening. It could be zero,” she added.

A representative from the fur trade voiced concerns to Price about the impacts of culling the mink on their business and the overall industry. However, Tom Peacock, an avian influenza researcher, remarked that in such situations, swift depopulation is the norm, and the delay in this case is quite concerning.

Reportedly, officials have not been monitoring farm workers for symptoms, contrary to CDC recommendations. ProPublica identified two individuals working at the farm, one of whom exhibited symptoms such as a red eye, which the CDC suggests should be tested for.

Price and the Utah department of agriculture and food have not yet commented on the situation.

The owner of the farm, Chad Fenn, claimed the worker’s symptoms were due to dust in their eye and stated that the health department did not suggest testing.

Nuzzo has raised concerns about a reduced level of monitoring on farms for potential viruses under the Trump administration compared to previous administrations. “After Trump took office, his administration let go of federal employees who were addressing a bird flu outbreak among dairy cows,” she pointed out.

Nuzzo noted that there used to be regular communication between federal officials and disease experts to keep them informed about ongoing efforts, which appears to have diminished. “Those discussions were valuable since they allowed us to inquire further and challenge some of the ideas,” she observed. “Losing that communication means vital information could be missed, and necessary actions may not receive the scrutiny they need.”
