According to reporting from ProPublica, a cluster of avian flu on a mink farm in Utah has largely gone unchecked for the last two months and has the potential to crossover to humans.1

The report says that Utah state officials became aware in mid-August of avian flu-related deaths among mink kept on a farm south of Salt Lake City.1 However, ProPublica reports that no mink-specific federal containment protocols exist for bird flu outbreaks, so the animals were not “depopulated,” allowing mink infections and deaths to grow.1

In the report, mink are described as a potential “crossover” vector for avian flu to transfer across species from birds to humans, as mink share cellular similarities and are vulnerable to viruses that infect both birds and humans.1

“Mink have lungs and airways that on a cellular level are remarkably similar to those of people,” the ProPublica report states, adding that mink have infected humans with other influenza viruses and COVID-19.1 All that’s needed for cross-species avian flu infection is contact with humans, and time.1

“[The] perfect petri dish exists right now,” the ProPublica report states.1

Despite the dangers, ProPublica says “state and federal officials have done little except try to keep its existence quiet.” 1

According to ProPublica, containment measures on poultry farms where avian flu is detected are quickly implemented and entire flocks can be culled.1 However, the lack of federal containment guidance for mink farms along with the business interests of the local mink farming industry have led to inaction, according to the report.1

The threat of spillover has been far from the minds of Utah officials, records and interviews show. Instead, front and center have been the interests of a business raising animals to skin for luxury pelts to ship overseas.1

According to the CDC, 72 human cases of A(H5) avian flu have been detected in the United States since February 2024, with the majority of exposure vectors being dairy cows.2

To date, no mink-to-human avian flu infections, or any human cases at all, have been reported in Utah, CDC data show.2

However, health officials are reportedly not monitoring mink farm workers for possible infection, despite CDC recommendations.1 According to ProPublica, Utah state policy does not impose active health monitoring unless human-to-human transmission of avian flu is detected.1

Until then, individuals must seek testing or care.1

The failure to act amounts to a cascade of missteps flu experts called “irresponsible’’ and “puzzling.’’ One called it “playing with fire.” 1
