More than 90 employees at an Upper Peninsula paper mill in Michigan are believed infected with a fungus found in soil and decaying wood, with about a dozen requiring hospitalization.
Investigation of a blastomycosis outbreak at the Billerud paper mill in Escanaba is ongoing and involves local, state, and federal health and occupational safety officials. The mill employs about 900 people.
“I’ve been at the paper mill for about 11 years, and we have never seen anything like this,” said Gerald Kell, president of the United Steel Workers Local 21 union that represents about 670 of the mill’s employees.
A blastomycosis outbreak affecting large numbers of people is highly unusual, as the fungal disease is not typically transferred from person to person.
It indicates that instead, scores of employees were infected from the same materials containing the blastomyces fungal spores, which exist in the environment in the eastern U.S. and parts of Canada.
People contract blastomycosis after breathing in microscopic fungal spores from the air, often after participating in activities that disturb the soil, according to the U.S. Centers for Disease Control and Prevention.
