April 22, 2022
NIOSH Update:


Welder’s anthrax is a newly identified, rare but serious disease. Welder’s anthrax is a pneumonia in a metalworker caused by bacteria that produces anthrax toxin. Seven patients diagnosed with what is now termed welders anthrax were reported to the Centers for Disease Control and Prevention (CDC) from 1994–2020. The job title of six patients was welder, and the job title of the seventh was metalworker. This is the first report to describe this newly identified occupational disease and provide additional information on cases, describe possible infection mechanisms, and outline ways to prevent welder’s anthrax in the workplace.
