"GRAND RAPIDS, Mich. — A medical-device manufacturer said it will stop sterilizing equipment at a Michigan facility as state regulators investigate the company for air pollution, including for the release of a known carcinogen.
Viant Medical announced in a letter to residents this week that by the end of the year, it will discontinue sterilizing equipment and the use of ethelyne oxide at its Grand Rapids facility.
The colorless and odorless gas is known to cause breast and blood cancers, the state Department of Health and Human Services said."
