More than two dozen asbestos-related deaths have been linked to the manufacture of asbestos-containing construction materials.
The deaths occurred in California and New Jersey over the last decade, the Centers for Disease Control and Prevention said.
The first death was in 2008 in North Carolina, when a construction worker died from a form of the carcinogen.
Another worker died in 2012 in Indiana after inhaling the fibers from the home insulation, which are not considered asbestos.
In January, a Pennsylvania worker died after inhaled asbestos fibers.
The Associated Press reported that a construction company in Pennsylvania, where the deaths occurred, recalled its products because the company discovered that asbestos fibers could be found in the air, soil and water.
A new test released in May found that the new asbestos was not asbestos.
But that doesn’t mean it’s safe to use, experts say.
A study in 2014 found that more than 2 million people in the U.S. have been exposed to asbestos fibers in the building trades, said Dr. Paul DeSantis, director of the Department of Occupational and Environmental Medicine at Johns Hopkins University School of Medicine.
A similar study of the industry’s fibers in Pennsylvania found that 4 percent of the state’s workers had exposure to asbestos, DeSants said.
More than 3 million Americans were estimated to have asbestos-contaminated work spaces in the 1970s, 1980s and 1990s, DeAntones said.
About 3.7 million people were exposed to the fibers as of last year, according to the American Society of Civil Engineers.
There have been two recent deaths linked to asbestos.
One was found in 2014 in Ohio, when the death was attributed to inhaling asbestos fibers from a home insulation.
The other was in North Dakota in 2016.
In California, two workers died of exposure in 2016 to asbestos found in their homes.
In New Jersey, one worker died of inhaling fibers from his home insulation after an asthma attack.
The AP has reached out to the construction company that manufactured the insulation.
We will update this story if and when we hear back.
