health officials are warning about a potentially deadly condition linked to the countertop material found in millions of american homes. engineered stone, also called quartz, is popular because it's beautiful and can be made in a number of colors and finishes. but many of the workers who make those counters are getting sick from a material called silica. it can get in their lungs, leaving them to need lung transplants and at risk of death. anna westrner spoke with severa workers suffering from the deadly disease known as silicosis. >> once installed these products aren't dangerous to you the consumer. but if you're buying new countertops for your new home or renovation project, you should know, some workers are dying so you can have them. this wasn't what dennis williams expected at age 36. staying home instead of working, waiting for a lung transplant to save his life. >> translator: you live with the pain. it's an inexplicable pain. i have pain every day. >> reporter: the cause, sill koesis, a deadly lung disease

his doctors say resulted from work in a shop like this one, cutting and shaping countertops made of engineered stone. over the past decade engineered stone countertops made from crushed quartz have taken over the u.s. market. they come in a range of colors and patterns, and manufacturers talk up the product's advantages. >> resistant to cracks, stains, heat and chemicals. >> reporter: but compared to natural stone these slabs often contain much higher levels of crystalline silica, as much as 95%, a material that if inhaled can cause silicosis, which destroys the lungs. workers who cut and shape those slabs like these in videos we obtained, often work in a haze of silica dust, and many are now becoming sick. >> every week or every two weeks i hear about a new case here. >> reporter: dr. jane fazio is pulmonary critical care physician at a ucla medical center north of los angeles. >> for instanc, yesterday i had a patient, he had a cough he

didn't think anythig of. and i basically told him he was going to need a lung transplant or he was going to die in the next couple of years. >> this was the conversation you had with a man just yesterday. >> this is a conversation i have almost weekly. >> reporter: a study she led last year found in california nearly a fifth of the workers who got silicosis on the job die. >> it sounds like an epidemic. >> it definitely is. it's been epidemic. >> reporter: often it's immigrant latino workers paying the price. along with williams, now waiting for his transplant, there's 56-year-old arturo batista, a father of three who says he has to keep working despite being diagnosed with silicosis. >> translator: i know it's doing me harm. but i have nowhere else to work. >> reporter: and 34-year-old gustavo reyes gonzalez, who had to have a lung transplant last february. >> translator: there's very little possibility that my life lasts long. the transplant is for a few years, nothing more. >> reporter: did anyone ever tell any of you that you needed

protection from the dust? >> no. >> no. >> no. >> reporter: they're now suing. their attorney, james nevin. >> many of these workers are in their 20s, their 30s, their 40s. and they will be dead within a year if they don't get a lung transplant. the manufacturers knew all that. they knew exactly this is what was going to happen. >> reporter: the manufacturers declined to comment on the lawsuits. an industry group, the silica safety coalition, said exposure to silica dust is preventable if fabrication shops comply with state and federal osha regulations and requirements. another, the engineered stone manufacturers association, said licensing programs and enhanced regulatory oversight are the keys to protecting workers. but in december australia banned engineered stone finding compliance in the industry was insufficient and the product poses an unacceptable risk to workers. so what's it like in fabrication shops here? on this short street in an industrial area north of los

angeles we walked past roughly a dozen independent fabrication businesses and watched as the dust flew. when you look in these shops are you seeing the kind of protection that you would want to see mostly? >> no. no. >> reporter: on another street not far away 33-year-old joseph mondragon invited us into the stone-cutting shop his father started 40 years ago. as workers cut into slabs. the workers do try to keep the dust down in here, but literally it's everywhere. mondragon says he's been around the shop since he was 15 but is just now getting warnings about the dangers of engineered stone cutting. >> it's scary just to know that we're out here making a living and we could get sick over some dust that we didn't really have no knowledge of. >> reporter: just two weeks ago dennis williams finally got a double lung transplant. doctors say if he's lucky it may let him live to his mid 40s. >> translator: i wouldn't wish

this on my worst enemy. >> this doesn't need to be happening. this is a completely preventable disease and it's killing people that all they want to do is go to work and provide for their families every day. you have the right to go to work and have your work not kill you, right? >> reporter: yes. cesar stone told us the health and safety of our employees, supplies and partners is our top priority. california has put temporary emergency regulations in place to try to protect workers. one of those manufacturers, koesenteeno, says it now exclusively sells lower silica products of 10% and 40%. but australian officials said in their report it's not clear how protective those lower levels are for workers. there's a lot more news ahead on the "cbs overnight news."
