Dozens of youth under the age of 20 die on the job each year, reveals report.
"We don't tend to think of child labour as a major issue in the U.S. but we should," said the study's lead author Carol Runyan, Ph.D., MPH, and professor of epidemiology at the Colorado School of Public Health.
"Laws governing the employment of youth ages 14 to 17 in this country are often very lenient and in the case of family farms virtually non-existent," Runyan noted.
Runyan, who led a group of American and Canadian scholars and public health professionals on the project, is now calling for stricter oversight of working conditions for the young including those employed in agriculture.
"Work can help young people develop skills, explore career options, earn money and gain self-esteem. But without adequate safeguards in place, work can also be dangerous for youth," she said.
The report found that 88 youths under age 20 died from work-related injuries in 2010 while 20,000 missed work in private industry due to occupational-related illness or injury.
Runyan said that while work holds many positives for young people, it could also expose them to unsafe tasks and environments with limited supervision.
"For example, a recent national U.S. study reported that 26 percent of workers younger than 18...worked at least part of the day without an adult supervisor and as many as one-third of them reported not having any health and safety training," Runyan said.
Working youths are at risk in many ways. They can be burned in fast food restaurants, cut by sharp tools in grocery stores, robbed at retail businesses, fall from roofs at construction sites or be involved in traffic collisions. But one of the most dangerous occupations, Runyan said, is farm work.
"From a fatality standpoint, farm work is the most dangerous occupation for kids. In farm work, youths are working around heavy equipment, digging and cutting with sharp implements. There are deaths almost every year from young people suffocating in grain bins," she said.
Youths working on family farms have practically no legal protections and often drive while underage and operate tractors and other heavy equipment.
Runyan and colleagues John Lewko, Ph.D., of Laurentian University in Ontario and Kimberly Rauscher, ScD, of West Virginia University, are using the report to advocate for stronger federal monitoring of youth worker safety, including assuring that children working on farms are better protected.
They are also encouraging more research into preventing workplace injuries among young people.
Runyan also stressed the need for parental involvement.
"We need to make sure that the jobs our kids take are safe. But ultimately it's not the responsibility of 15-year-olds to ensure their safety -it's the responsibility of employers," she added.
The report was published last week in Public Health Reports.
