Mother Jones published an alarming report about the revival of child labor, based on the work of the Food and Environment Reporting Network. Promoted by Republican governors despite federal law, child labor has become increasingly dangerous. Children are hired to replace adult immigrants and to keep costs low.

If you’ve eaten a burger and fries recently, there’s a chance that the potatoes were picked by middle schoolers, working through the school day in a field in Idaho. The steer that became the beef patty may well have been killed at a slaughterhouse where teenagers work, and the bone saws used to process the meat could easily have been cleaned by a 13-year-old, wearing a bulky hard hat and oversized gloves. It’s also quite possible that the burger was grilled, flipped and assembled by a child working at McDonald’s on a school night, far later than federal law allows.

This sort of child labor—culled from thousands of examples in U.S. Department of Labor investigations—has been mostly illegal in the U.S. since the 1930s, but that hasn’t stopped a surprising number of companies from engaging in it. In February, the department announced that the nation is experiencing a sharp rise in child labor violations across all industries; since 2018, the agency has documented a 69-percent increase in children who were employed illegally.

A FERN analysis of investigation data released by the Department of Labor’s Wage and Hour Division (WHD)—which is tasked with enforcing federal child labor laws—found that more than 75 percent of recent violations were committed by employers in the food industry. The agency uncovered more than 12,000 child labor violations in the nation’s food system—out of 16,000 total violations across all industries—between Jan. 1, 2018 and Nov. 23, 2022, the most recent date for which data were publicly available. Investigators found minors working illegally at vegetable farms in Texas and Florida, at dairy farms in Minnesota and New Hampshire and at poultry plants in Alabama and Mississippi. Children are involved in every step of the food supply chain, working illegally from farm to table…

Supermarkets and other food and beverage stores were well represented, too, responsible for 7.7 percent of the violations. In one particularly egregious example, from 2021, a 16-year-old supermarket worker in Clarksburg, Tennessee, was tasked with cleaning out a meat grinder, even though federal law prohibits employers from having minors clean or operate them. As the boy reached into the machine, the grinder switched on and ripped off half of his arm.

Who could have imagined that states and employers today would be rolling back protections for children enacted in the 1930s?
