(AP) — The U.S. Department of Labor has fined Hy-Vee, Fareway and other grocery stores in Iowa and Nebraska nearly $130,000 for violating child labor laws.

The Labor Department announced the fines Thursday.

The department says the violations included allowing workers under 18 to perform hazardous jobs that are prohibited. That included loading or operating power-driven paper balers, meat slicers, bakery machines and motor vehicles. No underage workers were injured.

The Labor Department report says Hy-Vee was assessed $68,200 for 27 violations at seven stores, while Fareway was assessed nearly $20,000 for 13 violations at eight stores. The violations would have happened since October 2011.

Representatives of Hy-Vee and Fareway say the stores are committed to maintaining a safe environment for young workers.
