The U.S. Department of Labor recently uncovered violated child labor restrictions in some McDonald’s locations within the states of Texas and Louisiana.

Investigations found the violations impacted 83 minors between 14 and 15 years old in 16 locations, the Department of Labor disclosed in a press release.

In Louisiana, investigators with the Department of Labor’s Wage and Hour Division discovered that CLB Investments LLC, the company that operates the restaurants and is based in Metairie, Louisiana, allowed 72 workers between the ages of 14 and 15 to work longer and later than permitted. This occurred at 12 restaurants located in Kenner, Jefferson, Metairie and New Orleans.

The employer allowed three children to operate manual deep fryers, which should only be used and operated by employees 16 and older, the Department of Labor’s investigation found.

“The department assessed CLB Investments with $56,106 in civil money penalties for violations found at 12 locations, one of which is now closed,” the press release said.
