Louisiana Alcohol and Tobacco Control agents issued eight citations to vendors at this year’s New Orleans Jazz and Heritage Festival for selling alcohol to minors, the agency said Wednesday.

ATC Commissioner Troy Hebert said the illegal sales, made to 16- and 17-year-olds working undercover for the agency, were the exception to the norm. Of the 70 compliance checks the agency conducted, 62 underage sales were refused, he said. Those vendors received awards from the ATC for following the law.

“Considering the size of this event and the amount of alcohol consumed, this year’s festival was handled very responsibly,” Hebert said in a news release.

The agency’s compliance checks spanned both weeks of the festival.

ATC agents provided booths selling alcohol with sample photographs of “vertical and horizontal driver’s licenses to assist servers in what to look for when checking identification cards,” Hebert said.
