HARLEM, Manhattan — When Idelis Quinones' 1-year-old grandson refused to drink his juice, she nothing of it at first.
But after inspecting the juice carton and opening it up, what she discovered was disturbing -- a mysterious black sludge lining the bottom of the box.
"I couldn't believe what was inside. I am so grateful he didn't drink it," Quinones said.
Quinones said she received the juice box free at Lasker Pool, inside Central Park, as part of the Summer Meals program. It's part of a city program that provides free food to children.
What made this grandmother even more angry is when she tried calling the Department of Education to complain, she said she was told several times to call back.
"Infuriating. That's why I called you," Quinones said.
PIX11 News reached out to the Department of Education.
They took immediate action, looking into alternative packing options, and have dispatched a quality assurance specialist.
"We are dedicated to ensuring the quality and health of all food that's served, and are investigating an incident that was reported. There were no reported injuries or serious health risks and we are working diligently to ensure it's addressed," the agency said in a statement.
