A traveler found maggots on his sandwich at the Atlanta airport, according to USA Today.

Joel Woloshuk, a weekly traveler, was about to eat a sandwich that he bought at Caffe Intermezzo when the flakes that he thought were parmesan cheese began wriggling on his sandwich, he told WSB-TV.

The restaurant has since switched bread vendors and "not a single crumb" from the original bakery remains, according to a statement that the president of Caffe Intermezzo told WSB-TV. According to him, the problem couldn't have started at the restaurant.

Ultraviolet lights are being distributed to restaurants at Hartfield-Jackson International Airport restaurants to allow them to inspect their food shipments more thoroughly. Regular inspections are conducted at the airport by the Atlanta Department of Aviation.

No citable violations were found at the location that was inspected, according to the Clayton County Board of Health.

La Petit France bakery was the bread vendor for the restaurant, based in Marietta, Georgia, according to a report from the television station. An inspection from the Department of Agriculture report listed several critical violations that had been found by inspectors. They found the facility was dirty and in poor physical shape during the inspection and found that the food processing areas weren't free of pests, rodents or insects.

A cease and desist order had been recently issued in reaction to the inspection. The department later lifted the order.

The president of La Petit France told the television station that the bakery was clear to distribute bread and that the issue couldn't have originated at the bakery. The bakery is distributing to other restaurants.

It is still unknown where the maggots came from, officials in the Department of Agriculture said. While both the restaurant and the bakery say they can't be the origination point, the maggots had to come from somewhere and further inspections will help determine the origin.
