A restaurant says it has switched vendors after a customer found a cluster of maggots on his sandwich at Atlanta's airport.

Weekly traveler Joel Woloshuk told WSB-TV Tuesday that he bought a sandwich from Café Intermezzo and realized the white specks on top of it were maggots — not parmesan — when they began moving.

In a statement to WSB-TV, Café Intermezzo's president said the case was isolated and the problem could not have originated at the restaurant. He says the restaurant switched bread vendors and "not a single crumb" from the original bakery remains.

Atlanta Department of Aviation officials say they're distributing ultraviolet lights to Hartsfield-Jackson International Airport restaurants so they can better inspect food shipments.

The Clayton County Board of Health says it found no citable violation at the location that it inspected.
