Restaurant executives say they've switched vendors after a customer found a cluster of maggots on his sandwich at Atlanta's airport.

Joel Woloshuk told WSB-TV Tuesday that he bought a sandwich from Café Intermezzo at the airport 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 officials said Woloshuk's case was an isolated incident that could not have originated at the restaurant. Officials say they switched bread vendors, although the vendor told the television station the Department of Agriculture inspected them late last week.

Department of Aviation officials say they're distributing ultraviolet lights to airport restaurants so they can better inspect food shipments, and will visit area vendors to inspect for violations.
