Justin Clemons was at a Subway in Franklin, Indiana on Monday with his family, and they kept hearing a buzzing sound.

Eventually they figured out what it was: An employee was using a bug zapper to kill a bunch of bugs behind the counter, right over the food.

Justin took a video and posted it on Facebook:

Someone passed it along to the owner of the Subway who shut the place down the next day. He had the staff throw everything away and brought in a cleaning service to sanitize the entire place.

The health department also went there on Tuesday and found a bunch of fruit flies. They only gave the store a warning, not a fine. They reopened yesterday.
