The Subway tuna sandwich saga continues: Food writer Corby Kummer joined Boston Public Radio to discuss new claims in a lawsuit against the sandwich chain that its tuna subs don’t contain tuna at all.

“This is one of the best stories ever,” he said. “Everybody wants to test Subway tuna sandwiches and find out what’s in it.”

Earlier this year, the tuna-sandwich-lawsuit.html">New York Times sent out samples of Subway tuna sandwiches to a laboratory, only to find that “no amplifiable tuna DNA was present” and the species couldn’t be identified.

Subway has repeatedly denied the allegations.

Corby Kummer is executive director of the Food and Society policy program at the Aspen Institute, a senior editor at The Atlantic and a senior lecturer at the Tufts Friedman School of Nutrition Science and Policy.
