Organizers of the event said the giant sushi roll included 200 pounds of dry rice, 80 pounds each of
cucumber and avocado, and 180 pounds of fish along with several pounds of tofu used to make a vegetarian section of the giant dish, the Oakland (Calif.) Tribune reported Monday.
University spokeswoman Kathleen Maclay said the roll beat the previous world record of 300 feet, set in 2001 in Hawaii.
Professor Duncan Williams said the event is part of the school's festivities celebrating the 50th anniversary of the University of California-Berkeley's Center for Japanese Studies.
"A lot of what we're talking about is Japanese hybrids, where Japan meets the world. The California roll is a good example of that," Williams said.
