The West Michigan Whitecaps say they have no plans to put a warning label on an enormous new hamburger they're selling this season — despite a vegan advocacy group's request to do just that.

Susan Levin, a staff dietitian for the Washington-based Physicians Committee for Responsible Medicine, sent a letter to the Grand Rapids minor-league team on Tuesday. She's asking that the 4,800-calorie burger be labeled a "dietary disaster" that increases the risk of cancer and heart disease.

The 4-pound, $20 burger features five beef patties, five slices of cheese, nearly a cup of chili and liberal doses of salsa and corn chips — all on an 8-inch bun.

Whitecaps spokesman Mickey Graham says the burger is a gimmick that's being promoted as a very unhealthy menu item.
