Hot dogs may be as American as baseball and apple pie, but an anti-meat advocacy group says they're hazardous to your health and should carry warning labels.

The Cancer Project, an offshoot of a pro-vegetarian organization, wants to force hot dog makers to use warning labels. The organization filed a lawsuit Wednesday in New Jersey.

It names Kraft Foods Inc., manufacturer of the Oscar Mayer brand; Sara Lee Corp.; Nathan's Famous; and the makers of the Hebrew National and Sabrett brands.

The lawsuit cites a report by the American Institute for Cancer Research that concluded regular consumption of processed meat can increase the risk of colorectal and other forms of cancer.

The National Hot Dog and Sausage Council, an industry group, says many other studies contradict those findings.
