That's the label that a vegan advocacy group wants a New Jersey court to order Oscar Mayer, Hebrew National and other food companies to slap on hot dog packages. The nonprofit Cancer Project filed a lawsuit Wednesday on behalf of three New Jersey plaintiffs asking Essex County superior court to compel the companies to place cancer-risk warning labels on hot dog packages sold in New Jersey. 'Just as tobacco causes lung cancer, processed meats are linked to colon cancer,' says Neal Barnard, president of the Cancer Project and an adjunct professor at the George Washington University medical school in Washington , D.C. 'Companies that sell hot dogs are well aware of the danger, and their customers deserve the same information.' The defendants in the lawsuit, which seeks class-action status, include Nathan's Famous Inc., Oscar Mayer owner Kraft Foods Inc., Sara Lee Corp., Marathon Enterprises Inc. and ConAgra Foods Inc., which owns Hebrew National. Efforts to put warning labels on hot dog packages are 'crazy,' said Josh Urdang, 27, as he stood in line to purchase two franks at Pinks Hot Dogs in Los Angeles on Tuesday. 'It wouldn't change how many hot dogs I eat. Not at all.' His friend Joe Di Lauro, 31, called such a move 'overpolicing.' 'At what point do you stop breaking things down?' Di Lauro said. 'Unless we're going to put a warning label on every single food and say what's bad in it.' Other consumers were skeptical of the Cancer Project's agenda. 'Vegans complaining about hot dogs is like the Amish complaining about gas prices,' said Susan Thatcher of Irvine, Calif. In 2008, Americans spent $3.4 billion purchasing 730 million packages of hot dogs and sausages in U.S. supermarkets, according to the National Hot Dog & Sausage Council. Nutrition experts say that the science is complicated and that slapping warning labels on the staple of baseball games and picnics would not have much effect on public health. 'If one were to call for a `black label' on frankfurters, where should the warning label end? If we were to evaluate each food for its naturally occurring toxins and eliminate that food, then our food plate would be empty,' said Roger Clemens, a nutrition expert at the University of Southern California pharmacy school. The industry is against such warning labels. 'These proposals are unfounded. Hot dogs have been enjoyed by consumers for more than 100 years,' said Sydney Lindner, a Kraft spokeswoman. The Cancer Project is a branch of the Physicians Committee for Responsible Medicine, a group that lobbies against animal research and advocates for the adoption of meat-free diets. In the lawsuit, the Cancer Project cites the role of nitrites, a preservative used in cured and processed meats such as hot dogs, in the development of cancer-forming agents. During digestion, it breaks down into nitrosamines and other N-nitroso compounds that are considered carcinogens. Although some medical studies link red and processed meats to cancer risk, it's not clear whether it is because of the nitrites or other factors such as high fat content. 'There is speculation that nitrosamines can increase cancer risk when consumed in large amounts and frequently. Occasionally should cause no worry. The stuff people typically have with a hot dog may be a more immediate concern: too many calories from all the fat-laden potato and macaroni salads, sugary drinks and sweet desserts,' said Keith-Thomas Ayoob, a nutritionist at the Albert Einstein College of Medicine in New York. An American Institute for Cancer Research report cited in the lawsuit notes that one 50-gram serving of processed meat -- about the amount in one hot dog -- consumed daily increases the risk of colorectal cancer, on average, by 21 percent. Colorectal cancer kills about 50,000 Americans annually. But a 2004 analysis by Harvard University researchers of pooled data from 14 studies in North America and Europe could not find a similar link between various red and processed meats and cancer. But they did find that higher consumption of poultry and fish may be associated with a lower risk of colorectal cancer. The lawsuit acknowledges debate over how the consumption of some types of meats leads to greater cancer risk but argues that that doesn't negate the need for hot dog warnings. 'This situation is similar to the link between the smoking of tobacco products and lung cancer: While all the molecular events linking the smoking of tobacco to the development of lung cancer are not known, the link cannot be disputed,' the lawsuit states. There may be arguments for broader health warnings about red meat consumption, but the bigger risk is from heart disease rather than cancer, says Michael Jacobson, executive director of the Center for Science in the Public Interest. 'Though I favor warning notices in certain circumstances, the overuse of warnings can lead to `warning fatigue,'' Jacobson said. 'Eating hot dogs occasionally is not by itself worrisome.'
