(Hot)dog fight: Oscar Mayer in dustup with Ball Park

It's a dog-eat-dog world, especially when it comes to the frankfurter business.

Sara Lee Corp., maker of Ball Park hot dogs, has filed a lawsuit against Kraft Foods Inc., parent company of Oscar Mayer. The litigation skewers Oscar Mayer, disputing taste-test results in which Kraft claims its brand is top dog and claiming that Kraft shouldn't be allowed to label its franks as "100 percent pure beef" in light of the flavorings and nitrites in them.

The suit, filed in Illinois where both companies are based, wants Kraft to run "corrective" advertisements and pay Sara Lee damages.
