DES MOINES, Iowa (AP) — Some beef processors are planning to label beef that contains the meat product commonly called "pink slime." The USDA says it has received applications for such labeling for the first time and plans on granting approval after it checks labels for accuracy. The USDA says the labeling is a voluntary initiative by companies who want to inform consumers. Some processors who provide the ammonia treated trimmings plan to identify ground beef containing the product with a label that says: "Contains Lean Finely Textured Beef" or a similar statement. Tyson Foods, which buys it and uses it in some products, says controversy surrounding the product has increased demand for beef without it. A spokesman says more people also have recently expressed interest in buying ground beef with the product in it.
