(AP) — Cargill Inc. says it will start labeling beef products that contain finely textured beef, an ingredient that came under attack as “pink slime.”

The meat company says the new packages will appear before next year’s grilling season and is in response to consumer demand. It says packages will note when a product “Contains Finely Textured Beef.”

Finely textured beef is made of fatty bits of meat left over from other cuts that are treated to kill bacteria. The filler had been used for decades in the U.S. but started to gain negative attention after a New York Times article in 2009, in which a federal microbiologist referred to it as “pink slime.”

Cargill says it has been making finely textured beef since 1993.
