U.S. Department of Agriculture may change guidelines for labeling “natural” chicken due to an ongoing dispute over whether or not poultry injected with salt, water or other ingredients could carry the label.

Currently, chicken is labeled “natural” if it does not contain artificial flavors or preservatives.

About one-third of chicken sold in the U.S. is injected with additives according to health advocates. They noted that the additives in “natural” chicken could represent up to 15 percent of the meat’s weight and double or triple its sodium content.

The agency agreed to review its policy after the critics argued that the additives in chicken might mislead consumers or harm those who need to limit their daily sodium intake, says AP writer Juliana Barbassa.

One of the strong supporters for the change is Perdue chicken, a third largest poultry producer in the U.S.

"Our labels say natural or all natural only if there is nothing added," company spokesman Luis Luna told Barbassa on Friday. "Under no circumstances is it acceptable to label poultry that has been enhanced with water or broth or solutions as natural, or all natural."

Perdue has joined the Truthful Labeling Coalition (TCL) to push the USDA to ensure that only 100 percent natural chicken without any additives is allowed to carry the “Natural” label.

Also, TLC wants the agency to force producers to identify all added ingredients in bold typeface with stricter enforcement of the USDA’s “Raised Without Antibiotics” label.
