DENVER (AP) — Unionized grocery store workers in Colorado and Wyoming have approved a two-year contract extension.

The United Food and Commercial Workers Union Local 7 represents 15,000 workers in the two states. It says the two-year deal, announced Wednesday, will allow its members to keep quality health care benefits through 2015.

President Kim Cordova said the grocery stores agreed to pay another $11 million to cover health care.

The contract covers workers at King Soopers, Safeway, Albertson's, Smith Foods and City Market stores.
