Hilton Worldwide is planning to transition into using cage-free eggs and crate-free pork at its hotels, the company announced on April 6.

All hotels in the Hilton Hotels & Resorts, Waldorf Astoria Hotels & Resorts, Conrad Hotels & Resorts, Canopy by Hilton and DoubleTree by Hilton brands will be required to switch all egg usage to cage-free by December 31, 2017.

The company will also require that all pork products must be purchased from suppliers that house breeding pigs in groups rather than using gestation crates by December 31, 2018. These changes will initially apply in 19 countries where products are currently available and will be adopted in additional markets as supply comes online.

These actions are part of the hotel company’s global responsible sourcing strategy, which includes a focus on animal welfare.

“We are committed to addressing key issues throughout our business and supply chain and responsibly serving our guests and communities in a range of areas,” added Jennifer Silberman, vice president, corporate responsibility for Hilton Worldwide. “With more than 2,000 restaurants in our global footprint, our goal is to have a considerable impact on sustainable sourcing in our industry as well as drive humane treatment of animals throughout our supply chain.”

Hilton’s new animal welfare initiatives involving eggs and pork were announced in conjunction with the Humane Society of the United States (HSUS). Less than one week earlier, Dunkin’ Donuts made a similar announcement with HSUS.
