Royal Caribbean Cruises wants its pork suppliers to detail their efforts to eliminate gestation crates used to confine pregnant pigs.

In 2012, the company that owns Royal Caribbean International, Celebrity Cruises and four other cruise brands, said it would support the pork industry’s efforts to eliminate the controversial cages from operation, setting 2022 as the target date by which to reach its goal.

As a next step, Royal Caribbean will request an update from its pork suppliers regarding the plans and progress of their respective pork producers in meeting the pork industry goal of moving away from gestation crates in their operations by 2022. The cruise company says it’s doing this to determine which producers share its objective of moving to a gestation-crate-free pork supply.

Also this week, Tyson Foods said it has asked its farmers to improve breeding pigs’ housing methods.

About 60 of the world’s largest pork buyers — including McDonald’s, Burger King, Costco, Oscar Mayer and others — have committed to eliminating the crates from their supply chains.

Pork providers Smithfield Foods and Hormel have pledged to end the use of gestation crates at their company-owned facilities by 2017.
