Carnival Corporation, the world’s largest leisure travel company, announced on Tuesday that it will shift chicken purchasing policies across its nine leading cruise line brands.  By 2024, Carnival Corporation will require sourced chicken to be GAP-certified and produced under standards that require all chickens to be given more space and enhanced environments.

In addition, Carnival Corporation’s chicken suppliers will be required to process their products in a humane manner through a multi-step controlled-atmosphere system and demonstrate compliance with these standards, the company announced.

“Working with animal protection organizations, including the Humane Society of the United States, and the Humane League, Carnival Corporation is committed to aligning welfare standards for broiler chicken ensuring that 100 percent of chicken sourced will be certified by the Global Animal Partnership (GAP).

“Carnival Corporation and our brands recognize animal welfare is an important issue for our guests and the general public, as well as us, and by teaming up with leading organization that have made this commitment to responsible sourcing, we are optimistic that this will help advance broader adoption of these conscientious practices,” said Julia Brown, chief procurement officer for the Carnival Corporation.

In 2015, working with the Humane Society of the United States, Carnival Corporation committed to switching to 100 percent cage-free eggs across all its brands by 2025.
