(WJW) — Chick-fil-A has announced it is changing the chicken it serves at all of its restaurants this spring.

The plan is to switch up the requirements for the kind of chicken purchased from the current No Antibiotics Ever (NAE) to No Antibiotics Important To Human Medicine (NAIHM).

“NAE means no antibiotics of any kind were used in raising the animal. NAIHM restricts the use of those antibiotics that are important to human medicine and commonly used to treat people, and allows use of animal antibiotics only if the animal and those around it were to become sick,” the restaurant said in a statement.

The company made clear that it continues to be dedicated to serving customers the highest quality food. An exact date for the change has not been announced.

In a statement to Reuters, Chick-fil-A explained it is making the move “due to challenges it foresees finding chicken supplies that ‘meets our rigid standards.'” This comes roughly a decade after Chick-fil-A committed to serving antibiotic-free chicken.

Chick-fil-A also introduced a new menu item it’s testing: pizza.

In mid-March, the Atlanta-based company rolled out six new pizza options at its test kitchen, Little Blue Menu, in College Park, Maryland.
