Fast food restaurant chain Chick-fil-A has started offering No Antibiotics Ever (NAE) chicken across its all restaurants across the US.

This move is in line with the company’s commitment, made during 2014, to serve NAE chicken nationwide by the end of 2019.

As part of the NAE commitment, the chicken within the restaurant chain’s supply is now being raised without administering any antibiotics, starting from the egg.

The US Department of Agriculture audits and verifies that the suppliers of the restaurant chain are complying with the requirements of the NAE commitment.

Chick-fil-A menu and packaging director Matt Abercrombie said: “We know consumers care about how their food is made and where it comes from, including the use of antibiotics. Because it was important to our customers, it was important to us.

“Chick-fil-A has always been committed to serving customers delicious food made with high quality ingredients and offering No Antibiotics Ever chicken was the next step. Our goal was to pursue the highest standard and partner with the USDA to verify it.

“As leaders in the chicken industry, we felt that if anyone was going to commit to No Antibiotics Ever, it should be us.”

Chick-fil-A said that it made a significant investment in its suppliers to achieve the NAE chicken commitment.

In addition, the fast-food chain is planning to reflect this achievement on the packaging across its restaurants starting this October.

Abercrombie added: “We worked with our suppliers to convert our chicken supply to No Antibiotics Ever, which was an industry-changing move, as the supply of No Antibiotics Ever chicken previously did not exist to match our scale.”

Based in Atlanta, Georgia, Chick-fil-A currently operates more than 2,400 restaurants in 47 states and Washington, DC.

In November last year, Chick-fil-A started offering delivery services from more than 1,100 of its restaurants across the US through DoorDash.
