Shake Shack shade comes after Chick-Fil-A's announcement about antibiotics in chicken

The announcement from Shake Shack comes on the heels of Chick-fil-A announcing last month its shift to allow some antibiotics in its chicken starting this spring, overturning a 2014 commitment to use only antibiotic-free chicken.

"To maintain supply of the high-quality chicken you expect from us, Chick-fil-A will shift from No Antibiotics Ever (NAE) to No Antibiotics Important To Human Medicine (NAIHM) starting in the Spring of 2024," Chick-fil-A's website says.

According to the announcement, chicken antibiotics will only be used "if the animal and those around it were to become sick." The antibiotics used to treat the poultry are not intended for humans.

"In accordance with FDA requirements, all antibiotics must be cleared from the chicken’s system before it is considered available for the chicken supply.  The United States Department of Agriculture audits and verifies that suppliers are meeting the requirements of the Chick-fil-A NAIHM commitment." the statement said.
