Fast-food chain Chick-fil-A has sparked a social media backlash after announcing that it will soon allow certain antibiotics in the chickens it raises, citing supply issues.

Chick-fil-A restaurants in the U.S., Canada and Puerto Rico will transition “from chicken raised with No Antibiotics Ever (NAE) to chicken raised with No Antibiotics Important to Human Medicine (NAIHM), starting in the spring of 2024,” the company said in a statement posted on its website this week.
