ATLANTA, GA – People with an allergy to dairy products may want to steer clear of Chick-Fil-A for a while.

The Atlanta based fast food giant says some of its grilled chicken nuggets and filets contain a dairy allergen.

Restaurant officials say their supplier accidentally added the ingredient to the recipe, affected all of their locations nationwide.

And while the allergen may prove harmless to most diners, it does pose a threat to those with sensitivities to the allergen.

Chick-Fil-A says it’s doing all it can to prevent a similar mistake from happening again.
