New York CNN  —  Chick-fil-A is telling customers to “please discard” Polynesian sauce dipping cups that were ordered over the past few weeks. “The Polynesian Sauce dipping cups may contain a different sauce that includes wheat and soy allergens,” Chick-fil-A said in a short note on its website. The cups were given out at its restaurants between February 14 and February 27. Customers can call the company at (866) 232-2040 with questions. Polynesian sauce is one of Chick-fil-A’s most popular dips, described on its website as a “sweet and sour sauce with a strong, tangy flavor.” It’s been on the chain’s menu for 40 years and has become so popular that it’s now sold in grocery stores. Chick-fil-A did not immediately respond to CNN’s request for comment.
