Wendy’s® is testing a New Grilled Chicken Sandwich that affects people with milk and sesame allergies.

The new chicken sandwich has sauce that contains milk (besides the original egg). It comes on a multigrain bun containing:

• sesame seed
• flax seed
• quinoa

The sandwich is available in seven areas around the U.S.:

• Pittsburgh
• Las Vegas
• Jacksonville
• Orlando
• Gainesville
• Kansas City
• Austin

The original chicken sandwich contains egg and soy in the sauce, and a wheat bun. The original sandwich is still available nationwide, except for the seven test markets.

The New Grilled Chicken Sandwich contains egg, milk, sesame and wheat.

The multigrain bun shares a toaster with the company’s premium sandwich buns. Wendy’s said to ask for untoasted sandwich buns if you have concerns about cross contact with the multigrain bun.

Cooking foods with the same equipment may cause cross-contact of allergens. Even a tiny amount of an allergen may cause a reaction. Learn how to prevent cross-contact in your own kitchen.
