Food Allergy Research and Education (FARE) reports that effective January 1, 2018, Wendy’s restaurants in the US have changed the procedure for applying ketchup during sandwich making. While the ketchup is being applied to the bun, the utensil comes into contact with mayonnaise which contains egg.
Products directly impacted by this change include Double Stack, Jr. Hamburger, Jr. Cheeseburger, Kid’s Hamburger, Kid’s Cheeseburger.
Customers with an egg allergy are encouraged to ask for their sandwich without ketchup due to this cross-contamination risk. They may ask for ketchup packets instead.
