Thank you for your email. Our Burgers and Steaks do not contain any of the items you mentioned. (peanut, tree nut, sesame) However our Mama Lucia, Gina Lina and Prima Familia Meatballs do contain sesame seeds. Please understand that the products that contain sesame seeds and the products that don't are produced in two separate buildings.
Quaker Maid Meats, Inc. produces our products in a modern, state of the art food processing plant. We feel our allergen control is stringent enough that cross contamination would be extremely unlikely; however human error is always possible. Given that possibility, however remote, we believe we would not be a responsible company if we were to make any type of absolute guarantee.
I hope this answers your question.
Sincerely Renee Miller Customer Service Specialist Quaker Maid Meats Inc.
