As far as we could confirm, the ingredient labeling did not show any of the specified allergens such as wheat, egg, milk, buckwheat, or peanuts. However, neither source included a dedicated allergen-labeling field itself, so whether the food information label even has an allergen field is Not confirmed. Note that beef and beef tongue are not among the 28 specified allergen items required to be labeled under the Food Labeling Act.
