Contains seed oil: per Sonic's own allergen documentation
Fryer shortening: vegetable oil confirmed to contain soy. Applies to both Tots and French Fries.
Shared fryer, shared cross-contact
Sonic's own allergen guidance notes the same fryer handles corn dogs (wheat batter), breaded chicken, and onion rings (milk), alongside Tots and Fries. That means potential cross-contact with other allergens beyond the seed-oil content of the shortening itself.
