Seasoned or flavored products not listed may contain Hydrolyzed Vegetable Protein (often derived from wheat). The above products do not contain gluten; however, they are produced on the same line as our products that do contain gluten. The lines are washed between batches; however a slight residue may remain on the line. Individuals who are extremely sensitive may be affected." Check it out Jerry
