It seems that Hershey's 5TH AVENUE Candy Bars are not gluten-free as it is not part of the list of 147 gluten-free Hershey products.
A food bearing a gluten-free claim does not contain the protein from wheat, rye, barley, spelt, kamut, triticale, farina, vital gluten semolina, malt vinegar or protein derivatives of these foods, or, if such grain is present, the level of such gluten protein has been reduced to less than 20 parts per million.
According to The Hershey Company, the best way to determine if their products contain a gluten ingredient is to read the product label. The label includes an accurate, current listing of the ingredients in their products. Because, on occasion, the list of ingredients can change, they strongly encourage consumers to check the ingredient label on the package each time before they make a purchase.
