i looked it up online and chicken the sea whole oysters are gluten free https://www.amazon.com/Chicken-Whole-Oysters-Protein-Gluten/dp/B08W5BCVNF (listed here as gluten free on amazon) and the website lists their only products that aren't gluten free: https://chickenoftheseainternational.zendesk.com/hc/en-us/articles/1500004245202-Are-Chicken-of-the-Sea-products-gluten-free- . double check if there's any cross contamination but it doesn't list it anywhere as far as i can see
