Mireille, Waterloo Quebec. --- Yes, It is GF. I have checked with the company directly and have used this product for years with no adverse effects. JoAnn --- It's gf. The only ingredients are spices. Diane --- Hi Jeff- Yes- Old Bay is gluten free. However, I did some research about this last summer during crab season here in Maryland, and you have to find out what else is used in the boil. It is not uncommon in the Chesapeake Bay area to used vinegar or even beer in the water used to steam or boil the crabs. Apparently, most commercial crab places don't use these, but typically people who steam crabs at home often use beer, since they are ususally drinking it when preparing the crabs! Hope this helps. -Joany --- i checked about a year ago and old bay was gluten free. the company is owned by McCormick which is great at labeling! their owner has allergies and so they are very aware of allergens and also gluten. cannot find the phone number right at this moment one thing to watch for with prepared crabs is if they add beer to the water Andrea Howe Chairperson WACSSG --- Last summer it was GF, although I have not checked on its status this year with McCormick. Esme in Maryland --- As a Marylander transplanted to Northern New England, I miss my crabs. You needn't have worried about Old Bay. The list of ingredients are: celery salt (salt, celery seed), spices (including mustard, red pepper, black pepper, bay (laurel) leaves, cloves, allspice (pimento), ginger, mace, cardamom, cinnamon), and paprika. I have used it for years and haven't noticed any problems. No gluten containing ingredients appear to be on the above list. Good Luck.
