While this might be true in some places (although I highly doubt it), it is most certainly not the case in the United States or Canada. Gluten in prepared meat is extremely rare. In the US, if wheat is present, no matter how small the quantity, it must be clearly disclosed on the label.
Hi, I found this post when searching on Google and I am erring on the side that it probably DOES contain gluten until I find some concrete proof otherwise. I found out last year when we began the gluten-free/CF diet for our 2 1/2 year old son (with Autism) via several local butchers that most pre=packaged meats are injected with a water and gluten substance. Why, I have no idea. This is why all sliced meats are unsafe to eat for people wishing to avoid Gluten, that is unless you purchase the pre-packaged sliced meats which clearly state on the label "Gluten Free".
