I shop at Smith's which is a Kroger brand store and buy their ground meats all the time and have never had a problem with any of them. A natural solution shouldn't have gluten in it, I would eat it without worry. They certainly won't be getting back to you on a weekend.
Thanks, Adalaide. In case you or anyone else is wondering, here is the response I got back from Kroger:
Thank you for contacting Customer Connect. My name is Chris and I received your email regarding our Reduced Fat Ground Pork. While this product has no gluten containing ingredients, we cannot guarantee any food to be truly 'gluten free' as we do not have dedicated manufacturing facilities or product lines for gluten free foods. These facilities are thoroughly cleaned, however, between the production of differing products. We do have a wide array of products that are made with no gluten containing ingredients.
The pork is injected with 12% Sodium Phosphate solution that acts as a moisturizer and dissipates to less than 2% when cooked. It is added in order to enhance the meat’s texture and flavor.
I hope that you find this information helpful. If I can be of further assistance, please simply respond to this email or call 1-800-576-4377.
