I try to avoid 'enhanced' products if at all possible. Usually meats are 'enhanced' by injecting with saline solution (salt water), or brine, which can include other spices as well. This does two things. 1st the salt acts as a preservative to improve shelf life, and 2nd, the solution adds weight to the product...arghhhhhh. I like to stick with fresh unenhanced products. Fresh by Dept. of Agriculture definition means just that. If a product is labeled as fresh, its just as it came off the hoof.
