Wegmans, an upscale grocer headquartered in Rochester, N.Y., is offering two new products specifically identified as nitrate-free, and nitrite-free and low-sodium uncured bacon made from antibiotic-free pork. The Applewood Smoked Bacon private-label line would normally have qualified for Wegmans’ “Food You Feel Good About,” the retailer decided that despite the 38 percent reduction in sodium, consumers see bacon as “flavorful fat” and the designation might have undermined the equity of the label.
