Welcome back, Maytag Blue. We’ve missed you. Just in time for holiday cheese boards, this beloved Iowa product has returned to shops. It has been almost two years since Maytag Dairy Farms suspended production, in the aftermath of a positive test for Listeria in two lots of cheese. (No related illnesses were ever reported.) The road back has been longer and costlier than the owners imagined, but they managed to find a silver lining in this traumatic experience.
