I was buying bacon and sausage from a local grower who sells from the Dallas, TX farmer's market. I never thought to look at the label, as he was selling it under the auspice of "all natural, locally raised, no antibiotics". I bought his products for three months, then one day looked at the label while I was cooking: sodium nitrite. All his bacon was cured. I stopped buying from him immediately and went with an all-natural, uncured producer.
