Lebanon Bologna is the well known American sausage which has its roots in the town of Lebanon, Pennsylvania, where it was made by German settlers. Lebanon Bologna is a semidry, fermented, heavily smoked, all-beef sausage which is not cooked. The traditional process (no starter cultures) calls for curing beef at 4-6 º C (40-43º F) for 10 days. |

| Instructions |
1. Curing. Grind beef with a large plate (3/4", 20 mm), mix with salt, Cure #2 and sugar and keep for 10 days at 4-6 º C (40-43º F).2. Grind cured beef through 1/8 - 3/16" (3-5 mm) plate 3. Mix ground meat with all ingredients. 4. Stuff sausage mix into 40-120 mm casings. Natural beef middles, collagen or fibrous casings. The larger casings are tied and stockinetted or laced with butcher twine for support as this is a large and heavy sausage. 5. Cold smoke for 4-8 days at < 22 º C, 72º F, 85% humidity.6. For a drier sausage: dry at 16-12 º C (60-54º F), 85-80% humidity7. Store sausages at 10-15 º C (50-59º F), 75% humidity.

| Notes |
Final pH: around 4.2-4.4, water activity 0.93-0.96, it is a moist sausage but extremely stable due to its low final pH. The sausage is often left for 3 days at 4-6 º C (40-43º F) for additional ripening. The sausage was traditionally cold smoked for 7 days in winter months and 4 days in the summer.

The sausage is often left for 3 days at 4-6 º C (40-43º F) for additional ripening.If no cold smoke is available, smoke with hot smoke for 6 hours. Start at 110 º F (43º C), then gradually increase temperature and smoke at 120º F (49º C) for 3-4 hours.

Traditionally made Lebanon Bologna is not cooked. To comply with increasingly tougher government regulations for preventing the growth of E. coli 0157:H7, most manufacturers subject this sausage to a heat treatment:
Lebanon Bologna - according to compliance guidelines for fermented products. Instructions are listed for the purpose of stressing the importance of the control of some of the pathogenic bacteria, in this case E.coli 0157:H7 which creates a safety hazard in products made with beef. This is how the commercial producer will make the sausage in order to be on the safe side.
Process to achieve a 7-log10 reduction of Salmonella and E.coli 0157:H7.
Ingredients: boneless lean beef - 10% fat
salt - 3.5%
potassium nitrate - 12 ppm
sodium nitrite - 200 ppm
Fermentation: 12 hrs at 80
º F, then at 100º F until pH of 4.7 or 5.2 is reachedHeat: 110
º F (44º C) for 20 hrs, OR115
º F (47º C) for 10 hrs, OR120
º F (49º C) for 3 hrs
