What is Bologna?

Before getting into details about the shelf life of bologna, let’s take a closer look at what bologna is.

Aside from the ground meat, the manufacturers typically add seasonings such as salt, pepper, and species to enhance sausage flavors.
They also add a curing agent that includes sodium nitrite to lengthen the shelf life of deli meats, lessen the chances of mold and prevent food poisoning.
Occasionally, you might find that the store-bought bologna deli meat comes with a red string similar to the casing of a hot dog. What exactly is that stuff? Can you eat it?
