why do claussen pickles have to be refrigerated before opening but other pickles don't?

Answer 1

Pickles typically come in two varieties: refrigerated and non-refrigerated. Claussen pickles are always made fresh; therefore, they must always be refrigerated. In fact, Claussen is made all year round, by harvesting cucumbers wherever they are in season. Claussen is never cooked and always kept cold, so every bite brings a crisp crunch. Claussen offers a bold, sensory experience through its intense pickle flavor, crunch, cold freshness, and cucumber appearance.

Answer 2

So does that mean you could pick up bacteria like e-coli from unheated raw product like the whole spinach thing.
