The packaging should tell you whether or not it should be refrigerated. Smoked meats come in a variety of forms. Some require refrigeration for safety, others use it to prolong keeping qualities.
You DON'T need meat, anyone who tells you otherwise is very ignorant, talking about what they don't understand. From meat, you can get protein, something which you need in your diet, but eating meat...
If unopened then most likely not unless stated otherwise on the packaging, but if opened then yes, refrigeration for any opened poultry/seafood is a must/good practice.
