This answer would be temperature dependant and determined by the salad ingredient that would spoil the quickest. For tuna salad, I would think the tuna would spoil quickest. This is from Bumblebees website regarding canned or pouched seafood; "once cans or pouches are opened, any unused contents should be immediately refrigerated and utilized within one to two days"
If stored covered it will stay fresh about 5 days.
Fresh raw tuna should only be kept for a day, maybe two, in the fridge. If it turns out you're not going to use it in that time frame, freeze it.
Fresh seafood should be either eaten or frozen after two days.
i would not go past 2 days,mayo+fish=bad stomach ache if it gets too old or improperly stored!!
Tuna salad should be good in the refrigerator for three to four days.

The USDA says to throw it out after 2 months in the refrigerator

Royal pudding pies should stay fresh 3 - 4 days in the refrigerator if covered properly.
