How long can a sandwich with mayo on it last in the fridge?

Answer 1

If the mayonnaise is unopened it should last about a year, in or out of the fridge. Once you open it you should store it in the fridge. Mayonnaise usually contains vinegar, which helps to preserve it but you should probably finish it before two or three months.

It helps a lot if you do NOT introduce bacteria into the opened jar. So use a clean spoon, and don't lick and stick your fingers in!

Answer 2

Answer:It's on the jar, but is not real helpful. It depends on your fridge temperature. Put a thermometer in your fridge and keep the temp at 33 degress. Everything will last longer.

Answer 3

Without refrigeration: no more than a couple hours.

With refrigeration: should be consumed the day it is made - the mayo will eventually get absorbed into the bread and make it very soggy.

Answer 4

A couple minutes if my kid is around...

Mayonnaise is not likely to be what gives you the food poisoning. It is common to see it left out at room temperature in some countries. It is the fish that will feed the bacteria and make you sick. If it is a hot day, you may find yourself with a case of food poisoning after eating a tuna sandwich that has been sitting out warm for an hour.

Answer 5

A sandwich with mayo can last a long time. Since I was five, I carried lunch in a Karo Syrup bucket, later a kraft brown bag, and left it in my saddle bag, or locker, or in the car for many hours (even days). The sandwich was always there; nothing happened to the sandwich and I eventually ate it. Of course, sometimes the bologna curled, the chicken dried out (wrapped in wax paper), the garden leaf lettuce always withered and got a little slick, but the mayo . . . the mayo never seemed to change. I am past eighty and have been told for nearly eight decades that I will die of food poisoning. Perhaps.

We dassn't throw food away. We ate it. Maybe, we are already poison. They say Grandpa was riding our pasture along the Scottsbluffs, a big rattler bit him and the poor thing died. I didn't know Old man Strickland but if they had mayo in his day, my guess he probably didn't cold-store his sanny either.

Answer 6

It should last at least a day I make them the night before put them in the fridge then take them to school the next day and it's all fine!!

Answer 7

Foods containing mayonnaise should be good for 3 - 5 days if stored in the refrigerator.
