is it bad to heat up salad that has mayo in it to make like a tuna melt? does that make the mayo go bad?

not really.... but no one puts mayo in a tuna melt anyways..... just tuna and either mozza or swiss cheese....

Home made mayo, which contains raw egg yolks, yes, is a danger for salmonella. But if the eggs are contaminated, they are contaminated and the salmonella is there. Most of us, however, don't make mayo at home.

Commercially produced mayo has so many preservatives in them that I wouldn't worry about it. It is the other ingredients that are often combined with mayo that cause many problems - like boiled eggs and tuna. Assuming that your tuna salad hasn't been sitting in the refrigerator for an unreasonable amount of time (would you still eat it cold?), then heat it up and eat it up, and don't put any of the cooked leftovers back in the refrigerator. Don't put the tuna melt in a bag and take it to work for lunch six hours after you've made it.

I personally wouldn't use mayo in a tuna melt, but that's a matter of taste. Mayo is an ingredient in MANY recipes that are cooked. It's a good ingredient, just use it in moderation, and handle anything that you cook properly so that you can eat safely and tastily!

I do not recommend you to heat up fruit salad that has mayo because it would destory the flavour of mix fruit. But tuna is ok, it won't go bad if you consume tuna+mayo salad with pasta, let's say, as hot dish! I mix tuna & mayo with lemon juice & black pepper then put the mixture on spaghetti, sprinkle cheese on top, bake it for about 10 minutes, garnish it with some chopped parsley. It is a quick & tasty dinner for me.

Mayo is made from oil and raw egg whites. Does it no harm at all to heat it but it can make you really sick if you leave it out very long.

I use mayo in tuna melts all the time. Works fine.

"REAL" mayo is made with raw egg-that is, the type you make yourself. Storebought mayo has been pasturized and will be safe to cook. The major concern about letting mayo get warm is because of the fat spoiling and the risk of botulism-if you're going to make the sandwich and consume it in a reasonable period of time-it won't spoil and you'll be fine. The tuna melt will taste great too.

It is fine to heat things with mayo in it, but I just wouldn't re-heat it. Many hot recipes call for mayo- especially dips.

Also- mayo in tuna salad is very common.

This is fine as long as you put it right in the fridge if you are saving it for leftovers. The mayo won't go bad just by being cooked -- it's when it sits out at room temperature, letting bacteria grow in it, that it can spoil and possibly make you sick.

If you eat it right away you'll be fine but if you warm it up and then let it sit you the mayo may go bad and you may get a stomach ache..

You can heat mayo., I have recipes that use it in cooked dishes.

no. the mayo will not go bad. it may separate, becoming oily but not go bad. it also may not taste that good. i suggest just eat it cold.
