If I make a big batch of tuna fish...how long will it be good?

Answer 1

It will depend on how you have prepared it, what ingredients you have added to the tuna, what type of storage container you are using and the temperature at which you are storing it.

Typically 2-3 days max in an air tight container stored in the fridge if you add in chopped up veggies (carrots, celery, tomato, cucumber, etc).

If you are simply mixing tuna with mayo or another "dressing", then I'd say up to one week.
