Food scientists teach that smell is a great indicator of food safety. In a relationship too, it’s when something “smells off” that you know it may be reaching its expiry date

The younger, less rosy-eyed generation already understands that things other than death can pull two people apart much earlier. Representation pic
I have a tin of canned tuna in spring water in my fridge door. I bought several cans of the stuff around Christmas of 2017 when my son, normally resident in Canada, visited me. Back then, he had a thing about tuna melts with lots of Provolone cheese.
When he left for Canada, though, one tin remained unused. Five years later, it is still in exactly the same place in my fridge, uneaten and unlikely to be because I don’t really fancy tuna. But it’s nearing Christmas, people will be dropping by. Shall I serve them a nice salad with five-year-old tuna or would I be setting them up for food poisoning? What’s your advice?
