Possibly over-reacting here, but anyway.
Had beans on toast for tea. First bite I noticed a metallic taste, but put it down to ongoing issues after Covid last year.
Second and third bites, still metallic. Asked DS if his tasted weird and he said yes. Asked DH to taste. He said yes. I asked if the can was dented. He went to check and it wasn't but did smell very metallic and is slightly dull inside, but not rusty as such.
Stopped eating and started Googling, which helpfully suggested botulism could ensue from spoiled canned food.
Am now shitting myself (not literally).
