Pensioner Neville Turner got a nasty shock when he bit into a "boneless" fillet of cod.
As he tucked into his favourite meal of battered fish, croquette potatoes and peas, he gagged when an inch-long bone became wedged in his gullet.
Neville, 78, who suffers from a sensitive throat condition and has undergone a triple heart bypass, was very distressed when he felt something "dig into" the flesh at the back of his throat.
He said: "I was eating my meal as usual when suddenly I felt something sharp.
"Suddenly, I gagged and felt something dig in. I managed to get my fingers in my gullet and pull it out.
"When I saw it I could not believe how large it was. It is at least an inch long with a sharp point."
Neville is due to attend a garden party at Buckingham Palace in June for his services to the community – he has been a stalwart of New Parks Club for Young People for more than four decades.
He said: "There was a point when I was choking I thought I would not be making that appointment. I felt sick and dizzy.
"I was lucky enough to be able to pull it out and have my daughter on hand to help me."
Daughter Janice Wesson said the fish was the last in a pack of four "chunky, boneless and skinless" battered fillets she had bought from Morrisons.
She said: "Dad loves his fish but, because of his throat condition, it has to be easy to eat.
"That is why we opt for boneless and skinless fillets. We have never had any problems with this product before.
"I have never seen a fishbone like it. It was very upsetting. Dad was badly shaken by the experience."
The incident happened on Tuesday lunchtime and they rang Morrisons, who said they would send them an envelope which they asked them to send the bone back in.
The company has said it will analyse the bone and get back to the family once the results are known.
A Morrisons spokesperson said: "We take product quality very seriously. Although every care is taken to remove bones in our fish fillet products, on rare occasions some may remain.
"This is carefully highlighted on our product labelling."
"We have apologised to Mr Turner for any distress this may have caused, and will return to him post-analysis of his product."
