Freddie Starr has been forced to drop out of I'm A Celebrity ... Get Me Out Of Here! after being advised by medics, in case his illness flares up again.
The comic (68) had to be rushed to hospital after suffering what was thought to be an allergic reaction shortly after eating a foul meal of fermented egg and a camel toe.
Disappointed Starr said he felt "sick" not to complete his stint in the Australian jungle but had to respect the opinions of doctors.
"I wanted to be there until the very end but there's no use crying over spilt milk," he said.
Starr, who has had bypass surgery, was taken ill two hours after a stomach-churning challenge.
He had won the "greasy spoon" bushtucker trial after the determined comedian chomped through mice tails, a pig's anus and turkey testicles, while fellow contestant Mark Wright looked on aghast.
Doctors have not been able to pinpoint the exact cause of the apparent allergic reaction.
After being told he could not continue with the ITV1 show, Starr said: "I was sorry to hear the news about what the doctors said -- that I was allergic to something, to play it safe and best for me not to go back.
"ITV's got a duty of care and it's only right that the doctors advise them to keep me away from the jungle. It may not happen again but we'll never know.
"They checked me over and couldn't find anything wrong with me, but told the TV people it's a risk and that I could be allergic to something in there -- and that duty of care has to be respected."
A spokesman for the show said: "Freddie has been a terrific contestant. His bush tucker trial is one of the stand out moments in the history of the series and we wish him all the very best."
