Grandmother-of-four Julie Hemmings, 53, tucked in to a carvery meal in a London pub with her husband Mark, 55, brother-in-law Nick Kyriacou, and his wife Trish before the couple flew to Turkey.
But when the pair arrived at the resort the next day, Mrs Hemmings started spewing up ‘red’ vomit and died two weeks later after her condition worsened.
Doctors told her devastated husband that the poison was ‘seeping through her body’ after her bowel had perforated.
An investigation is now under way into the food poisoning claim after the couple and Mr Kyriacou all fell ill with sickness and diarrhea following their meal out.
A Merton Council spokesperson said: ‘Merton Council’s Environmental Health team are carrying out an investigation.
