She was with her husband Stewart and their two young sons when she suffered severe food poisoning after contracting the E-coli bug.
The 37-year-old, from Harpenden, Herts, was taken to hospital on Corfu on August 13 last year and was bleeding copiously, Westminster Coroner’s Court heard.
Mr Rawnsley told the inquest they were eating together in one of the hotel’s restaurants. Natalie ate chicken, salad, prawns and vegetables while he and his sons had pasta, bread and sausages.
He said: “As Natalie cut the chicken it oozed red blood at which point I commented it looked bloody. “She got up, took it back, replaced the chicken with a different piece and came back and ate it.”
Mr Rawnsley said his wife later complained of feeling unwell and he was woken at 3am when she began vomiting. He added: “The doctor came at 7am. After he diagnosed gastroenteritis he told us to separate to stop me and the kids catching it.
“I took the kids for breakfast. At 11am I came back to check on her. She was still being sick and asked me to go back to the doctors.”
Mrs Rawnsley was then moved to a hospital, on the other side of the island. Mr Rawnsley said: “At 11pm the doctor knocked on my door and said I must come to the hospital quickly. I thought my wife was going to be home in the morning.”
Her brother and niece also arrived at the hospital where she lay unconscious. She died a short while later.
Infections expert Professor Sebastien Lucas told the inquest: “Assuming it is an E-Coli infection, there’s a tipping point when it starts producing DIC [disseminated intravascular coagulation, where blood clots develop in the bloodstream].
“Once it starts doing that, you are doomed. The chronology I heard from Mr Rawnsley fits with that view.”
The inquest heard the chance of contracting it depended on genes – some people are more susceptible to it than others.
Dr Athanasia Vargiamidou, who performed the post-mortem examination said: “The blood was not able to clot properly.”
Assistant Coroner Dr Shirley Radcliffe recorded a verdict of death by the accidental consumption of E-Coli infected chicken.
