A woman who contracted Listeria after being served an infected sandwich while in hospital says she believes she's lucky to be alive.
Tanya Marston has Crohn's Disease, and was being treated at a hospital in Kent. However she was served a sandwich with ingredients from a company in Salford, the source of a Listeria bug that's claimed three lives.
Ms Marston said she was on intravenous therapy with seven different anti-biotics, one of which was to protect her brain from meningitis.
She has received a letter of apology from the hospital and Public Health England says that it has taken action to contain the outbreak and that the risk to the public is low.
Two of the patients died at Manchester Royal Infirmary. The third death happened at Aintree University Hospital NHS Foundation Trust.
In total, six hospital patients who were seriously ill contracted listeria from the sandwiches.
The Good Food Chain, which is based in Staffordshire and produced the sandwiches, has voluntarily ceased production while an investigation is underway.
Meat for their products had been produced by North Country Cooked Meats, based in Salford, Greater Manchester, who have also ceased production.
A spokesman for the company said it "is currently co-operating fully with the environmental health and the Food Standards Agency in their investigations, and a further statement will be issued in due course."
It's now emerged that the public and patients were kept in the dark about the risk for two weeks.
Public Health England sent a letter to all relevant NHS trusts advising them not to serve any of the company's sandwiches to "patients in vulnerable groups" on the 26th May.
However the public weren't notified until Friday 7th June.
Health bosses say a multi-agency investigation confirmed the match of the type of listeria in the patients and the source late last Wednesday.
