The NHS in Derby has offered its condolences to the family of a person who died after contracting listeria.
The University Hospitals of Derby and Burton Foundation Trust have confirmed that one of five people who died after contracting listeria was diagnosed and treated at the Royal Derby Hospital.
The Trust said they will continue to work with the national authorities while the investigation takes place.
On Monday, the Health Secretary Matt Hancock confirmed cases of listeria at the Leicester Royal Infirmary and the Royal Derby Hospital.
Listeria is a bug that can cause an illness like the flu.
They're two of seven hospitals the NHS has identified where cases of listeria have been found linked to contaminated sandwiches from a single supplier, which have resulted in five deaths.
It relates to products supplied by manufacturer The Good Food Chain, which is based in Stone in Staffordshire. The company says it's withdrawn other products linked to the cases, and has voluntarily ceased production. As has the business that supplied them with the infected meat.
Matt Hancock said the risk to the public is very low and has promised a "full and thorough investigation" with "severe consequences" if there's any evidence of wrongdoing.
