Three hospital patients have died in an outbreak of listeria linked to pre-packed sandwiches.
Public Health England (PHE) said the victims were among six patients affected in England and the deaths occurred in Manchester and Liverpool.
Two of the victims were at Manchester Royal Infirmary, with the other a patient at Aintree Hospital.
Sandwiches and salads from The Good Food Chain linked to the outbreak have been withdrawn and production stopped.
PHE said the products were withdrawn from hospitals when the links to the infections were first identified.
A spokesperson for the Manchester University NHS Foundation Trust said it offered its "deepest condolences to the bereaved families" and "sincerely regret" that two of their seriously ill patients contracted listeria.
The trust, which would not say when the deaths happened, said the sandwiches were from the patient menu.
The first patient showed symptoms on 25 April while the most recent case was reported on 15 May, a PHE spokeswoman said.
Aintree Hospital said: "Public health experts advised us of this supply chain issue on Friday 24 May and we immediately removed all products from this supplier."
