Three deaths are being investigated as part of a listeria outbreak linked to desserts supplied to NHS hospitals and care homes.
The UK Health Security Agency (UKHSA) confirmed it is investigating the deaths as well as two non-fatal cases between May and December of last year.
One death was recorded as listeriosis. Two other people were known to be infected with listeria bacteria at the time of their death.
The bacteria was detected in a chocolate and vanilla mousse and a strawberry and vanilla mousse, both supplied by Cool Delight Desserts, UKHSA said - although they have not been confirmed as the source of the infections.
