Pregnant women and pensioners are being warned to avoid "ready-to-eat" foods, such as raw smoked salmon, without cooking it first after the latest listeria outbreak.
Fourteen people have fallen ill with Listeria monocytogenes since 2020, eight of these cases were found this year. The infection can cause a woman to miscarry and can be fatal for vulnerable people.
The majority of cases are in England and Scotland and one person was pregnant. Most people reported they had eaten fish before contracting the infection and falling ill.
