We have been informed by Public Health England that there is an ongoing outbreak of listeriosis linked to smoked fish. Since 2020 there have been 12 cases (9 in England, 3 in Scotland) of listeriosis where the vehicle is believed to be smoked fish. While food chain investigations have not revealed any contamination that breaches the legal threshold for L. monocytogenes, it is important that high-risk patients are aware of the risks and are advised how to safely consume these products.
Patients who are pregnant or clinically vulnerable are advised to avoid smoked fish.
