The Food Standards Agency has said it is investigating an outbreak of listeria at a smoked salmon supplier, but stressed no consumers had to date fallen ill as a result of the incident.

The Fine Seafood Company last week recalled all date codes of its whiskey-cured, oak-smoked salmon line after high levels of listeria monocytogenes were detected. The recall involved a total of 444 individual packs.

“Corrective actions have been put in place to avoid re-occurrence,” a spokesman for the FSA said.

No other products made by The Fine Seafood Co - which did not respond to requests for comment - were affected.
