Listeria monocytogenes has been detected in a number of frozen vegetables tested in Ireland.
The Food Safety Authority of Ireland (FSAI) said findings show a potential risk of illness for consumers who have non-ready-to-eat (RTE) frozen vegetables, fruits or herbs without cooking.
After a 2015 to 2018 listeriosis outbreak in Europe traced to uncooked non-RTE frozen sweetcorn and other vegetables, a national microbiological survey on frozen vegetables, fruits and herbs sold in Ireland was done between August and November 2019 by the FSAI. More than 50 people were sick from five countries and 10 died in the outbreak linked to vegetables made by Greenyard in Hungary.
Of 906 samples tested for Listeria monocytogenes in Ireland, 27 were positive, and 21 were non-RTE frozen vegetables. It was detected in four samples of RTE frozen fruits and two RTE frozen vegetables.
