Frozen corn and possibly other frozen vegetables are the likely source of an outbreak of Listeria monocytogenes in the UK and across Europe.

It is essential that defrosted frozen sweetcorn or vegetables are not eaten without cooking (ie. do not add to salads or sandwiches unless cooked first).

As of  June 2018, 47 cases including nine deaths have been reported.

Frozen sweetcorn is the likely source of an ongoing outbreak of listeriosis affecting five European countries including the United Kingdom.

Listeriosis is a rare but serious foodborne illness caused by the bacterium Listeria monocytogenes that can be more serious for those individuals who have weakened immune systems and also the elderly, pregnant women and infants.

The Food Standards Agency, Food Standards Scotland, Public Health England and Health Protection Scotland are reminding people that most frozen vegetables, including sweetcorn, need to be cooked before eating. This includes if adding them to salads, smoothies or dips.
