Six cases of food poisoning relating to duck eggs have been confirmed in Ireland in recent months.
The Food Safety Authority of Ireland said it was investigating an ongoing outbreak of Salmonella Typhimurium DT8 linked to the consumption of duck eggs.
It said it was seeking further information in relation to the potential source of the eggs.
The food-poisoning danger is removed by thorough cooking and by preventing cross-contamination between any raw egg and ready-to-eat foods.
The authority advised consumers to only consume duck eggs that have been thoroughly cooked and to cease using raw duck eggs in any dishes that will not be cooked prior to eating.
It also recommended good hygiene practices, such as washing hands and preparation surfaces after handling or using duck eggs.
Symptoms of Salmonella Typhimurium DT8 infection can include diarrhoea, stomach cramps, vomiting and fever.
The authority said anyone who may have such symptoms and suspect it may be the result of duck eggs should contact their doctor for advice.
“The FSAI is working closely with the Department of Agriculture, Fisheries and Food, the Health Service Executive; and various local authorities to control this outbreak and to prevent further cases,” a statement said.
