A woman who contracted food poisoning at a First Communion function died due to salmonella, an inquest has heard.
Investigations into the outbreak are continuing, an inquest into the death of 55-year-old mother of one Sandra O'Brien heard.
Ms O'Brien, from Rivervalley, Swords, Co Dublin died on 21 May, 2017 following the consumption of food prepared at O'Dwyer’s Bar and Grill, Strand Road, Portmarnock, Co Dublin.
Ms O’Brien’s husband, Garda Sgt Michael O'Brien, attended a short inquest hearing into her death at Dublin Coroner's Court.
Investigations by two separate authorities are ongoing into the salmonella outbreak, the inquest heard.
The Health Service Executive's Environmental Health Office and the Food Safety Authority of Ireland are preparing files on the incident.
Reports will be filed by both authorities to the Director of Public Prosecution once investigations are complete.
"It's an investigation into the outbreak in relation to compliance with food safety legislation. We are not investigating the death of a particular person," Mr Noel Donnelly, Principal Environmental Health Officer for Fingal, told the court.
The inquest heard that the cause of death was acute myocarditis as a consequence of salmonella infection, with previous myocarditis as a contributory factor.
Myocarditis is inflammation of the heart muscle and can be caused by a viral infection or an immune response, reducing the heart's ability to pump and causing rapid or abnormal heart rhythms.
After the incident the HSE said it became aware of more than 50 people from a number of different family groups supplied by the same company over the weekend of 13 and 14 May last year, who became ill.
The catering company, Flanreil Food Services, who provided the food served on the day of the First Communion function was represented at the inquest by solicitor Elaine Byrne.
Inspector Oliver Woods applied for a six-month adjournment of the inquest to allow for investigations to continue and the coroner adjourned the inquest until 8 November, 2018.
"If there are any updates in the meantime we will inform you," Insp Woods told the court.
Coroner Dr Myra Cullinane extended her condolences to Mr O'Brien.
