E. coli O157 – Update 24 Oct 2012
The Public Health Agency (PHA) and Environmental Health Officers from Belfast City Council are continuing to investigate an outbreak of Escherichia coli (E. coli) O157 linked to Flicks restaurant in Cityside Mall, 100-150 York Street, Belfast.
Dr Carolyn Harper, Director of Public Health, PHA, said: “The PHA has activated a full public health response to this outbreak and the situation is being managed and monitored very closely.
“We continue to meet daily with colleagues at Belfast City Council to share information and results and are working with the Council and Food Standards Agency to ensure this investigation progresses steadily. We are also liaising with the Health Protection Agency regarding typing and other specialist advice.
“This is a complex, evolving and detailed investigation and all aspects of the outbreak are being examined thoroughly. As such, it would not be appropriate to comment at this stage on any potential cause of the outbreak, but as with all outbreaks, a full report will be made publicly available when the investigation and analysis is complete.
“It is not always possible to identify a specific source in outbreaks as the mechanism of contamination of food may have been short term and corrected in subsequent cleaning, food hygiene practice, or normal disposal of food.
“What we can say at this stage is that the information to date suggests no wider risk to the public from E coli O157 as regards this outbreak, and the restaurant remains closed. However, it is important that everyone helps to prevent the spread of E. coli and washes their hands after using the toilet and before eating or preparing food. People with vomiting or diarrhoea should remain at home and not prepare food – this is good advice at all times, not just when there is an outbreak.”
There are various types of E.coli O157 and the PHA has confirmed that the type of E. coli O157 in cases in October is different from the type found in August cases associated with the same restaurant. These results are from a first phase of typing tests which showed the cases in August to be Type 8. The confirmed cases in October are Type 54.
The four cases of E. coli O157 in August which were linked to this restaurant were investigated thoroughly at the time. All tests on the restaurant were negative. In addition, further environmental health inspections were conducted, all of which were satisfactory, and enhanced surveillance to monitor for cases was also put in place. The current cases came to light through that enhanced monitoring.
Furthermore, there were no cases of E. coli associated with Flicks restaurant in the six week period between the end of August and 9 October.
When a possible case was notified on 9 October, PHA and Environmental Health Officers again responded immediately and took all necessary steps. This resulted in the voluntary closure of the restaurant; if the restaurant had not closed voluntarily, it would have been required to close.
As of 3pm on Wednesday 24 October 2012, there were 124 confirmed cases and 166 probable cases. The increase in confirmed cases over recent days is not unexpected and is as a result of probable cases becoming confirmed following testing. The number of probable cases is levelling off as fewer new reports are coming forward.
The management of Flicks are cooperating with the investigation.
The PHA has advised that anyone who ate at Flicks restaurant since 24 September and has symptoms of diarrhoea (especially bloody diarrhoea) and/or abdominal pain should contact their GP urgently for medical advice.
Dr Harper explained: “Escherichia coli bacteria are commonly found in the intestines of humans and animals. There are many different types of E. coli, and while some live in the intestine quite harmlessly, others may cause a variety of diseases. The bacterium is found in faeces and can survive in the environment.
“Symptoms caused by E. coli O157 can include diarrhoea, which can range from mild to profuse watery or bloody diarrhoea, tummy cramps, nausea or vomiting.”
