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. It is too early to draw definitive conclusions at this stage.
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 Friday 19 October 2012, there were 44 confirmed cases and 144 probable cases.
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.
"It is vital that everyone follows some simple rules to prevent the spread of E. coli – not just those with symptoms, but everyone should wash their hands after using the toilet and before eating or preparing food. Raw and cooked food should be kept completely separate, raw meat should be cooked through and vegetables and fruit should be washed thoroughly before eating."
Investigations are continuing and final conclusions will emerge when all cases have been identified and analysed to identify any common links.
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.”

Examples of previous major E. coli outbreaks elsewhere in the UK:
During August and September 2009 there was an outbreak of E. coli O157 among visitors to Godstone Farm in Surrey, England. 93 people were affected.
In September 2005 there was an outbreak of E. coli O157 in Wales, with more than 150 cases, most of whom were children.
In 1996, there was an E. coli O157 outbreak linked to a butcher’s in Lanarkshire, Scotland, which resulted in over 300 cases.
