No new cases of E coli O157 related to the Paisley outbreak have been identified. As the upper incubation period for this infection is 10 days and the cold cooked meat which appeared to be the source of the infection was removed from sale on the 13th August, the Outbreak Control Team do not expect any new primary* cases linked with this outbreak.
The total number of confirmed cases remains at nine and all of these cases have been linked to the Morrison’s store at Falside Road in Paisley.
The condition of a 72 year-old man at the Victoria Infirmary is stable and showing signs of improvement and a 70 year-old Paisley woman remains stable in hospital in the Republic of Ireland. The other six individuals affected are recovering at home.
All of the confirmed cases are either linked to the possible consumption of cold cooked meat during a short period from the end of July to the beginning of August 2007 or have resulted from secondary infection.
The Outbreak Control Team have concluded that it is not possible to determine the exact cause of the outbreak however all confirmed cases can be linked to cold cooked meat from the store’s delicatessen counter. No other common link between all the confirmed cases has been identified.
Dr Syed Ahmed, said: “Although it is not possible to pin point the exact cause of this outbreak, investigations are continuing. All confirmed cases can be linked to the purchase of cold meat from the Falside Road store’s delicatessen counter. Possible causes of the outbreak could include either contamination of meat at the store by a food handler or contamination of a single meat product before it was delivered to the store.”
A joint investigation by the police and Environmental Health Officers is also continuing. Officers from Environmental Health Services, Renfrewshire Council will work with Morrisons to agree procedures to allow the lifting of the voluntary restrictions in place on the deli at Falside.
Primary cases are those who became infected as a direct result of consumption of suspected contaminated meat. Secondary cases can become ill as a result of cross-infection from a primary case.
