Such restaurants remain a possible link between a large number of the cases, although other possibilities continue to be investigated and no single source of infection has yet been identified. Neither of the two additional people infected in Lothian needed hospital treatment and both have now fully recovered from their infection.
An outbreak of Salmonella enteriditis phage type 5c was confirmed by the Food Standards Agency Scotland on 8 August. An Outbreak Control Team was set up by the Agency to investigate and take action to protect public health. Thirty-three cases were confirmed at the time. All those infected had become ill prior to or on 24 July. A further two cases were confirmed in Shetland on 23 August. Two more cases have now been identified in Lothian, bringing the total number to 37. However, there is a possibility that one of the new cases acquired the infection abroad.
