An outbreak of E.coli O157 food poisoning in Glasgow and Lanarkshire, Scotland, has sparked an investigation by an outbreak control team set up by the departments of public health in cooperation with the South Lanarkshire Council and Glasgow City Council environmental health services.

Six cases have currently been confirmed in the outbreak, which is believed to have originated at a privately-catered christening function at the Tabernacle Masonic Hall, near Glasgow, on 9 September.

Dr Jim McMenamin, a consultant in public health medicine, told BBC news that he was optimistic all the cases had been identified: “Given the time delay since the event, we are hopeful that most cases have already been identified.

“Usually people affected by this bug develop symptoms within three to five days after eating infected food.”

The UK Food Standards Agency (FSA) established a task force last year to promote awareness and give advice on the potentially deadly bacterium.
