Four more cases of E coli have been linked to the SSE Hydro in Glasgow, health bosses said.
The new cases bring the total number to 15 and are all linked to events at the venue on January 17, 18 and 19.
An investigation by NHS Greater Glasgow and Clyde (NHSGGC) alongside other public health bodies has indicated that burgers sold at the Hydro could have been the cause of the outbreak.
