The BBC reports that seven people – one from Glasgow, two from Lanarkshire, three from Lothian and one from Cumbria – are recovering from E. coli O157:H7 at home after being diagnosed.
Health officials say the cases may be linked to burgers sold at The Hydro.
Anyone who attended the venue between 17 and 25 January, and who feels unwell, is asked to contact their GP.
Symptoms to look out for include stomach cramps, diarrhea (often bloody), nausea and fever.
The seven people who contracted the infection all attended Top Gear Live on 18 and 19 January.
