The Health Protection Agency have released a statement after nearly 200 cases of sickness were reported following a food festival held in Newcastle.
The Street Spice festival visited Newcastle last week and is thought to have been attended by 12,000 people over the course of its visit.
“Initial investigations have not yet identified a definite source of infection, however, we are working closely with the organisers of the event to determine the source of infection.
"Anyone who is concerned about symptoms suggesting salmonella infection should contact their GP or out-of-hours service in the first instance.
"Those affected should not return to their place of work until their symptoms have ceased for 48 hours.”
