People who visited the Street Spice food festival in Newcastle are being asked to fill out an online questionnaire after hundreds of people reported symptoms of food poisoning.
Environmental Health Officers are continuing to investigate and are talking to businesses and suppliers to try to identify the source of the outbreak, with results expected to be released this week.
12,000 people are thought to have visited the food festival while it was in the city.
Anyone who attended the event, whether they have been ill or not, are being advised to complete a confidential online questionnaire, available at http://tinyurl.com/streetspice.
