On Sept. 1, the health agency said there were 19 lab-confirmed cases of Salmonella linked to the booth at Folk Fest, which took place at Gallagher Park between Aug. 10 and 13.
There have not been any cases of Salmonella linked to the Haweli Restaurant itself.
AHS said it worked closely with the music festival and food vendors before the event to ensure all food operators were aware of the requirements under the Public Health Act.
Salmonella typically presents itself within six to 72 hours after ingesting the bacteria in food. Symptoms include diarrhea that may be bloody, abdominal cramps and fever, vomiting and nausea. Salmonella illness can last for several weeks.
Eating contaminated foods is the most common cause of Salmonella. Contaminated foods could include raw or under cooked eggs or egg products, meat, poultry, raw fruit and vegetables.
People can also become exposed to Salmonella bacteria by not thoroughly cleaning surfaces that have been used to prepare raw meat and other foods in the kitchen.
Anyone with concerns can call Health Link Alberta 24 hours a day at 811.
