Cronut burger is the source of food-borne CNE illness: Toronto Public Health
With 150 people now reporting they got sick after eating one, testing finds samples contained a bacterial toxin not destroyed by cooking.

The cronut burger has been positively identified as the cause of an outbreak of food-borne illness at the CNE.
Samples of the dish were contaminated by Staphylococcus aureus toxin, said Dr. David McKeown, Toronto’s medical officer of health, who added that it can cause symptoms such as diarrhea, vomiting and cramping within two to four hours of ingestion.
The bacteria tend to multiply in food in the presence of inadequate temperature control or food hygiene, however, the resulting toxin — which is what makes you sick — is resistant to heat.
“It has happened in other outbreaks where the bacteria grow, they produce the toxin and then you cook the food, which kills the bacteria, but it doesn’t kill the toxin,” said McKeown, who added that Toronto Public Health doesn’t yet know if that’s the case in this investigation.
Public Health has interviewed 100 people who fell ill after eating at the CNE between Aug. 16 and Aug. 20, and the only common food they consumed was the cronut burger, a cheeseburger-croissant-doughnut fusion sold by Epic Burgers and Waffles.
By 10 a.m. Friday, Public Health had received reports from 150 people who came down with symptoms of food-borne illness after eating at the CNE during that time period.
“If we had closed them, their Dine Safe status would be red,” said McKeown.
The CNE voluntarily shut down Epic Burgers and Waffles Tuesday evening as the number of people reporting gastrointestinal troubles began to climb.
“If we had closed them, their Dine Safe status would be red,” said McKeown, referencing the red “closed” notice used in the city’s food safety program, which inspects establishments serving and preparing food and posts either a green pass, a yellow conditional pass or a red closed notice for the public.
“Based on information from the ill individuals, the only common food exposure they had was the cronut burger served by Epic Burger. There were no indications from that investigation of any other CNE food associated with this outbreak,” McKeown said.
On Thursday night, Epic Burgers and Waffles released a statement on its Facebook page pointing to its squeaky clean track record.
“In the time that we’ve been operating at the CNE we have had a clean bill of health and all our staff have been fully trained in food safety. We buy our products from only the top suppliers and we’ve never had any issues in the past, nor do we wish to have any in the future.”
CNE general manager David Bedar expressed confidence that the outbreak is over. “We are committed to take whatever actions may be necessary in order to prevent any similar outbreak from occurring in the future.”
Toronto Public Health still doesn't know which part of the cronut burger dish caused the outbreak; however, the bacterial toxin tends to contaminate foods such as meats, poultry and eggs, or foods that require considerable handling and are kept at room temperatures after preparation.
“Until the investigation determines the precise cause or source of the outbreak, we will not allow Epic Burgers to reopen,” McKeown said.
