The food vendor that had been selling the much-promoted cronut burger at the Canadian National Exhibition remains closed voluntarily as Toronto Public Health continues to investigate a growing number of reports of foodborne illness.
During a Wednesday afternoon news conference, Dr. Lisa Berger, an associate medical officer of health, told reporters that Toronto Public Health was first notified on Tuesday evening that paramedics were responding to "a number of people who became ill on site with foodborne illness."

Berger said the health unit has received reports of "34 cases of persons who have reported symptoms of foodborne illness in relation to eating at the CNE."
Some of the people who became ill at the CNE told officials they had eaten at Epic Burger, which makes the trendy hamburger with a croissant-doughnut mix for a bun.
The food outlet has been closed as a precaution in the wake of the reports of illness.
"Toronto Public Health did not close the premise," Berger said. "The premise was closed by the CNE yesterday evening."
Epic Burger was subject to a three-hour inspection on Wednesday morning, though health officials said it has still not been determined what vendor or food may have made people sick.
"That is only the very beginning of our investigation and we have no confirmation that's the premise where the persons got sick," Berger said.
Illness reported by some cronut burger consumers
CBC News was contacted Wednesday by two people who claim they became ill after eating a cronut burger at the Ex.
One said his wife became sick after eating the cronut burger, as well as seafood chowder fries, ice cream waffles and a smoothie. He, however, did not get ill after eating a cronut burger.
Another man told CBC he felt ill after eating a cronut burger and a slate of other high-fat snacks that included a Canuck burger, sweet potato fries, poutine and a Philly cheesesteak.
Later Wednesday, CBC News spoke to a man who went to the CNE with a group of co-workers on Tuesday night.
They all had fast food, but Kyle Burton said he was the only person to try the cronut burger.
A few hours later, shortly after he got off a ride, Burton started to feel sick.
"I vomited and then I thought, OK, I'm fine now, it was just nausea," Burton said. "But I just kept vomiting … it was awful."
Burton eventually managed to flag a cab to make his way home. He said he continued to feel sick until the early hours of Wednesday morning.
The CNE posted a statement on its website saying it is "very concerned about this situation and the people who have been affected by it."
Anyone who became ill after visiting the CNE on Tuesday is asked to call 311. The CNE can be contacted directly at 416-598-7285.
The Ex opened Friday and runs through Sept. 2. It typically draws more than one million visitors each year.
In recent years, the Ex has offered a number of unusual food items, including deep-fried butter.
