New details emerge following mass poisoning at Markham, Ont. restaurant

As many as 12 people sought medical attention after eating at a Markham restaurant this past weekend and four individuals remain in intensive care.

York Region’s Medical Officer of Health, Dr. Barry Pakes, shared the new details with CP24 Tuesday morning regarding the mass poisoning at Delight Restaurant & BBQ, which is located at Castlemore Avenue and Markham Road.

“We do suspect that it was something called aconite, which is a toxin that can be found in various herbs or roots, or in particular one flower,” Pakes said, adding that testing is currently underway to confirm their theory.

The region’s top doctor said the toxin can be “accidentally mixed in with other things or intentionally,” but that there is no reason at this time to believe that the suspected poisoning was intentional.

Aconite has the potential to be deadly, and can cause diarrhea, convulsions, or arrhythmias.

Pakes could not speak to the condition of the patients currently in intensive care aside from saying they are “still quite ill” and that “anybody who goes to the ICU is in pretty life-threatening condition.”

He said that the “good news” is that those patients do appear to be “getting better” following their admission to hospital.

Delight Restaurant & BBQ is now closed and anyone who ate any food from the restaurant — including dine-in, takeout, or delivery — on Aug. 27 or Aug. 28, and is experiencing symptoms, is being encouraged to seek medical attention.

Officials say that the restaurant is cooperating with the investigation. Records show that the eatery passed a health inspection in May.

Pakes added that the poisoning does look “similar” to other recent events, including an incident in Burnaby, B.C. earlier this year which saw two people attend hospital with heart irregularities following the purchase of sand ginger powder from a local mall.

In a statement to CTV News Toronto, Public Safety Minister Marco Mendicino’s office said they were aware of the “concerning” situation in Markham.

“We will continue to monitor for further details provided by the police of jurisdiction – the York Regional Police – as well as regional health authorities as the situation unfolds,” the statement read.
