Halton police are warning parents to re-check any Halloween candy their kids might have around the house after a Burlington mother discovered a cold tablet in her daughter’s stash Wednesday.

Police said the woman opened a small, sealed box of Smarties intending to have a treat and found a single, Tylenol “DM” cold tablet inside the box.

She checked the other boxes and noted that they were all sealed and only half full. The box containing the cold pill had been completely filled to the top.

Detective Sergeant Walt Bucci said the candy was collected Halloween as the family went trick or treating in the McCoy Avenue-Ironstone Drive neighbourhood around Appleby Line and Upper Middle Road in Burlington.

Bucci said this is the only report of candy being tampered with police have received in Burlington.

Tylenol pills have appeared in Smarties boxes in Durham Region and Pickering this year.

Yesterday, Durham police reported two new cases of tampered Smarties candy in Pickering, bringing the total to seven.

A Grade 5 student at Valley Farm Public School found a DayQuil capsule inside a sealed box of Smarties on Nov. 5 that she got while trick-or-treating. Since then, additional reports have been streaming in, said Durham police Sgt. Paul McCurbin.

All seven confirmed reports stem from boxes of Smarties handed out on Halloween in the Brock Rd. and Finch Ave. area in Pickering.

Nestle, the makers of Smarties, said in a statement it was co-operating with Durham police.

"At Nestle, safety is our highest priority so we take these matters very seriously," the statement said. "To this end, we are actively working with the police who are leading this investigation.”

Bucci said Burlington detectives are following up on the find and police are asking parents to check their kids’ Halloween treats carefully.

Anything suspicious should be reported to police

He also said if a child consumes any unknown capsules, parents should call 911 or the Poison Control Centre at 1-800-268-9017 immediately
