Two children in the Niagara Region had a big scare on Halloween: they both found razor blades inside their candy.

In one incident reported on Sunday in Thorold, Niagara police say the child bit into something hard inside his Kit Kat bar. He immediately stopped chewing and took the candy out of his mouth.

Luckily, the blade never made contact with his mouth and he wasn’t hurt. He told his parents, who called police on Sunday.

Police say the item looked like a blade from a disposable shaving razor.

The packaging of the candy bar may have been tampered with, police say.

In another case, which was reported on Monday, police say a razor blade was found within an O’Henry bar. The child had gone trick or treating in the St. Catharines area.

The child bit down on the chocolate bar, and after removing it from their mouth found the blade inside the candy. No injuries were reported.

Police are reminding parents and guardians to check Halloween candy, looking for any kind of tampering.

Throw away candy that may be a choking hazard for small children, or may cause an allergic reaction, or that is unwrapped.
