If you have young children, you've probably heard about the homemade slime craze that's making the rounds.

You've also likely heard about some of the concerns about its ingredients, which are reported to have injured some kids.

Southern Health-Sante Sud Vice-president of Medical Services Dr. Denis Fortier says one of the ingredients is borax.

"When we're mixing it together with these products, you're exposed to some of these irritants," he says, "And especially in the powder form, it can get into your nose, into your mouth, and certainly, when you're playing with it, and it can cause a slight irritation, or sometimes for people who are very sensitive, it can actually cause a bit of a burn."

Fortier urges parents to make the slime themselves.

"Because part of the risk is also in the amount of time that you're exposed to the irritant," he says, "So if the child is not only fabricating the slime, but then spending an hour or two playing with the slime, you've just increased the amount of time that person has been exposed to the homemade slime."

He adds if there's homemade slime in your home, it's a good idea to keep it in a safe place.

"These are home made, so it's probably not passed all the safety tests that other products have passed," he says, "So I would say you want to treat this with a little bit of respect, and if the children are not playing with the product, store it safely, higher than where the children can get at it, so that they're not inadvertently exposing themselves for long periods of time."

Fortier adds he's heard of no injuries related to homemade slime in Southern Health.
