Before you head out the door to take advantage of some Black Friday sales, you may want to check out the annual "Trouble in Toyland" report.

It was comprised by the New York Public Interest Research Group, or NYPIRG, for an in-depth look at toy safety.

This year, the group examined 40 toys for issues, including potential choking hazards and unsafe chemicals, and found 15 you may want to avoid.

The list includes six popular slime toys - Kangaroos Original Super Cool Slime, Kidsco Glow in The Dark Slime, Toysmith Jupiter Juice Slime, iBaseToy Fluffy Slime, Haniex Soft Magic Crystal Slime and Meland Fluffy Slime - that were found to contain boron. The report says that boron, if ingested, can cause nausea, vomiting and long-term reproductive health issues, and can be even be fatal.

The report also highlighted toys that could be potential choking hazards. The report looked at five search pages on Amazon for latex balloons marketed to children under the age of 2 and said 87 percent of the products they found did not have choking hazard labels on them, which is an apparent violation of the law. The report also cited two toys with small parts that it says were not properly labeled as choking hazards for the age groups they were being marketed for.

According to the report, parents should also be wary of privacy concerns with two smart toys - Dash, a robot toy sold by Wonder Workshop, and the Amazon Fire HD Kids Edition tablet - saying that the toys have the chance to expose the private data of children.

"You should really think about if its Wi-Fi-enabled, what kind of information its collecting, what kind of safeties have been put in place so the toy cannot be hacked into.  And if the information is not on the label, not on the box, you should really call the toy manufacturer," said Megan Ahearn, program director with NYPIRG.
