A dinosaur balloon-blowing kit and a floating eyeball are among three toys recalled by Health Canada after testing found unacceptable levels of dangerous substances.

More than 310,000 units of the Slimosaurus BlowUp Goop With a Dinosaur Fossil have been recalled after testing by Health Canada found they contained organic solvents that have been banned in Canada since 1973.

The kits, sold at Dollarama between April 2007 and November 2009, come in eight different styles and colours.

The concern is that in blowing up the balloons, children could inhale solvent vapours. Prolonged exposure to the compounds could affect the central nervous system, however neither Health Canada nor Dollarama have received any reports of illness or injury.

Health Canada has recalled this ball because it contains low viscosity petroleum distillates.

A second recall involves the Flashing Eyeball Glideball, which was sold exclusively at Pier 1 stores since September 2009.

The toy is a ball that has a fake floating eyeball inside and various coloured lights that turn on when the ball is knocked against a hard surface. More than 770 units were sold across Canada.

However, Health Canada testing found the recalled toy contains low-viscosity petroleum distillates, which is strictly prohibited in Canada if the substance can be released from the toy on breakage.

Low-viscosity petroleum distillates are highly toxic if ingested or if breathed into the lungs, and could cause central nervous system depression. So far there have been no reports of any illness or injury.

The third toy recall involves the Star Trek Enterprise Bridge play set, imported by RP Toys and sold at stores across Canada.

This Star Trek toy set was recalled because some coatings contain high levels of barium.

Health Canada testing found the coatings of some parts of the toy set, specifically, the bridge of the USS Enterprise, contains barium in excess of the allowable limit.

Barium exposure can cause nausea, vomiting, diarrhea and cramps, however no reports of illness have been reported. Just under 1,000 units have been sold.

Health Canada has advised that the balloon set and USS Enterprise can the thrown out in regular household garbage but that they should contact their municipality for instructions on how to dispose of the eyeball.
