The Step2 Company issued a recall of the “Step2 Sand & Water Transportation Station” after it was discovered that its train cars’ plastic wheels easily detach and are choking hazards. The company is advising owners of the toy subject to this recall to discontinue the use of this product immediately and contact Step2 for a replacement.
This toy recall effects 60,000 toys in the United States and Canada distributed between December 2008 and June 2010. Apparently, it is the trains with blue wheels and not grey wheels that are subject to this recall although I think the wise decision, that will make most parents comfortable, is to probably just get rid of the toy.
It sounds like Step2 and the federal government were proactive in indentifying the problem but that is just an assumption on my part based on the fact that there do not appear to have been any injuries and also on the fact that there seem to be a lot of similar toys available that are choking hazards where no action has been taken.
You can find more information on the recall from the U.S. Consumer Product Safety Commission website.
