Hi L.,
Unless you hear about a recall for a particular brand, or hear something on the news about it (I haven't heard anything, and I watch the news quite a bit). I once heard about some type of vinyl mattresses, the baby crib, toddler bed kind that might have been recalled a year or two ago, check with the place you bought it, or the brand/company itself. If this is not the case, I wouldn't worry about it. Just put a sheet over over the mattress cover, (I am assuming that is what you do).
