Probably the three highest risks are flea markets, the Internet, and discount stores. I won't mention a dollar store by name, but I'll say discount stores. Part of the problem is that 10 years ago, that's the only place you would have seen these. Now we see these in major stores and in major chains in some cases. It's less frequent in major chains, obviously—there's less risk—but we have seen them.
These, for example, have been found in eight hospitals in Quebec and one in Ontario so far.
