I don't think so, Mycobacterium bacteria can be present in any tank, and not all fish who are carriers display symptoms. If you really want the nitty gritty on it, read here:

It's a good idea to be careful with your hands and avoid injury. Apart from that, there is essentially nothing you can do since there are no tests for this bacteria available to the hobbyist. The way I see it, I bet you are way more likely to get into a fatal car accident - that doesn't stop you from driving, though! I feel a little uneasy when I fly - then I think about how the trip to the airport is statistically, the most dangerous part.
Risk is a part of life, living in fear of everything that might hurt you is not at all productive.
