Actually I did consider that, except I figured a) if it happened here it could just as easily happen at any other laundromat, and b) if I choose the washers and dryers furthest from the door, it's less likely to be contaminated. The landlord bit I also agree with, but there are no cameras so it'd be my word against hers.  I don't want to make enemies of someone who, at any given time, could reach into themself, pull out a wad of pressure-cooked bio revenge, and plaster my car with it.
