For those unaware: the reason boar are singled out is that they forage by digging up the ground, so they're more likely to be directly affected by contaminated soil, even if the contamination would normally be underground at this point. I'm not sure what the situation is with burrowing animals like rabbits but I'd wager the problem with boar is also that they are more likely to actually ingest contaminated soil in addition to simply being covered in it.
