Parasite becomes a danger for the Florida key deer : A Long-Gone Parasite Returns to Florida, Leaving a Trail of Dead Deer
Horrible. The article gives no indication what the cause is. It also doesn't mention that eradication only applied in continental North America. Right off Florida's shores lies a certain screwworm-infested worker's paradise, and the impulse of pretty much everyone in South Florida is to blame Cuba for anything that goes wrong. So of course some people are saying that trade with Cuba may have caused this. However it's odd that it first appeared in the Florida Keys, and not like Key Largo, but way down in the Lower Keys among wild deer. This suggests to me that it's not legal trade, which is responsible, but rather smuggling. Of course the legal trade may have made smuggled goods easier to pass off as legit.
