That kind of stuff doesn't usually make it to the news, I know on ReefCentral and most saltwater forums there's been a stickied post about the dangers palytoxins and other corals can have because there seems to be a high profile illness in the hobby from it at least every decade to learn from. Certain corals cause my hands to break out with itchy blisters, but after years of reefkeeping I've learned which ones and sold them off rather than deal with it, wearing gloves makes it really hard to work in the tank.
