I highly recommend you read everything on BluePilots regarding the issue as well as ALL of the other resources previously mentioned in this thread.
Flyby can help you get on BluePilots if you don't yet have an account.

Jetblue:"Totally harmless! Nothing to see here!"
A simple web search:" Tri-o-cresyl phosphate poisoning is characterized by numbness of the legs and hands accompanied by weakness or paralysis of these regions, though all symptoms usually only occur after a latency period of 2–3 days. If the dose is substantial, gastrointestinal distress may occur immediately, and the latency period may be shortened. 10–40 days after the onset of numbness, there is a potential for abrupt flaccid paralysis of the toes, feet, and lower parts of the leg, which may be followed by paralysis of the fingers and hands after 4–5 additional days. Fatalities are rare, but there is potential for permanent paralysis, due to death of nerve cells and damage to myelin sheaths.[9]"

Hopefully the issues get resolved in the US before the lawsuits start piling up here, and hopefully future airplanes are bleedless like the 787.
“And Mr Westgate's family, who are seeking £500,000 in compensation, are just one of some 94 separate claims from airline crew demanding damages payment”

Now that I think of it, sometimes on the CRJ when descending into a humid climate (below 18k) I have experienced a foul smell. Is this possibly the toxic wet sock smell? Or some type of water separation issue?

If it were dirty packs/dirty pack filters it’d be a constant smell, because air is constantly going thru them. But it’s intermittent, most common on descent but sometimes on departure as well. And not sure what water separation you are talking about.

There was a video describing the reasons and times this was likely to happen (APU start, initial climb out, descent, almost never cruise), but now its locked behind the APA login page.
The most typical is a small puff of fumes on climb out, which passes and may or may not be noticable, then a major dose on descent as all the oil that has accumulated in the lines during the flight gets released by the wider open valves.

If the issue is the high pressure valve opening at reduced thrust, it shouldn’t be happening on climbout or during APU start. Only descent.
