The number one reason for shutting down an investigation is when the government already knows the answer, but has no acceptable solution to it. In this case, possible reasons include: (1) prions, with a possible spread into the soil and plants (2) neurotoxins like BMAA etc. from seafood (3) brain eating amoeba. If it's #1, "god help NB" because short of incinerating the whole region with a hydrogen bomb, there is not much else that can be done. If it's #2, neurotoxins from seafood, stopping them will decimate the local seafood industry, ergo taxes and exports, so the government has a lot to lose by taking action. If it's #3, the government would still be on the hook for inadequate water purification.
