Warmer oceans are now linked to dangerous neurotoxins in shellfish

A mysterious, potentially deadly neurotoxin that poisons humans by way of shellfish has now been linked to warming ocean waters. The new findings could help fisheries predict spikes of this substance in their catches, allowing them to protect human consumers and mitigate their own financial losses. But one question remains unanswered: as climate change edges ocean temperatures higher and higher, will blooms of the dangerous neurotoxin follow suit?
