Warming seas push pufferfish species together in Japan, raising toxicity risks

Techub, citing the South China Morning Post, reported that rising sea temperatures are forcing different pufferfish species into closer contact and producing hybrids that even trained chefs cannot safely prepare. In Japan, "fugu" is the collective name for several edible pufferfish species and is known not only for its delicate taste but also for the danger involved in preparing it. Many species carry tetrodotoxin, a potent neurotoxin with no known antidote. Exposure can lead to paralysis, respiratory failure, and death. The report also noted that Japan has required a license to prepare pufferfish for public consumption since 1958. Obtaining that license takes at least two years, and roughly two-thirds of candidates fail the process.
