肉毒毒素是由肉毒梭菌产生的一种神经毒素。肉毒梭菌，又称肉毒杆菌、肉毒梭状芽孢杆菌，是自 然界中常见的细菌，广泛分布于自然界，如土壤、海洋沉积物、动物肠道中，本身并不致病。但当它在 缺氧环境中大量繁殖时，分泌出的毒性极强的肉毒毒素，该毒素成为让人中毒的"元凶"。 肉毒毒素依据抗原性不同，目前已发现有多种血清型：A、B、E、F型对人类有致病性；C、D型主 要引起动物中毒。其中A型毒性较强，但它也有弱点，对高温和碱性环境抵抗力差，80℃以上加热30分 钟，就能让它失去毒性。 人民网北京10月10日电 （记者乔业琼）打开网购快递，撕开真空袋，浓郁的麻辣香气瞬间飘满房 间——对不少人来说，即食鸡架是宅家追剧、加班解馋的"心头好"。但很少有人知道，这口让人欲罢不 能的美味背后，可能藏着看不见的健康隐患：肉毒毒素。中疾控微信公众号发布消息，看似方便安全的 真空包装鸡架，若生产、运输环节出问题，就可能成为毒素的"温床"。 而且，肉毒梭菌喜欢在18℃-30℃的环境中生长、产毒，一旦环境pH值低于4.5或高于9.0，温度低于 15℃或高于55℃，它就难以繁殖产毒了。因此，加热和冷藏都可以杀死肉毒梭菌。 毒素来源：自然界的 "潜伏 ...
