trust me, you will know when it's bad. There are few things in this world that smell as bad as a rotten potato. It may also be slimy. Those 'barnacle things' are fine. The potato is a root, those things are just shoots. Rub them off and you'll be fine.
Malignant hyperthermia (MH) is a rare, inherited skeletal muscle syndrome that presents as a hypermetabolic reaction triggered by exposure to volatile anesthetic gases or the depolarizing muscle relaxant, succinylcholine. 1,2 The incidence of MH is difficult to quantify.
Furthermore, it is clear that the vast majority of prescription and non-prescription drugs will not trigger MH. Despite the knowledge of which agents will and will not trigger MH, the reason why they trigger MH is still a mystery. Not everyone who has MH develops an episode each time a triggering agent is given to him or her.
