In pigs, malignant hyperthermia (MH) or Porcine Stress Syndrome (PSS or Hal 1843) leads to rapid post-mortem changes in muscle, resulting in a bad quality of meat. MH can be triggered by minor stress, such as loading, transport, sexual intercourse, high ambient temperature, or exposure to the anaesthetic halothane. It was established that PSS is due to a change in the gene for the calcium release channel in skeletal muscle (altered calcium flow).

PSS was a major economic problem in many countries in the 1970s. In part, this was due to strong selection for increased leanness, which is associated with susceptibility to PSS.
