After consuming poor quality pork containing the cysts of the worm, larvae are liberated in the digestive system by the digestive juices. The larvae invade the small intestine mucous membrane and mature rapidly into adult worms. After seven days, female worms release newborn larvae that migrate via the bloodstream to the skeletal muscles. In the muscles the larva gets encysted.
