Xenodiagnosis involves feeding suspected muscle to laboratory rats. Cook all garbage fed to hogs. Proper meat handling, ordinary curing and salting of pork products will not kill encysted juveniles. Freezing is effective if carried out properly. The freezing requirements differ with the size of the meat.

Quick freezing and storage for 2 days is effective. Although there have been marked reductions in the percentage of hogs carrying encysted juveniles in the United States, there is considerable variation from one part of the United States to another. It is therefore a wise precaution to avoid uncooked pork products. Relieve symptoms with analgesics and corticosteroids. The males measure 1.4 to 1.6 mm long and are more slender at the anterior than the posterior end.
