title: Condemnation of beef because of Sarcocystis hirsuta infection.
abstract: Carcasses from 18 Holstein cows from Nevada, California, and Oregon were condemned because of grossly visible sarcocysts of Sarcocystis hirsuta. Sarcocysts were white to dull white, 2 to 7 mm long, and approximately 1 mm wide. Sarcocysts were most numerous in muscles of diaphragm, flank, and limbs and were able to infect laboratory-raised cats.
