Condemnation of beef because of Sarcocystis hirsuta infection.
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.
