The hearts of 893 sows from Iowa killed for food between January 1990 and February 1992 were examined for Sarcocystis bradyzoites by the digestion technique. Bradyzoites were found in 163 (18.2%) hearts. Sections of formalin-fixed tissues from 28 hearts with demonstrable bradyzoites were examined for sarcocysts. Sarcocystis miescheriana sarcocysts were found in six pigs. The prevalence of Sarcocystis was apparently not affected by season.
1990年1月至1992年2月间，对爱荷华州893头被宰杀以供食用的母猪心脏进行了检查，采用消化技术检测其中的缓殖子。在163头（18.2%）母猪的心脏中发现了缓殖子。对28颗发现有明显缓殖子的心脏进行福尔马林固定组织切片检查，以寻找肉孢子虫囊。在6头猪中发现了米氏肉孢子虫囊。肉孢子虫的流行率显然不受季节影响。
