Two epidemiologically unrelated outbreaks of trichinellosis were registered in Rostov Province in the November and December of 1984 with 16 patients in the Salsk District and 20 patients in Rostov-on-Don. The course of the disease was characterized by 6-20% of severe and 31-45% moderate forms, respectively. The source of the infection was pork that had not been controlled for Trichinella spiralis. Late diagnosis and inadequate treatment in one case led to a fatal outcome. Economic losses accounted for 490,000 rubles (as of 1985). In spite of energetic prophylaxis measures, the situation in the Rostov Province continues to be serious. In 1989-1992, eighteen cases of trichinellosis were registered in the Salsk District again.
