Some comments on the outbreak of Trichinellosis in Mosina Province of Poznan
K voprosu ehpidemii trikhinelljoza v Mosine
The author describes the biggest epidemic noted up to now in Poland which was probably also the biggest one ever registered in the world. This epidemic occured in a village called Mosina, near Poznań, in June 1960. Although only 286 persons have been hospitalized, out of which 2 patients died, the incidence of the epidemic has been stated mainly on base of eosinophily found and other symptoms noted in 1122 persons. In the whole, the said epidemic ought to be considered as a mild one, in view of the clinical symptoms observed and taking into consideration the incubation period stated with a great probability in 546 cases. True enough that the detailed epidemiologic investigations did not give sufficient evidence as to the source of infestation, yet, the author was able to draw his own conclusions based on numerous facts and statements collected in this matter. In a locality where Trichinellosis in pigs was not registered since many years four pigs reared in a fox breading farm became infested. The animals in that farm were fed with meat refuse. Out of this number three pigs were sent to be slaughtered the 24 V 1960. Trichinoscopic examination revealed Trichinellosis in one pig and its meat has been destroyed; the remaining two pigs of the same proprietor were declared to be free from trichinellae and out of their meat ham and sausages were made by two pork-butchers living in the same place. These two pigs were probably the source of the epidemic. The fourth pig which was killed the 6 VII 1960 had also triehinellae. Thus, the epidemic in Mosina is an exeeptional one amoung the quoted in literature up to now. They were really two epidemies originating from two different pigs, which occured in the same time and caused such a great number of morbid incidents.
