“…The mesocercaria can survive several host transitions unharmed. After breaking through the intestine wall of the new host, it behaves as in the preceding host (Bosma 1934, Hiepe 1985, Lutz 1933a, b, Lutz 1921, Odening 1963, Pearson 1958, Pearson 1956, Schnieder 2006. Adult flukes, residing in the intestines of the definitive hosts, pass unembryonated eggs through the feces of the host.…”

“…Overall pathogenicity is correlated to high infestation densities, in particular, after repetitive intake of mesocercariae. The transition of the mesocercariae from one paratenic host to another fails to decrease infectivity of the parasite (Bosma 1934, Dönges 1969, Hiepe 1985, Lutz 1933a, b, Lutz 1921, Odening 1963, Pearson 1958, Pearson 1956, Schnieder 2006. Since 1973, several reports about human larval alariosis have been published as summarized in Table 5.…”

Biology of Alaria spp. and human exposition risk to Alaria mesocercariae—a review

Recent incidental background findings of Alaria alata mesocercariae ["Distomum muscularis suis," Duncker, 1896] in meat of wild boars during official Trichinella inspection initiated a re-assessment of the potential human health risk as posed by this parasite. The present review of the literature on Alaria biology shows that the human exposition risk should no longer be accepted to be negligible, as it demonstrates a general lack of knowledge in relevant areas of Alaria biology confounding any risk analysis. Sound risk assessment needs future studies which should concentrate on the most pressing questions of (1) the optimization and/or development of methods for reliable Alaria mesocercariae detection, (2) the distribution of the mesocercariae within their paratenic hosts, i.e., identification of potential predilection sites, particularly in wild boars, and (3) their prevalence in sylvatic populations of animals with respect to their introduction into the human food chain. Further, the degree and possibly also the species specificity of Alaria mesocercariae tenacity within the paratenic hosts and respective meat as pertaining to food technological treatments need to be elucidated. While these questions remain unanswered, it is an incontrovertible fact that Alaria mesocercariae have a potentially high human pathogenicity by both occupational and alimentary exposition.

“…Die Pathogenität ist vor allem durch die in diesen ,,Sammelwirten'' auftretenden hohen Befallsdichten nach wiederholter Aufnahme der Mesozerkarien bedingt. Weiterhin ist zu beachten, dass bei einer Übertragung der Mesozerkarien von einem auf den anderen paratenischen Wirt, also auch auf den Menschen, kein Verlust der Infektiosität zu beobachten ist (Eckert 2008;Odening 1963;Pearson 1958;Pearson 1956).…”
