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(More)
The trematode Alaria alata, an intestinal parasite of different carnivore species is widely distributed throughout Europe. The mesocercarial stages of Alaria spp. may infect almost all vertebrate species, including humans, and, in particular, omnivorous scavengers such as wild boars serve as paratenic hosts for the parasite. The introduction of the A. alata(More)
Several methods for the detection of tissues of the central nervous system (CNS) in meat products have been developed and partly validated for use in official food control as pertaining to human BSE-exposure risk. So far, however, methods for the detection of abnormal prion protein (PrPSc) were not evaluated for their potential applicability to the matrix(More)
Distomum musculorum suis (DMS), the mesocercarial stage of the trematode Alaria alata, can cause severe damages within their hosts, and since several reports about cases of human larval alariosis have been published, it became apparent that infected game animals and in particular wild boars are a potential source of infection for both humans and animals. A(More)
Identification of bovine and ovine tissue from the central nervous system (CNS: brain and spinal cord) in meat products is possible by using certain CNS fatty acids as biomarkers in GC-MS analysis. Furthermore, the relationship between the isomers of the tetracosenic acid (C24:1) is important for differentiation of the species and age of the CNS in view of(More)
Over the last decade, incidental findings of Alaria alata in stocks of German wild boar during the official Trichinella inspection have been increased. As early as 2006, the German Federal Institute for Risk Assessment pointed out the possible health risk to the consumer posed by this trematode. However, at that time, reliable data concerning the prevalence(More)
From June 2011 to February 2012, a total of 451 wild boar carcasses from eastern regions of Austria were tested for the presence of Alaria alata mesocercariae by means of a migration technique. Mesocercariae were recovered from carcasses from the province of Lower Austria (25/337 carcasses) and the Burgenland (5/64), but not from Vienna (0/50). In positive(More)
Emerging and re-emerging zoonotic diseases affect both public and animal health and require the development and contemporary implementation of suitable detection methods. A growing number of findings of the mesocercarial stage of the digenean trematode Alaria alata in game inhabiting wetlands have necessitated the development of a specific detection method.(More)
Alaria alata is a trematode of carnivores from Europe. The mesocercarial stage was recently identified in wild boar meat from Europe. Previous histopathologic studies showed the presence of unidentified parasitic cysts within the tongues of raccoons from northern Germany. For identification of the parasite species, tissue samples of 105 raccoons originating(More)
To date classification and differentiation of Alaria spp. are based largely on external characteristics and comparative morphology of adult flukes. The accurate differentiation between various Alaria spp. mesocercariae is indeed difficult because there are only few data on morphological and morphometrical features of the parasite’s developmental stages. We(More)
