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)
The aim of this study was to determine the effect of different concentrations of table salt (NaCl) and ethanol (v/v) solutions on the viability of Alaria alata mesocercariae. Furthermore, the survival of A. alata mesocercariae during simulated human gastric digestion was evaluated. For this purpose, A. alata mesocercariae migration technique (AMT) was used(More)
Recent findings of Alaria alata mesocercariae in wild boars and other animals in Europe reinforced the concern about the public health risk posed by this parasite especially if the game meat is insufficiently heated during preparation. Cooking and freezing are effective methods for the inactivation of parasites in meat whereas refrigeration is considered as(More)
Proficiency testing (PT) is the use of inter-laboratory comparisons to determine the performance of individual laboratories for specific tests or measurements, and to monitor a laboratory's performance. Participation in proficiency testing provides laboratories with an objective means of assessing and demonstrating the reliability of the data they are(More)
This study investigated the benefits of hot-water spraying (HWS) as a diagnostic test to verify the absence of signs of life (SOL) before scalding in pigs slaughtered with carbon dioxide (CO2) stunning. A total of 37 108 finishing pigs from five German abattoirs (A to E) operating at 55 to 571 pigs per hour were assessed. Suspended pigs were sprayed onto(More)
BACKGROUND The slaughter of pregnant cattle and the fate of the foetuses are relatively new subjects in the field of animal welfare. The Scientific Committee on Veterinary Measures relating to Public Health (SCVPH), however, does not believe this topic to be a critical issue because of the hitherto supposed rare occurrence of this practice. Some previous(More)
Trichinosis (Trichinellosis) is a zoonotic disease acquired by eating raw or not adequately processed pork or wild game infected with the larvae of the roundworm genus Trichinella. According to European regulations, animals susceptible to Trichinella have to be examined for infestation. To evaluate the performance of laboratories in Germany,(More)
