  • Game Meat: Health Assessment of Human-Pathogenic Parasites
    Bundesinstitut für Risikobewertung www.bfr.bund.de DOI 10.17590/20190627-084353 Game meat: health assessment of human-pathogenic parasites BfR Opinion No. 045/2018, 21 December 2018 Meat of game living in the wild, such as deer, roe deer and boar, is rich in nutrients, low in fat and commonly sustainably sourced. It may, however, contain parasites that can make people ill if the meat has not been prepared in a hygienically flawless manner. There are often un- certainties in the hygienic assessment of meat from hunted game – for example in case of parasite infestation, regarding localization of parasite infestation sites within the animal car- cass. These uncertainties are also due to the limited amount of data on these specific patho- gens in game. The German Federal Institute for Risk Assessment (BfR) has therefore con- ducted an evaluation of own and existing data in order to determine the game species and specific organs respectively in which the parasites listed below have been detected and on the frequency of infestation occurrence. The BfR has used this information to assess the risk of contracting a parasitic disease from consumption of game meat and has put together rec- ommendations on how consumers can avoid such illnesses. In its health assessment, the BfR has considered game species only, whose meat and prod- ucts made from their meat are typically consumed, namely boar, deer, roe deer and fallow deer. Acquired data sets on consumption of game meat show that both adults and children in Germany consume game meat only rarely and only in small quantities.

  • AFSSA1 on the Risk to Public Health Associated with the Presence of This Parasite in Wild Boar Meat (Opinion 2007-SA-0008) Was Issued on 14 September 2007
    ANSES Opinion Request No 2015-SA-0052 Related Request no. 2007-SA-008 The Director General Maisons-Alfort, 16 December 2015 OPINION of the French Agency for Food, Environmental and Occupational Health & Safety on the presence of mesocercarial parasites of the trematode Alaria alata in wild boar meat ANSES undertakes independent and pluralistic scientific expert assessments. ANSES's public health mission involves ensuring environmental, occupational and food safety as well as assessing the potential health risks they may entail. It also contributes to the protection of the health and welfare of animals, the protection of plant health and the evaluation of the nutritional characteristics of food. It provides the competent authorities with the necessary information concerning these risks as well as the requisite expertise and technical support for drafting legislative and statutory provisions and implementing risk management strategies (Article L.1313-1 of the French Public Health Code). Its opinions are made public. This opinion is a translation of the original French version. In the event of any discrepancy or ambiguity the French language text dated 16 December 2015 shall prevail. On 26 February 2015 the French Agency for Food, Environmental and Occupational Health & Safety received a formal request from the Directorate General for Food for an opinion on the presence of mesocercarial parasites of the trematode Alaria alata in wild boar meat. 1. BACKGROUND AND PURPOSE OF THE REQUEST Screening for Trichinella in wild boar carcasses sometimes reveals larvae of the trematode Alaria alata. A first opinion by AFSSA1 on the risk to public health associated with the presence of this parasite in wild boar meat (Opinion 2007-SA-0008) was issued on 14 September 2007.

  • Zoonotic Helminths Affecting the Human Eye Domenico Otranto1* and Mark L Eberhard2
    Otranto and Eberhard Parasites & Vectors 2011, 4:41 http://www.parasitesandvectors.com/content/4/1/41 REVIEW Open Access Zoonotic helminths affecting the human eye Domenico Otranto1* and Mark L Eberhard2 Abstract Nowaday, zoonoses are an important cause of human parasitic diseases worldwide and a major threat to the socio-economic development, mainly in developing countries. Importantly, zoonotic helminths that affect human eyes (HIE) may cause blindness with severe socio-economic consequences to human communities. These infections include nematodes, cestodes and trematodes, which may be transmitted by vectors (dirofilariasis, onchocerciasis, thelaziasis), food consumption (sparganosis, trichinellosis) and those acquired indirectly from the environment (ascariasis, echinococcosis, fascioliasis). Adult and/or larval stages of HIE may localize into human ocular tissues externally (i.e., lachrymal glands, eyelids, conjunctival sacs) or into the ocular globe (i.e., intravitreous retina, anterior and or posterior chamber) causing symptoms due to the parasitic localization in the eyes or to the immune reaction they elicit in the host. Unfortunately, data on HIE are scant and mostly limited to case reports from different countries. The biology and epidemiology of the most frequently reported HIE are discussed as well as clinical description of the diseases, diagnostic considerations and video clips on their presentation and surgical treatment.

[ 1 ]. Members of the superfamilies Schistosomatoidea (Schistosomatidae, Aporocotylidae, and Spirorchiidae) and Diplostomoidea (Diplostomidae and Strigeidae) will be characterized. All these fl ukes have indirect life cycles with cercariae having ability to penetrate body surfaces of vertebrate intermediate or defi nitive hosts. In some cases, invasions of accidental (noncompat- ible) vertebrate hosts (including humans) are also reported. Penetration of the host body and/or subsequent migration to the target tissues/organs frequently induce pathological changes in the tissues and, therefore, outbreaks of infections caused by these parasites in animal farming/breeding may lead to economical losses. 10.2 Schistosomatidae Members of the family Schistosomatidae are exceptional organisms among digenean trematodes: they are gonochoristic, with males and females mating in the blood vessels of defi nitive hosts. As for other trematodes, only some members of Didymozoidae are P. Horák (*) • L.

Histological MNP Müritz National Park NTC Nontemplate control examination of cryotome sections of frozen as well as Syn Synonym paraffin-embedded tongues were used to identify parasite cysts. These were located in the connective and adipose tissue and in close proximity to small arterioles, suggesting a hema- togenous spread of the parasite.

  • Alaria Alata Mesocercariae in Domestic Pigs and Wild Boars In
    Comparative Immunology, Microbiology and Infectious Diseases 63 (2019) 142–144 Contents lists available at ScienceDirect Comparative Immunology, Microbiology and Infectious Diseases journal homepage: www.elsevier.com/locate/cimid Alaria alata mesocercariae in domestic pigs and wild boars in South Banat, northern Serbia T ⁎ Pavle Gavrilovića, , Ivan Pavlovićb, Igor Todorovićc a Veterinary Specialized Institute “Pančevo”, Department of Pathology and Parasitology, 26000, Pančevo, Serbia b Scientific Veterinary Institute of Serbia, Department of Parasitology, 11000, Belgrade, Serbia c Veterinary Specialized Institute “Pančevo”, Department of Animal Health, 26000, Pančevo, Serbia ARTICLE INFO ABSTRACT Keywords: Alaria alata (Diplostomidae, Trematoda), a potentially zoonotic pathogen, is the only Alaria species in Europe. In Alaria alata recent years, increasing reports of mesocercariae of A. alata in wild boars have been recorded in European Mesocercariae countries; however there have been no described cases in domestic pigs over the past decades. Out of 272 Domestic pigs diaphragm samples from wild boars (Sus scrofa) and domestic pigs (Sus scrofa), from Serbia, included in the Wild boars present investigations, mesocercariae of A. alata were found in six (3%) samples from wild boars and in two Serbia (2.77%) samples from domestic pigs. Due to the lack of sensitivity of artificial digestion with a magnetic stirrer which was applied in the study, the true prevalence is estimated to be considerably higher in the area of in- vestigation. Confirming the infection in domestic pigs and a wide distribution in wild boars in the area of investigation, the present paper should influence the growing awareness of alariosis as a potential human dis- ease. The meat from free-range domestic pigs and game meat as a potential source of alariosis should always be adequately thermally treated before consumption.
