“…The Suidae and the Cervidae families host numerous parasites (eight and five respectively), with Cryptosporidium, Giardia, Toxoplasma gondii and Trichinella species harboured by both (Table 4). Trichinellosis poses an important disease risk because human cases related to the consumption of improperly cooked, inadequately frozen or cured wild pork and venison have been reported globally (Serrano et al 1989;Rodríguez et al 2004;García et al 2005;De Bruyne et al 2006;Meng et al 2009), including in Southeast Asia (Ramasoota 1991;Jongwutiwes et al 1998). In Southeast Asia, certain cultural food practices using this wild meat increase the infection risk, such as eating it raw in Thailand (Kaewpitoon et al 2008) or undercooked in Papua New Guinea (Owen et al 2005).…”

A Review of Zoonotic Infection Risks Associated with the Wild Meat Trade in Malaysia

2017

The overhunting of wildlife for food and commercial gain presents a major threat to biodiversity in tropical forests and poses health risks to humans from contact with wild animals. Using a recent survey of wildlife offered at wild meat markets in Malaysia as a basis, we review the literature to determine the potential zoonotic infection risks from hunting, butchering and consuming the species offered. We also determine which taxa potentially host the highest number of pathogens and discuss the significant disease risks from traded wildlife, considering how cultural practices influence zoonotic transmission. We identify 51 zoonotic pathogens (16 viruses, 19 bacteria and 16 parasites) potentially hosted by wildlife and describe the human health risks. The Suidae and the Cervidae families potentially host the highest number of pathogens. We conclude that there are substantial gaps in our knowledge of zoonotic pathogens and recommend performing microbial food safety risk assessments to assess the hazards of wild meat consumption. Overall, there may be considerable zoonotic risks to people involved in the hunting, butchering or consumption of wild meat in Southeast Asia, and these should be considered in public health strategies.Electronic supplementary materialThe online version of this article (doi:10.1007/s10393-017-1229-x) contains supplementary material, which is available to authorized users.

“…Several studies have detected Trichinella spp. in wild animals such as rodents species, wild boar Sus scrofa, big hairy armadillo Chaetophractus villosus, cougar Puma concolor (Tesón et al, 1997;García et al, 2005;Krivokapich et al, 2006;Ribicich et al, 2010a) white-eared opossum Didelphis albiventris and little water opossum Lutreolina crassicaudata (Castaño Zubieta et al, 2014). However, so far very little is known about the wild Cycle of Trichinella genus in Argentina.…”

Trichinellosis is a food-borne parasitic disease produced by different nematodes of the genus Trichinella. In Argentina, it is an endemic zoonosis and an important public health problem. The infection has been detected in domestic and wild animals. Trichinella spp. muscle larvae have anaerobic metabolism, which allows their survival in decaying tissues. The aim of this study was to evaluate the presence of Trichinella spp. in carnivorous and/or scavenger wild vertebrates-birds, mammals and reptiles-in northeastern Argentine Patagonia. Skeletal muscle samples from 141 animals, which were found killed on northeastern Argentine Patagonia roads, were analyzed by the artificial digestion method. None of the 141 samples were positive for larvae of Trichinella. These results suggest that Trichinella does not use these species to complete its cycle in this region of the continent and the absence of a significant alteration in the study area makes it difficult to transmit parasitic diseases. However, due to the limited number of samples assessed for some species, this could not be confirmed. The relevance of this study resides in the fact that it is the first systematic study in South America that considers birds, reptiles and mammals as potential hosts for Trichinella.

“…There is no report of Trichinella in wild hosts other than in P. concolor in Chile (Álvarez, et al, 1970;González-Acuña, et al, 2010), and rats reported to host Trichinella larvae have been found only in association with human settlements (e. g. Poupin, 1897). Thus, in Chile, the cougar and the wild boar are the only species that represent any evidence of a possibly existing sylvatic cycle of Trichinella (García, et al, 2005;Hidalgo, et al, 2013). In contrast, in Argentina, Trichinella has been documented in wild boar (Cohen, et al, 2010), and it has also been found in the armadillo (Chaetophractus villosus), the central pericote (Graomys centralis), and in a species of fox (Lycalopex gymnocerus gracilis) (Minoprio, et al, 1967;Krivokapich, et al, 2006).…”

“…in a cougar, but without genotypic identifi cation. There is also one report of human trichinellosis associated with the consumption of wild boar (Sus scrofa) hunted in the sylvatic environment (García, et al, 2005). In Chile, trichinellosis is considered an endemic disease associated with domestic slaughtering without veterinary supervision (MINSAL, 2011).…”

Research Note. Trichinella spiralis parasitizing Puma concolor: first record in wildlife in Chile

et al. 2015

View full text Add to dashboard Cite

SummaryThe genus Trichinella is widespread in all continents but Antarctica. The only way to identify the species/genotypes is through molecular analyses. In Chile, only one study has reported Trichinella larvae in a cougar, but the species of Trichinella was not identifi ed. In this work, the fi nding of Trichinella larvae in a cougar, together with their genotypic identifi cation, is the fi rst documentation of such in Chile. The cougar was found run over by a vehicle in the Biobío Region. Larvae were isolated following artifi cial digestion of the diaphragm and analyzed by means of multiplex polymerase chain reaction (PCR). A PCR product of 173 base pairs allowed for the classifi cation of the larvae as T. spiralis. It is the fi rst record of the species in Chilean wildlife. This fi nding in Chile is interesting in terms of human health, suggesting a possible role of the cougar as a reservoir for this parasite
