“…Only one study provided prevalence estimations: 3.23% of 62 wild boars and 2.8% of 820 rodents. This contrasts with a large number of reports on humans, where pigs and wild boars were the main sources of infection, although turtles and bears could also be sources of infection (Barennes et al., 2008; Chotmongkol et al., 2005; Conlan et al., 2014; Doege et al., 1969; Intapan et al., 2011; Jongwutiwes et al., 1998; Khumjui et al., 2008; Kurup et al., 2006; Kusolsuk et al., 2010; Lo et al., 2009; Vu Thi et al., 2014). While only T. spiralis were identified in animals, three species were identified in humans: T. spiralis , T. pseudospiralis and T. papuae .…”

The genus Trichinella has a worldwide distribution, infecting people, domestic animals, and wildlife. It includes 13 genotypes, which are geographically delimited; Trichinella is transmitted to people through the ingestion of undercooked meat. Historically, it has been associated with pigs, but most Trichinella species affect wildlife, and cases of trichinellosis due to the consumption of game meat have been emerging. Therefore, it is important to monitor the sources of transmission to domestic animals and humans.The objective of this work was to analyse reports of Trichinella spp. in wild/feral animals around the world to identify the needs of future research in the epidemiology of the sylvatic cycle. A search of studies published until 2021 was conducted using Web of Science and SciELO. In the Palearctic, the most commonly studied hosts were wild boars and red foxes, and hosts with the highest prevalence rates were polar bears and martens. In the Nearctic, red foxes and black bears were the most frequently studied hosts, and the highest prevalence was found for wolverines and brown bears. In the Neotropics, positive reports were only identified in two countries, with wild boars being the most commonly studied species, and armadillos featuring the highest prevalence. In the Afrotropics, Trichinella limits its presence to Sub-Saharan Africa, where lions are the most studied hosts, and spotted hyenas have the highest prevalence. In the Indo-Malaya and Australasia ecozones, information on wildlife is scarce; the Norwegian rat is the most frequently studied host, and the Tasmanian devil has the highest prevalence of infection. In the last decade, research on world wildlife has increased which is associated with more frequent trichinellosis outbreaks caused by the consumption of wild meat. The results suggest the need to increase research in developing countries, particularly where more diverse sources of meat are available for human consumption.

“…Various researchers have shown that the cooking of garbage before feeding the pigs is constituted as an important step in the control of human trichinellosis elsewhere [13][14][15][16][17]. Therefore, uncooked swill feeding might serve as a source of infection in pigs and kitchen leftover might contain Trichinella infected meat scraps.…”

Abstract.A cross-sectional study was conducted to determine the prevalence and associated risk factors of trichinellosis in slaughtered pigs from three slaughterhouses located in Pyinmana, Lewe and Tatkon Townships, Nay Pyi Taw, Myanmar. A total of 270 muscle samples (tongue, masseter and diaphragmatic muscles from each pig) from 90 slaughtered pigs were randomly collected and examined for the presence of Trichinella larvae by using artificial digestion method. Three pigs (3.3%) showed Trichinella positive and larval intensity per gram (lpg) was 0.2. For the determination of associated risk factors of trichinellosis, questionnaire interviews to officials of slaughterhouses and owners of slaughtered pigs were conducted. The presence of rodents around the pig farm and type of feed (use of uncooked waste food) were identified as associated risk factors for trichinellosis. Porcine trichinellosis occurred with a low rate of infection in this study.

“…One of the earliest reports of bear‐inflicted human trichinosis was a 1932 outbreak linked to consumption of bear jerky (Walker, ). Additional cases stemming from human consumption of bear meat have been reported across North America, as well as in Thailand (Clark et al, ; Doege et al, ; Dupouy‐Camet, Bourée, & Yera, ; Emson et al, ; Houzé et al, ; Hueffer, Parkinson, Gerlach, & Berner, ; McIntyre et al, ; Roselle et al, ; Schellenberg et al, ). Infected humans exhibit gastrointestinal symptoms, fatigue, rashes, fever and muscle pain.…”

“…While a few human case reports of bacterial infection following bear bites have been published, the vast majority of evidence of bear zoonoses in the literature concerns trichinosis/trichinellosis (Kunimoto, Rennie, Citron, & Goldstein, ; Lehtinen et al, ; Liu & Hsu, ; Thomas & Brook, ). Multiple cases of this nematode infection have been reported in humans consuming raw or undercooked bear meat throughout North America and South‐East Asia since the 1930s (Clark et al, ; Doege, Thienprasit, Headington, Pongprot, & Tarawanich, ; Emson, Baltzan, & Wiens, ; Harbottle, English, & Schultz, ; Houzé et al, ; McIntyre et al, ; Roselle, Schwartz, & Geer, ; Schellenberg et al, ; Walker, ). This review explores such well‐established zoonoses and potential zoonotic pathogens that have been reported in bear species and humans over the past century (Tables and ).…”

Captive and free-ranging wild bears can carry and transmit several zoonotic pathogens. A review of nearly 90 years of scientific publications concerning confirmed and potential zoonotic diseases that can be present in any of the eight species of bears in the world was conducted. The findings were organized amongst the following disease sections: bacterial, viral, protozoal, mycotic, helminth and arthropod-borne.The most commonly reported pathogens of concern were of parasitic (Trichinella, Toxoplasma) and bacterial (Francisella, Brucella) origin.
