“…All three Sarcocystis spp. showed a positive reaction of immunohistochemical staining towards the 15 kDa protein deemed responsible for the toxicity of S. fayeri [169], as already observed for S. sybillensis and S. wapiti isolated from venison in another Japanese work [170], cited in Ota et al [168]. Thus, the pathogenesis of the symptoms is still unclear, and further studies will be necessary to reveal if the 15-dalton protein is responsible for the enterotoxicity induced by Sarcocystis detected in venison [168].…”

“…Wildlife may harbor yet undiscovered zoonotic species for which people might serve as definitive hosts (following ingestion of sarcocysts) or even as accidental intermediate hosts (following ingestion of sporocysts) [132,166]. Recent outbreaks of "food poisoning" following consumption of Sarcocystis infected venison (deer) were described in Japan [168,169], suggesting a potential public health significance of Sarcocystis in cervids, which is so far poorly known [147]. In the first case, a 67-year-old Japanese man had eaten raw venison 4 h prior to the beginning of the symptoms (abdominal pain, vomiting, diarrhea and fever), which recovered in 24 h. Many white cysts containing bradyzoites, subsequently identified as S. truncata on the basis of the 18S rRNA, were found in venison meat [168].…”

“…Wildlife in particular may host still unknown zoonotic species for which people might act as definitive or as aberrant intermediate hosts [132,166]. Furthermore, the recent outbreaks of food intoxications after consumption of deer meat found to be infected with S. truncata in Japan [168,169], similar to those caused by toxins described in S. fayeri (typically associated to horse meat), suggest the need to further investigate also this aspect [147,168].…”

Game meat is increasingly appreciated and consumed in Europe, also due to the growing population of wild ungulates. In addition to interesting nutritional properties and market opportunities, game meat is characterized by some specific public health issues. This review focuses on the etiology, epidemiology, public health aspects and risk management along the supply chain, including parasite detection at slaughtering and inactivation in meat, of three selected foodborne parasitic hazards (Alaria alata, Toxoplasma gondii and Sarcocystis spp.) in the main mammalian game meat species in the EU: wild boar (Sus scrofa), red deer (Cervus elaphus), roe deer (Capreolus capreolus), fallow deer (Dama dama), Alpine chamois (Rupicapra rupicapra), moose (Alces alces), hare (Lepus europaeus) and wild rabbit (Oryctolagus cuniculus). The presented data point out the main issues, and knowledge gaps as well as the potential for improved control in order to contribute to the risk analysis process. To pursue an effective management of these parasitic zoonoses, awareness raising should involve all figures in the supply chain, including hunters, restaurateurs and consumers. Human behaviour and the lack of knowledge regarding meat borne parasitic zoonoses and the health risks they pose seem to be the most important factors responsible for human infections. However, detection methods, starting from the sampling procedure, should be further developed and standardized in order to improve the collection of accurate and up-to-date epidemiological data.

“…Ponadto, niedawno opisano zatrucia pokarmowe u ludzi, do których doszło po spożyciu mięsa jelenia wschodniego zarażonego Sarcocystis spp. w Japonii, co potwierdza, że mięso jeleniowatych może stanowić zagrożenie dla zdrowia publicznego związane z obecnością w nim tego pasożyta (5,40). W opisywanym przypadku 67-letni Japończyk skonsumował surowe mięso jelenia 4 h przed wystąpieniem objawów ze strony przewodu pokarmowego (bóle brzucha, wymioty, biegunka i gorączka).…”

The protozoa of the genus Sarcocystis are worldwide distributed parasites affecting a wide range of animals. They life cycle requires two hosts: definitive and intermediate. Over 250 species of Sarcocystis have been described but three of them are known to have a zoonotic potential. These are: S. hominis, S. heydorni and S. suihominis. Domestig pigs and wild boars can be intermediate hosts for S. suihominis, wheras cattle for S. hominis and S. heydorni. Therefore, people can become infected after eating raw or insufficiently heat-treated pork, wild boar meat or beef. Human sarcocystosis is generally asymptomatic but in some cases can induce the syptoms of intestinal illness. People can also become accidental intermediate hosts after ingesting sporocysts from feces-contaminated food or water leading to muscular sarcocystosis. The cysts of Sarcocystis spp. (sarcocysts), which with some exceptions, are not visible and therefore they are rarely detected during routine veterinary meat inspection consisting of visual assessment of muscle tissue and digestion (in case of examination of pig and wild boar meat). The presence of visible cysts of Sarcocystis spp. can lead to meat condemnation and it generates economic losses for farmers. Food safety regulations require the control of the parasites presence in meat intended for human consumption but there are no regulations regarding the control of Sarcocystis spp. Nevertheless, European Food Safety Authority (EFSA) encourage to monitor and characterise Sarcocystis ssp. in animal and foodstuffs.

“…Apart from affecting the health of infected cattle, S. cruzi is a potentially important cause of food poisoning. For instance, Sarcocystis -associated food poisoning cases have been reported in Japan following the consumption of raw Sarcocystis -infected Shika-deer meat [ 2 , 3 , 16 , 25 , 34 ]. In addition, the rabbit ileal loop test, a standard method for the measurement of enterotoxicity, has been reported to demonstrate the enterotoxicity of S. cruzi cyst extracts [ 30 ].…”

Sarcocystis cruzi is a member of the genus Sarcocystis, infecting bovine animals such as cattle and bison as intermediate hosts, and canids such as dogs and raccoon dogs as definitive hosts. Acute sarcocystosis of S. cruzi causes occasional symptoms in cattle, including weight loss, reduced milk production, abortions, and death, and similar to other Sarcocystis species can potentially cause food poisoning in humans when raw or undercooked infected cattle meat is consumed. Despite these issues, genetic information on S. cruzi is scarce, and there is no specific quantitative method for the detection and quantification of the parasite in infected cattle. In this study, we aimed to develop a method based on high-throughput sequencing of S. cruzi genome and transcriptome that specifically and quantitatively detects the S. cruzi acetyl-CoA synthetase gene (ScACS). Cardiac muscles were collected from slaughterhouses in Saitama Prefecture to obtain sarcocysts from which DNA and RNA were extracted for the high-throughput sequencing. Using the sequences, we developed a specific quantitative PCR assay which could distinguish S. cruzi ACS from that of Toxoplasma gondii by taking advantage of the differences in their exon/intron organizations and validated the assay with the microscopic counting of the S. cruzi bradyzoites. Thus, this assay will be useful for future studies of S. cruzi pathogenesis in cattle and for the surveillance of infected animals, thereby easing public health concerns.
