“…In general, the course and severity of human trichinellosis depends on the Trichinella species involved, the infective dose and the phase of the infection. Often, the infection is asymptomatic or connected only with mild symptoms [2,25]. Thus, the presence of antibodies in positive persons can signalise asymptomatic or former infection caused by low number of Trichinella spp.…”

Introduction. Trichinella spp. are zoonotic parasitic nematodes with almost worldwide distribution. The infection can be transmitted through the foodborne route and can cause serious health problems in infected human patients. It is also an economically important issue due to the high financial cost connected with prevention of the disease. Objective. The study aimed to discover trends in the epidemiological situation in people and animals in Slovakia in 2009-2018. Materials and method. Data on human trichinellosis originated from the Public Health Authority of the Slovak Republic, and data on Trichinella infection in animals from the State Veterinary and Food Administration of the Slovak Republic. A seroepidemiological study on 655 voluntary respondents was performed. Results. Altogether, 29 human cases were reported between 2009-2018, with a maximum of 13 cases in 2011. Males were affected more often (19 cases) than females (10 cases); the average age of patients was 45.1 years. Antibodies to Trichinella were detected in two sera (0.3%): in a serum from one hunter and one veterinarian. In the monitored period, the average prevalence of Trichinella infection was 9.6% in 2,295 red foxes, and 0.04% in 165,643 wild boars. Three (1.7%) of 178 surveyed brown bears were positive. Within the compulsory monitoring of trichinellosis in domestic pigs, none from a total of 1,632,688 pigs were positive. The presence of three species, Trichinella britovi, T. spiralis and T. pseudospiralis, was documented, with T. britovi representing 93.9% of identified isolates. Conclusions. The study indicates that the prevalence of Trichinella infection has not changed considerably with time in Slovakia, and the risk of human infection outbreaks is connected mainly with the consumption of wild boar meat.

“…Interestingly, larvae of T. britovi, i.e., the only species identified in Greece so far in free-ranging domestic pigs and in humans [14,15], and presumably, the dominant species in the area, show significant differences in abundance and life span in pig muscles, compared to T. spiralis [55]. It was shown that 2 months post infection (p.i.…”

“…In Greece, human trichinellosis was reported for the first time in 1946 [13]. Since then, the infection has been sporadically reported in humans and animals [14]. Epizootiological studies on trichinellosis in Greece are limited [15,16], leaving a significant gap in our knowledge on the frequency of parasitism in animals, as well as the species of parasites that are enzootic in the country.…”

Foodborne parasitic diseases represent a major threat to public health. Trichinellosis, caused by the nematode parasite Trichinella spp., is one of the most important foodborne diseases, while alariosis, caused by the trematode parasite Alaria spp., is less common in humans, and rare cases have been reported only in the USA and Canada. Both parasites can infect humans via the consumption of raw or undercooked wild boar meat. In order to investigate the prevalence of these parasites in wild boar meat in Greece, samples from the diaphragm pillars and the region of the mandibular angle from 128 wild boars, hunted in Greece, were collected. The samples were examined by classical parasitological (compression, artificial digestion, and Alaria spp. migration) and by molecular (real-time PCR) methods. For Trichinella spp. an existent real-time PCR detecting all species likely to be present in Greece was applied, while for Alaria spp. a real-time PCR was developed, employing an LNA TaqMan probe targeting the large subunit ribosomal RNA gene. All examined wild boar samples from Greece resulted negative for Trichinella and Alaria species, indicating a low prevalence of infection in the examined population. The novel real-time PCR for Alaria spp. has 81.5% amplification efficiency and is able to detect 0.12 larvae per 50 g of tissue and could be utilized as a complementary to AMT diagnostic tool in surveillance.

Summary In some countries, use of horsemeat as a food is inhibited by ethical and cultural concerns. However, horsemeat has potential health benefits, such as low fat and high unsaturated fatty acid content compared with other meats, as well as attractive sensory properties. Although there are many contradictory data on the dietary value in relation to human health, the effects of horsemeat have not been studied to a large extent. In this paper, we summarise existing knowledge on horsemeat quality and effects on human health. Our conclusion is that horsemeat may be consumed as a healthy alternative to other types of meat, provided that risks associated with microbial contamination during storage and possible presence of contaminants in horsemeat are taken into consideration. Future studies should evaluate the health‐promoting properties and safety of horsemeat and associated byproducts.
