“…In particular, T. britovi is the most common species within the Trichinella complex in wild ungulate populations in Central Italy and the most frequently isolated in human patients with trichinellosis from this area, showing a close epidemiological relation between Homo sapiens and Sus scrofa for Trichinella spp. diffusion in an ecosystem (Troiano and Nante, 2019 ). This is the result of a fascinating interconnection between host species’ and parasites’ ecological, biological, and ethological variables, intertwined together in an ecosystem scenario.…”

Trichinellosis is a globally diffused food-borne parasitic disease caused by nematodes of the Trichinella complex. During evolution, guided by ecological interactions, natural selection, and biochemical “intelligence”, these parasites developed admirable strategies to infect the host’s organism. One of the most fascinating is represented by the nurse cell formation in muscular tissue (e.g., diaphragm, skeletal muscle, extrinsic ocular muscles, etc.). This strategy allowed the parasite to adapt and conquer the wider host species spectrum, including ungulates and humans. Consumption of undercooked meat from infected wild ungulates constitutes the most important source of infection for the human species. In this study, we show the prevalence of Trichinella spp. in hunted wild boars (Sus scrofa) in Central Italy. During the hunting season 2021/2022 in the Province of Rieti, 554 wild boar diaphragm biopsies were collected for Trichinella spp. screening, in accordance with Regulation EU 1375/2015. An artificial digestion method was used for the detection of Trichinella spp. larval forms. The results revealed a positivity of 0.18% (1/554), and molecular biology identification demonstrated the presence of Trichinella britovi in the positive sample. This species is the most diffused in wild ungulate populations in Central Italy and the most frequently isolated in human patients with trichinellosis from this area, showing a close epidemiological relation between Homo sapiens and Sus scrofa for Trichinella spp. diffusion in an ecosystem. Epidemiological surveillance, in receptive animal species destined for human consumption and at any One Health level, represents the main “winning” strategy in the control of this worldwide, widespread food-borne parasitic disease.

“…Trichinosis is diagnosed mainly among hunters, their families, and friends. The main reasons for the identified cases are eating meat that was not subjected to veterinary control or appropriate culinary treatment [ 94 , 95 ]. The way of perceiving the safety of game depends on the level of nutritional knowledge, consumers’ experiences [ 60 ], and knowledge of the origin of the meat, which for consumers is a guarantee of safety [ 13 ].…”

Wild game meat can be a healthier, safer, and more environmentally friendly alternative to meat from farm animals. The aims of this study were to know the preferences and opinions of Polish consumers regarding game meat and its use in their diet, and to identify consumer segments based on differences in individual game meat choices, concerns, and eating habits related to game meat. The survey was conducted using the platform for online surveys among 1261 adult Poles. Six clusters characterizing the behavior of game consumers were identified (casual consumers, occasional game gourmets, indifferent consumers, occasional consumers, accidental consumers, wild game lovers) and four clusters among those who do not eat game (uninterested, restricted, dislikers, fearful). It has been found that wild game is more often eaten by hunters and their family or friends. The most common reasons for not consuming game are high prices, low availability, no family tradition, and unacceptable taste. Many positive respondents eat game because of its nutritional value but are concerned about the potential health risks and lack of cooking skills. The results of this study indicate the need for information programs for consumers about this meat. They will provide guidance to meat companies about consumer preferences for game and allow them to develop appropriate marketing strategies.

“…Although most trichinellosis in humans is caused by T. spiralis , some cases of T. britovi infection have recently been observed [ 54 , 55 , 56 , 57 ]. Furthermore, several papers have described the analysis of crude and excretory-secretory proteins characteristic of T. britovi [ 14 , 30 , 36 , 38 , 39 , 48 ].…”

Infection with Trichinella nematodes elicits non-specific and specific immune responses; these depend on the dose of infection, the nematode, and the host species. Few studies have examined the presence of specific antibodies against Trichinella spp. in the meat juice of wild animals. The aims of the study were to determine the prevalence of antibodies against Trichinella spp. in meat juice and to identify the specific proteins reacting with the meat juice from free-living carnivores naturally infected with the parasite. Meat juice samples were taken from foxes, badgers, raccoon dogs, and martens and tested with indirect ELISA. Antibodies against Trichinella spp. were detected in 10% of foxes and 46% of raccoon dogs. The ELISA results were confirmed by immunoblot, which revealed different protein patterns in meat juice from red foxes, raccoon dogs, and badgers. The most frequently observed bands were sent for further analysis by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) for the detection of Trichinella britovi immunogenic proteins. The results confirm the presence of proteins such as serine protease and heat shock proteins associated with Trichinella infection. These findings provide that meat juice is a useful matrix for proteomic analysis.
