Trichinellosis is a rare parasitic zoonosis caused by Trichinella following ingestion of raw or undercooked meat containing Trichinella larvae. In the past five years, there has been a sharp decrease in human trichinellosis incidence rates in the European Union due to better practices in rearing domestic animals and control measures in slaughterhouses. In November 2014, a large outbreak of trichinellosis occurred in Belgium, related to the consumption of imported wild boar meat. After a swift local public health response, 16 cases were identified and diagnosed with trichinellosis. Of the 16 cases, six were female. The diagnosis was confirmed by serology or the presence of larvae in the patients’ muscle biopsies by histology and/or PCR. The ensuing investigation traced the wild boar meat back to Spain. Several batches of imported wild boar meat were recalled but tested negative. The public health investigation allowed us to identify clustered undiagnosed cases. Early warning alerts and a coordinated response remain indispensable at a European level.

“…The migratory flow of humans with their own food practices including the consumption of raw meat, the illegal importation of not-controlled meat from endemic to nonendemic countries, and new food practices and dishes including raw meat resulted in outbreaks in Denmark, Germany, Italy, Spain, and the United Kingdom (45,101,124,154). The increasing number of international travelers has resulted in many reports of tourists who acquired Trichinella infections while traveling or hunting in areas of endemicity and subsequently developed disease after their return to their home countries.…”

SUMMARY Throughout much of the world, Trichinella spp. are found to be the causative agents of human trichinellosis, a disease that not only is a public health hazard by affecting human patients but also represents an economic problem in porcine animal production and food safety. Due to the predominantly zoonotic importance of infection, the main efforts in many countries have focused on the control of Trichinella or the elimination of Trichinella from the food chain. The most important source of human infection worldwide is the domestic pig, but, e.g., in Europe, meats of horses and wild boars have played a significant role during outbreaks within the past 3 decades. Infection of humans occurs with the ingestion of Trichinella larvae that are encysted in muscle tissue of domestic or wild animal meat. Early clinical diagnosis of trichinellosis is rather difficult because pathognomonic signs or symptoms are lacking. Subsequent chronic forms of the disease are not easy to diagnose, irrespective of parameters including clinical findings, laboratory findings (nonspecific laboratory parameters such as eosinophilia, muscle enzymes, and serology), and epidemiological investigations. New regulations laying down rules for official controls for Trichinella in meat in order to improve food safety for consumers have recently been released in Europe. The evidence that the disease can be monitored and to some extent controlled with a rigorous reporting and testing system in place should be motivation to expand appropriate programs worldwide.

“…However, the Muslim population is not exempt from acquiring trichinellosis as exemplified by several outbreaks derived either from minced beef illegally mixed with pork of unknown origin, or from wild boars in Turkey (Akkoc et al, 2009;Pozio, unpublished data). Also, it should be noted that immigration of populations with ethnic food practices such as the consumption of raw meat and the illegal importation of uncontrolled meat products have resulted in new outbreaks in countries where Trichinella is considered non-endemic in the commercial pork market i.e., Denmark, Germany, Italy, Spain, Switzerland and the United Kingdom (Pozio and Marucci, 2003;Gallardo et al, 2007;Nöckler et al, 2007;Stensvold et al, 2007;Lozano Becera et al, 2012). Confusing matters further, reports of outbreaks in non-endemic areas are on the rise due to international tourists who acquired Trichinella infections abroad or hunting in areas of endemicity but who did not developed disease symptoms until returning to their home countries.…”

Contrary to our understanding of just a few decades ago, the genus Trichinella now consists of a complex assemblage of no less than nine different species and three additional genotypes whose taxonomic status remains in flux. New data and methodologies have allowed advancements in detection and differentiation at the population level which in turn have demonstrably advanced epidemiological, immunological and genetic investigations. In like manner, molecular and genetic studies have permitted us to hypothesise biohistorical events leading to the worldwide dissemination of this genus, and to begin crystalising the evolution of Trichinella on a macro scale. The identification of species in countries and continents otherwise considered Trichinella-free has raised questions regarding host adaptation and associations, and advanced important findings on the biogeographical histories of its members. Using past reviews as a backdrop, we have ventured to present an up-to-date assessment of the taxonomy, phylogenetic relationships and epidemiology of the genus Trichinella with additional insights on host species, survival strategies in nature and the shortcomings of our current understanding of the epidemiology of the genus. In addition, we have begun compiling information available to date on genomics, proteomics, transcriptomics and population studies of consequence in the hope we can build on this in years to come.

Outbreak of trichinellosis in Spain and Sweden due to consumption of wild boar meat contaminated with Trichinella britovi

Abstract: Early this year, 21 people became ill with trichinellosis in both Spain and Sweden. This was traced to consumption of home-made wild boar sausage from an original source in Spain.
