Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP); Conselho Nacional de Desenvolvimento Científico e Tecnológico (CNPq); Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES); Brazil is one of the most important countries in the production of animal source foods, and the consumers are looking for safe and innocuous products for health. In this context, it is necessary to prevent zoonosis that can be transmitted by animal source foods, which are sometimes consumed without proper cooking or made by vulnerable populations. On this review, important parasitic zoonotic diseases will be covered, which currently occur by this transmission route: toxoplasmosis, taeniasis-cysticercosis complex, cryptosporidiosis, anisakiasis, diphyllobothriasis and trichinosis.; O Brasil se destaca na produção mundial de alimentos de origem animal, sendo que cada vez mais os mercados consumidores buscam alimentos seguros e inócuos para a saúde. Nesse contexto, torna-se fundamental a prevenção das zoonoses, que podem ser transmitidas através dos alimentos de origem animal, que muitas vezes são consumidos sem o devido preparo ou por populações mais vulneráveis. Nesta revisão bibliográfica, serão abordadas importantes enfermidades parasitárias de caráter zoonótico que ocorrem atualmente pela via de transmissão alimentar: a toxoplasmose...

The advent of new technology for geographical representation and spatial analysis of databases from different sectors offers a new approach to planning and managing the control of tropical diseases. This article reviews the geographical and intersectoral aspects of the epidemiology and control of African trypanosomiasis, cutaneous and visceral leishmaniasis, Chagas disease, schistosomiasis, and foodborne trematode infections. The focal nature of their transmission, increasing recognition of the importance of animal reservoirs, and the need to understand environmental factors influencing their distribution are common to all these diseases. Geographical information systems (GIS) open a completely new perspective for intersectoral collaboration in adapting new technology to promote control of these diseases.

We investigated a small-scale serological survey to screen tissue-parasitic helminthiases of North Koreans as one of research programs for re-unification of Korea. Soil-transmitted helminthiases were found highly prevalent among North Korean residents at the border with China. ELISA using 4 tissue-parasitic helminth antigens was applied to 137 residents living in Cheongjin-shi, Hamgyeongbuk-do, North Korea and 133 female refugees in South Korea in 2004-2005. Among a total of 270 samples, 31 (11.5%), 25 (9.3%), and 11 (4.1%) were positive for specific IgG antibodies to antigens of Clonorchis sinensis, Taenia solium metacestode, and sparganum, respectively. The overall positive rate was 21.5%; 38.2% in males and 15.8% in females. The present finding suggests that tissue parasites, such as C. sinensis, T. solium metacestode and sparganum are highly prevalent in some limited areas of North Korea. These foodborne tissue-parasitic helminthiases should be considered for future control measures of parasitic diseases in North Korea.

Liver flukes belonging to the genus Fasciola are among the causes of foodborne diseases of parasitic etiology. These parasites cause significant public health problems and substantial economic losses to the livestock industry. Therefore, it is important to definitively characterize the Fasciola species. Current phenotypic techniques fail to reflect the full extent of the diversity of Fasciola spp. In this respect, the use of molecular techniques to identify and differentiate Fasciola spp. offer considerable advantages. The advent of a variety of molecular genetic techniques also provides a powerful method to elucidate many aspects of Fasciola biology, epidemiology, and genetics. However, the discriminatory power of these molecular methods varies, as does the speed and ease of performance and cost. There is a need for the development of new methods to identify the mechanisms underpinning the origin and maintenance of genetic variation within and among Fasciola populations. The increasing application of the current and new methods will yield a much improved understanding of Fasciola epidemiology and evolution as well as more effective means of parasite control. Herein, we provide an overview of the molecular techniques that are being used for the genetic characterization...

Anisakiasis, a human infection of Anisakis L3 larvae, is one of the common foodborne parasitic diseases in Korea. Studies on the identification of anisakid larvae have been performed in the country, but most of them have been focused on morphological identification of the larvae. In this study, we analyzed the molecular characteristics of 174 Anisakis type I larvae collected from 10 species of fish caught in 3 different sea areas in Korea. PCR-RFLP and sequence analyses of rDNA ITS and mtDNA cox1 revealed that the larvae showed interesting distribution patterns depending on fish species and geographical locations. Anisakis pegreffii was predominant in fish from the Yellow Sea and the South Sea. Meanwhile, both A. pegreffii and A. simplex sensu stricto (A. simplex s.str.) larvae were identified in fish from the East Sea, depending on fish species infected. These results suggested that A. pegreffii was primarily distributed in a diverse species of fish in 3 sea areas around Korea, but A. simplex s.str. was dominantly identified in Oncorhynchus spp. in the East Sea.

Cryptosporidium spp. e Giardia spp. são parasitos causadores de gastroenterites destacando se pela elevada incidência de casos, características de resistência aos tratamentos químicos e capacidade de permanência no meio ambiente. O importante papel desses protozoários em vários surtos epidêmicos de veiculação hídrica e alimentar coloca em evidência as hortaliças que, por serem ingeridas cruas, favorecem a aquisição destas parasitoses. No Brasil, são escassos os dados sobre a ocorrência destes protozoários em vegetais como alface e rúcula, alimentos frescos amplamente consumidos pela população. O propósito deste estudo foi investigar a ocorrência destes parasitos em amostras de hortaliças cultivadas na região agrícola de Campinas (SP), e comercializadas pela Central de Abastecimento de Campinas S.A. CEASA, avaliar a água utilizada na irrigação das mesmas, e as condições higiênico sanitárias das Unidades de Produção Agrícola UPAs estudadas (n=15). Para tanto, a presença de oocistos e cistos foi determinada em amostras de alface (Lactuca saliva) e rúcula (Eruca saliva) e parâmetros fisico químicos foram estabelecidos para a água de irrigação destes vegetais, em diferentes épocas do ano. As coletas foram realizadas durante dois anos consecutivos...

Illness and death from diseases caused by contaminated food are a constant threat to public health and a significant impediment to socio-economic development worldwide. To measure the global and regional burden of foodborne disease (FBD), the World Health Organization (WHO) established the Foodborne Disease Burden Epidemiology Reference Group (FERG), which here reports their first estimates of the incidence, mortality, and disease burden due to 31 foodborne hazards. We find that the global burden of FBD is comparable to those of the major infectious diseases, HIV/AIDS, malaria and tuberculosis. The most frequent causes of foodborne illness were diarrheal disease agents, particularly norovirus and Campylobacter spp. Diarrheal disease agents, especially non-typhoidal Salmonella enterica, were also responsible for the majority of deaths due to FBD. Other major causes of FBD deaths were Salmonella Typhi, Taenia solium and hepatitis A virus. The global burden of FBD caused by the 31 hazards in 2010 was 33 million Disability Adjusted Life Years (DALYs); children under five years old bore 40% of this burden. The 14 subregions, defined on the basis of child and adult mortality, had considerably different burdens of FBD, with the greatest falling on the subregions in Africa...
