“…Some countries of the world use the feces of livestock and even humans as an energy source, fertilizer, or incorporated into animal diets (SEMENAS et al, 1999;TOPP et al, 2009), and in the same way there are few regulations around the use of these wastewaters (KUNZ et al, 2009). Anaerobic digesters have been developed as an alternative to solve this problem (CRUZ et al, 2004).…”

Solid and liquid wastes from livestock operations represent important challenges for animal production regarding their impact in the environment and public health. Parasitological tests performed on 80 samples of affluent and effluent waters from three anaerobic biodigestors with flexible structure from swine farms of Caldas -Colombia, showed the presence of Isospora suis (45%), Eimeria suis (42.5%), E. espinosa (35%), Strongyloides ransomi (28.8%), E. perminuta (12.5%), E. cerdonis (3.8%), and E. porci (2.5%). The additional finding of eggs of Taenia spp. in 10% of the samples was probably caused by a connection between the human sewage system and the biodigester. Although we observed a mean decrease of 65.6% of parasites, these levels were insufficient to meet the minimum requirement set by Engelberg's guidelines regarding water quality. This study demonstrates the serious environmental impact that an inadequately treated animal wastewater represents, and has important implications for water resources and human health.Keywords: Wastewater, biodigestor, swine parasites, Taenia, Eimeria. ResumoResíduos sólidos e líquidos oriundos da suinocultura representam desafios importantes para a produção animal no que diz respeito ao impacto do meio ambiente e em saúde pública. Testes parasitológicos foram realizados em 80 amostras de águas afluentes e efluentes de três biodigestores anaeróbicos com estrutura flexível em granjas de Caldas -Colômbia, demonstrando a presença de Isospora suis (45%), Eimeria suis (42,5%), E. espinosa (35%), Strongyloides ransomi (28,8%), E. perminuta (12,5%), E. cerdonis (3,8%) e E. porci (2,5%). A constatação adicional de ovos de Taenia spp. em 10% das amostras foi provavelmente causada pela conexão entre o sistema de esgoto humano e o biodigestor. Embora fosse observada uma diminuição média de 65,6% dos parasitas, estes níveis são insuficientes para atender ao requisito mínimo estabelecido pelas diretrizes Engelberg em relação à qualidade da água. Este estudo demonstra o grave impacto ambiental que águas residuais animais inadequadamente tratadas representam, bem como as implicações nos recursos hídricos e na saúde humana.

Intestinal parasitic diseases are widely spread in the world, with the highest prevalence in developing countries. Children are mainly affected, showing a decrease in physical and mental development, as well as the expected manifestations of the disease. This situation can be greatly enhanced in children with poor nutritional status. The World Health Organization considers intestinal parasitic diseases a major cause of morbidity, closely linked to poverty and poor personal hygiene, inappropriate handling of raw food, lack of sanitation, lack of potable water supply, and environmental fecal contamination. Some parasitic diseases are cosmopolitan while others have variable geographic distribution, due to different factors such as the presence of exclusive intermediate hosts. In the past few years, globalization allowed the spread of certain parasites from endemic to non-endemic regions. Even though people's customs influence on the frequency of certain parasites, environmental conditions are a determinant factor for parasite survival. In our country, due to the variety of soils and climatic conditions, several causative agents of these parasitoses can be found. The aim of this work was to review the literature on the intestinal parasitic agents found in Argentina in human fecal samples and its environment, as parasitic contamination constitutes a direct indicator of the infection risk by intestinal parasites.
