“…0.013-0.014) is lower than other established in several other Brazilian states, such as São Paulo (2.92%), Minas Gerais (1.81%), Goiás (0.71%), Mato Grosso do Sul (1.11%) (Rossi et al 2015), Paraná (2.23%) (Guimarães-Peixoto et al 2012), Espiríto Santo (1.02%) (Avelar et al 2016) and Mato Grosso (0.0873%) (Rossi et al 2016). Other paper published regarding bovine cysticercosis prevalence in the same state, showed a prevalence of 0.07% (4,420/6,239,172) through the years 2007 to 2010 (Dutra et al 2012), enforcing the theory that a reduction in the prevalence might be ongoing in this state.…”

“…Among the identified risk factors, the most important were cattle herds' access to contaminated water sources, presence of fishing activities near grazing areas (Rossi et al 2015); contaminated feed sources (Jenkins et al 2013), organic production systems (Calvo-Artavia et al 2013a), use of sewage sludge to irrigate pasture (Cabaret et al 2002) and proximity to densely populated areas (Rossi et al 2016).…”

This study focused on assessing the prevalence, geospatial distribution and risk factors for bovine cysticercosis in cattle from the state of Rondônia, Brazil, through the years 2012 to 2015. The prevalence established was 0.014% (95% C.I. 0.013-0.014), with a higher detection of unviable cysticerci (84.80%). The municipalities of Itapuã do Oeste, Candeias do Jamari, Nova Brasilândia D’Oeste, Pimenteiras do Oeste, Porto Velho, Nova Mamoré, Urupá and Guajará-Mirim had higher risk (OR>1; p<0.05) for cysticercosis occurrence compared with the municipality of Castanheiras (OR=1). The Administrative Regions of Porto Velho, Guajará-Mirim, Colorado D’Oeste, Cacoal, Ji-Paraná had higher risk (OR>1; p<0.05) for cysticercosis occurrence in the slaughtered animals than those reared in Ariquemes Administrative Region (OR=1). Some variables such as human population density (OR=2.15; 2.15-2.16), percentage of urban houses with inappropriate sewage system (OR=1.91, 1.91-.1.92) and percentage of inappropriate rural sewage system (OR=1.14, 1.14-1.14) were significantly associated (p<0.05) with the occurrence of bovine cysticercosis. In conclusion, the prevalence of bovine cysticercosis in the state of Rondônia was 0.014% (95% C.I. 0.013-0.014) and higher-risk areas were identified, providing useful information to Official Sanitary Inspection System in order to improve cysticercosis detection. Also, human population density and the lack of appropriate sewage system in urban and rural areas are closely related to bovine cysticercosis occurrence in this state.

“…Bovine cysticercosis is prevalent in many Brazilian regions and is highly related to regional basic sanitary condition and cattle management (Rossi et al 2015). The initial prevalence observed at the farm (24.9%) was higher than the prevalence reported by other authors for the same state (1.0 to 6.3%) (Schenk & Schenk 1982, Carmo & Oliveira 1997, Marques et al 2008, Rossi et al 2015. However, after the implementation of proper control measures, the prevalence decreased to percentages comparable to the ones reported for the Mato Grosso do Sul State, indicating success for the adopted strategy.…”

“…The taeniasis-cysticercosis complex is also a widespread public health issue often associated to sanitary problems, poor hygiene habits and consumption of raw or undercooked beef (Lloyd 2014). Common factors contributing to this universal distribution include the parasite eggs spreading by human feces together with their high survival periods in the environment, poor sewage treatment, grazing farm systems, contamination of water sources by human waste and deficient meat inspection protocols (Dorny & Praet 2007, Rossi et al 2015.…”

Animal movement network analysis as a tool to map farms serving as contamination source in cattle cysticercosis

et al. 2017

Bovine cysticercosis is a problem distributed worldwide that result in economic losses mainly due to the condemnation of infected carcasses. One of the difficulties in applying control measures is the identification of the source of infection, especially because cattle are typically acquired from multiple farms. Here, we tested the utility of an animal movement network constructed with data from a farm that acquires cattle from several other different farms to map the major contributors of cysticercosis propagation. Additionally, based on the results of the network analysis, we deployed a sanitary management and drug treatment scheme to decrease cysticercosis’ occurrence in the farm. Six farms that had commercial trades were identified by the animal movement network and characterized as the main contributors to the occurrence of cysticercosis in the studied farm. The identification of farms with a putative risk of Taenia saginata infection using the animal movement network along with the proper sanitary management and drug treatment resulted in a gradual decrease in cysticercosis prevalence, from 25% in 2010 to 3.7% in 2011 and 1.8% in 2012. These results suggest that the animal movement network can contribute towards controlling bovine cysticercosis, thus minimizing economic losses and preventing human taeniasis.

S U M M A R YThis study aimed to assess the prevalence and spatial distribution of bovine cysticercosis in the state of Goiás, Brazil; to verify its association with epidemiological variables, and to establish the economical losses for beef farms. A set of 23 255 979 bovines from 246 municipalities were slaughtered from 2007 through 2014. The prevalence of bovine cysticercosis was 0·53% [95% confidence interval (95% CI) 0·5295-0·5354]. The Central mesoregion showed a higher risk [odds ratio (OR) = 4·44; 95% CI 4·2936-4·5895] for detecting infected animals with cysticerci compared with those raised at North and Northeast mesoregion (OR = 1·02 and OR = 1·02). The microregion of Goiânia had a higher risk for bovine cysticercosis occurrence (OR = 11·05, 95% CI 10·6933-11·4099) compared with the microregion of São Miguel do Araguaia (OR = 1). None of the epidemiological variables evaluated in this study was significantly associated (P > 0·05) with bovine cysticercosis prevalence.In conclusion, the prevalence of bovine cysticercosis in the state of Goiás, Brazil, was 0·53% and some mesoregions and microregions presented a higher risk for its occurrence. The economical losses due to its occurrence during the period ranged from US$9 260 728·57 to 11 313 816·67. These results highlighted the needs of adopting prophylactic measures and the development of political strategies in specific regions in order to control this zoonose and reduce the economical losses for beef production chain and the costs for public health.
