The objectives of this study were to (1) evaluate the liver damage and carcass weight of cattle naturally infected with<jats:italic>Fasciola hepatica<\/jats:italic>from the state of Rio Grande do Sul (RS), Brazil, and to (2) determine the distribution of adult flukes in 12,236 cattle liver from RS. The data from these experiments were used to calculate the overall economic loss due to<jats:italic>F. hepatica<\/jats:italic>infection. Eighteen adult Polled Hereford cows were divided into a triclabendazole (TbG) and a<jats:italic>F. hepatica<\/jats:italic>-positive group (FhG). For Experiment 1, a generalized linear mixed model revealed a statistical difference in carcass weight (49.8 kg) between TbG and FhG. The Monte Carlo analysis also revealed that the animals\u2019 weight differences were due to the disease. For Experiment 2, the prevalence of infected livers was above 16% (1904\/12,236), mostly (20.1%) from the south-west region of RS. The Susceptible-infected-recovered (SIR) epidemic model revealed the evolution of the infection using a high infectivity and low recovery rate. Other distinctive scenarios that occur in RS were also established with different rates of infectivity. The economic assessment showed a potential loss of US$45 million to the beef cattle industry of RS, with an overall State cost of US$90.3 million. These novel findings reveal the importance of fasciolosis infection, which can cause a significant health condition and poor animal welfare.<\/jats:p>","DOI":"10.1017\/s0022149x2000067x","type":"journal-article","created":{"date-parts":[[2020,9,10]],"date-time":"2020-09-10T06:50:09Z","timestamp":1599720609000},"source":"Crossref","is-referenced-by-count":10,"title":["<i>Fasciola hepatica<\/i>infection in cattle and the use of simulation models for endemic areas"],"prefix":"10.1017","volume":"94","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0572-5628","authenticated-orcid":false,"given":"M.B.","family":"Molento","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9001-6625","authenticated-orcid":false,"given":"L.H.","family":"Dutra","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8225-0374","authenticated-orcid":false,"given":"I.C.","family":"Pritsch","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2865-9785","authenticated-orcid":false,"given":"V.P.","family":"Garbin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.M.","family":"Pereira","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.","family":"Gavi\u00e3o","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A.L.","family":"Gabriel","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6491-9302","authenticated-orcid":false,"given":"R.S.","family":"de Sousa","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8400-3166","authenticated-orcid":false,"given":"J.G.A.","family":"Viana","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"56","published-online":{"date-parts":[[2020,9,10]]},"reference":[{"key":"S0022149X2000067X_ref42","doi-asserted-by":"publisher","DOI":"10.2478\/s11686-018-00013-9"},{"key":"S0022149X2000067X_ref41","first-page":"186","article-title":"An evaluation of the economic losses resulting from condemnation of cattle livers and loss of carcass weight due to Fasciolosis: a case study from Hai town abattoir, Kilimanjaro region, Tanzania","volume":"21","author":"Swai","year":"2009","journal-title":"Livestock Research and Rural Development"},{"key":"S0022149X2000067X_ref40","first-page":"e008520","article-title":"Correlation between climate data and land altitude for Fasciola hepatica infection in cattle in Santa Catarina, Brazil","volume":"29","author":"Silva","year":"2020","journal-title":"Brazilian Journal of Veterinary Parasitology"},{"key":"S0022149X2000067X_ref39","doi-asserted-by":"publisher","DOI":"10.1016\/j.vetpar.2015.12.021"},{"key":"S0022149X2000067X_ref38","doi-asserted-by":"publisher","DOI":"10.1136\/vr.157.7.188"},{"key":"S0022149X2000067X_ref43","first-page":"113","volume-title":"Fasciolosis","author":"Torgerson","year":"1999"},{"key":"S0022149X2000067X_ref37","first-page":"13","article-title":"The economics of Fasciola hepatica infections in cattle","volume":"126","author":"Ross","year":"1970","journal-title":"British Veterinary Journal"},{"key":"S0022149X2000067X_ref35","first-page":"145","article-title":"Strategic control and prevalence of Fasciola hepatica in Cajamarca","volume":"7","author":"Raunelli","year":"2009","journal-title":"Peru: A pilot study.
