Introduction: Helminth infections of livestock can result in considerable economic losses. This study aims to evaluate the spatial frequency of cystic echinococcosis (CE), dicrocoeliasis, and fascioliasis in livestock slaughtered in Iran during the years 2015-2019 and estimate direct costs associated with organ condemnation due to these parasites.Methods: Abattoir data from all 31 Iranian provinces were collected from the Iran Veterinary Organization. Infection prevalence was calculated per year at the province level. The Local Moran's I statistic was performed to evaluate spatial autocorrelation of animals positive at slaughter for the years 2015-2019. Direct costs associated with condemned livers were calculated for each parasitic condition. Results: Overall prevalence values for the study timeframe were as follows: sheep and goat fascioliasis (1.5%, 910,282/58,393,349), cattle fascioliasis (3.8%, 23,3175/6,038,419), sheep and goat dicrocoeliasis (4.6%; 270,1274/58,393,349), cattle dicrocoeliasis (3.1%; 186,009/6,038,419), sheep and goat CE (5.3%; 3,108,767/58,393,349), and cattle CE (7.2%; 438,534/6,038,419). Northwestern Iran had the highest prevalence of CE and fascioliasis. High infection areas for Dicrocoelium spp. included the provinces of Zanjan, Gilan, Qazvin, and Tehran, which are located in northern Iran. Direct economic losses for sheep and goat fascioliasis, dicrocoeliasis, and CE for the study period were US$13,841,826, US$41,768,472, and US$22,801,296, respectively. Direct economic losses for cattle fascioliasis, dicrocoeliasis, and CE for the study period were US$1,989,582, US$1,669,289, and US$2,656,535, respectively.Conclusion: Our findings provide valuable data for future monitoring of these important parasitic diseases in Iranian livestock. Disease control strategies are required to reduce the economic and public health impact of these helminths.

“…E. granulosus , Fasciola spp., and D. dendriticum are significant helminthic zoonoses [ 23 , 24 ]. These parasites have considerable medical, veterinary, and economic complication worldwide [ 11 , 22 , 25 ]. Iran is an important endemic focus of hydatidosis and liver flukes [ 8 , 12 , 13 , 23 , 26 - 28 ].…”

“…There has been a positive relationship between the frequency of these parasites in animals and the possibility of human infection [ 34 ]. Therefore, this alarming frequency of E. granulosus , Fasciola spp., and D. dendriticum in animals represents a potential hazard for human beings [ 23 , 25 ]. Based on the literature, the prevalence of fasciolosis, dicrocoeliosis, hydatidosis of sheep, and hydatidosis of cattle in various parts of Iran ranged from 2.3% to 5.5%, 2.5% to 4.8%, 1% to 27.5%, and 1% to 28.5%, respectively [ 32 , 35 ].…”

“…Based on inspection of the internal organs from abattoirs, the infection rate of hydatidosis was as in Kashan, Iran (sheep 2.25% and cattle 4%), Ardabil, Iran (sheep 74.4% and cattle 38.3%), Khorasan, Iran (sheep 2.65% and cattle 4.15%), Lorestan, Iran (sheep 21.22% and cattle 26.71%), Shiraz, Iran (sheep 45.52% and cattle 11.6%), Torbat-E-Heidarieh, Iran (sheep 7.95% and cattle 8.05%), and Kermanshah, Iran (sheep 3% and cattle 7.65%) [ 11 , 19 , 22 , 27 , 37 - 39 ]. The differences in frequency of hydatid cyst in various investigations are due to culture, geographical parameters, climate changes, environmental conditions, livestock husbandry, type of population of final hosts and sample collection [ 11 , 23 , 25 ]. Various frequencies of fasciolosis have previously been reported from the different parts of Iran, including 5.3% in sheep and 25.9% in cattle in Ardabil, 2.49% in sheep and 1.86% in cattle in Shiraz, 1.93% in sheep and 1.89% in cattle in Torbat-E-Heidarieh, and 1.23% in sheep and 5.99% in cattle in Kermanshah [ 11 , 22 , 23 , 27 ], and the frequency rate of dicrocoeliosis regarding abattoirs data in the different regions of Iran is as follows: Ardabil (sheep 6.8% and cattle 10.6%), Shiraz (sheep 0.026% and cattle 0.91%), Torbat-E-Heidarieh (sheep 1.97% and cattle 2.16%), and Kermanshah (sheep 2.33% and cattle 4.81%) [ 11 , 22 , 23 , 27 ].…”

Background and Aim:Cystic echinococcosis, Echinococcus granulosus, and liver flukes, such as Fasciola spp. and Dicrocoelium dendriticum, are important parasitic zoonoses, where they able to cause significant veterinary, medical, and economic problems. The present study was carried out to obtain the updated knowledge on the frequency of hydatidosis, fasciolosis, and dicrocoeliosis in the slaughtered sheep and cattle.Materials and Methods:Information were collected from meat inspection records using systematically visual inspection, palpation, and incision of the visceral organs in the industrial abattoir in Tehran, the capital of Iran, between February 1, 2015, and January 31, 2018. For an analysis of the data, SPSS version 16 was applied.Results:The hydatidosis infection in sheep and cattle was 2.48% and 2.25%, respectively. With respect to liver flukes, 0.62% and 0.25% sheep and cattle were infected by Fasciola spp., respectively; furthermore, 2.86% sheep and 0.79% cattle were positive for D. dendriticum.Conclusion:The findings will provide considerable awareness for the future monitoring and control of these potentially important infections.

Aim:Fasciolosis and dicrocoeliosis are important parasitic diseases worldwide, causing significant financial losses due to decrease in production and viscera condemnation in animals. We performed the current research to assess the epidemiology of these infections and determine their significance from an economic perspective in Arak, Iran.Materials and Methods:In total, we evaluated 118,463 sheep, 207,652 goats, and 43,675 cattle through necropsic analysis at the slaughterhouses. The average weight of sheep, goat, and cattle liver was 1000, 900, and 5000 g, respectively. The average price of liver in the market was 8 USD/kg. Moreover, the elimination of fundamental nutrients and vitamins was evaluated in infected livers. The prevalence of fasciolosis and dicrocoeliosis was determined. Analysis of variance test was applied for the statistical analysis, and the significance level was <0.05.Results:In total, Fasciola hepatica and Dicrocoelium dendriticum were detected in 0.56% (confidence interval CI, 0.54-0.59) and 0.77% (CI, 0.75-0.81) of the animals, respectively (p=0.1). The annual economic loss attributed to fasciolosis and dicrocoeliosis was 26698.4 and 30479.2 USD, respectively. The total economic loss was 10,880, 9079.2, and 10,520 dollars in sheep, cattle, and goats, respectively. On the other hand, financial loss resulting from fasciolosis was 7160, 6098.4, and 13,440 dollars in sheep, goats, and cattle, respectively. In addition, economic loss due to dicroceliasis was 10,880, 9079.2, and 10,520 dollars, respectively.Conclusion:Overall, fasciolosis and dicrocoeliosis in Iran always remain common in sheep, goats, and cattle that afford major economic loss of all the country also exist in Arak province. The present study could provide basic information for further examination of liver fluke infections in Iran.
