Financial loss estimation of bovine fasciolosis in slaughtered cattle in South Africa
Parasite Epidemiology and Control
South Africa's livestock population is rapidly evolving and consequently will require sustained epidemiological surveillance to detect and prevent diseases which contribute to a decrease in livestock productivity, public health risk and food wastage. Fasciola infection is one of the commonest diseases affecting livestock health and a significant portion of meat and offal's are declared unfit for human consumption. This study assessed the prevalence and monetary losses associated with Fasciola infection at three abattoirs in Eastern Cape Province. A retrospective data of all slaughtered cattle were obtained from Department of Rural Development and Agrarian Reform (DRDAR) from 2010-2012. A prospective abattoir survey was conducted between July 2013 and June 2014 to determine the prevalence and financial loss due to fasciolosis. The highest prevalence was in December and January (23%) while the lowest prevalence was recorded in May and June (5%). Annual prevalence of Fasciola at abattoirs AB1, were (3.2%, 2.2% and 2.0%), AB2 (6.4%, 4.6% and 3.5%), AB3 (14.4%, 6.9% and 9.5%) for year 2010, 2011 and 2012 respectively. The total financial loss due to Fasciola infection during the active survey of the three abattoirs was ZAR 44, 930 (3456.2 USD). A breakdown of this figure shows that whole liver condemnation was ZAR 25, 230 (2, 357 USD), and partial liver condemnation was ZAR 19, 700 (1515.4 USD). The present study reveals the economic loss due to liver condemnation from Fasciola infection and provides regional baseline information regarding the prevalence of Fasciola in cattle at three abattoirs.

This study was conducted to report the prevalence of bovine fasciolosis and to estimate the direct economic losses (DEL) from condemnation of liver as a result of detection of lesions of fasciolosis in cattle slaughtered in Makurdi abattoirs. Retrospective data were collected from the abattoir records obtained from Ministry of Agriculture and Natural Resources (MANR) Makurdi, from 2008 to 2012. Direct economic losses were calculated based on a pilot study to determine the average price of liver per kilogram (AvP/kg) and using the formula: DEL = w × AvP/kg, where is the number of livers condemned and is the average liver weight in kg. Between 2008 and 2012, 64,978 cattle were slaughtered at Makurdi abattoirs, out of which 9,478 cattle were infected with Fasciola species. This represents an overall prevalence of 14.56% (95%, C.I.: 12.99-16.85%). Annual prevalence of bovine fasciolosis was significantly (P <0.05) high in 2010 and decreased from 2011 to 2012. During the late dry season, the prevalence of bovine fasciolosis was significantly high (P <0.05). A total of 4220 liver were condemned during the study period. This amounted to 12660 kg and valued at ₦12,660,000.00 ($79251.60 USD). The highest prevalence was recorded during the late dry season. However, cattle acquire the infection during the wet season and early dry season. Pathological lesions were much obvious during the late dry season possibly when the animals were most stressed, hence we suggest that control measures should be targeted towards wet and early dry seasons. Bovine fasciolosis is prevalent in cattle slaughtered in Makurdi abattoirs and accounts for huge financial losses.
Bovine fasciolosis is an economically important parasitic disease of cattle in tropical and subtropical countries responsible for considerable economic losses in the cattle industry, mainly through condemnation of fluke-infected liver. A cross sectional study was conducted between the periods of October, 2013 and March, 2014 to determine the prevalence and monetary losses associated with bovine fasciolosis, and comparing coprology and post mortem techniques for the examination among cattle slaughtered at Dangila municipal abattoir in Amhara region. Out of a total of 384 cattle examined, 85 (22.14%) and 116 (30.21%) were positive for fasciolosis through coprological and postmortem examinations, respectively. From this result, examination of liver of cattle during post mortem inspection was the most reliable method to detect fluke infection. F. hepatica was found to be the predominant Fasciola species in the study area with prevalence of 42.2% whereas F. gigantica, mixed, and immature...
Food animals are important sources of high quality protein and revenue to man, and can also serve as vehicles for disease transmission. Apart from economic losses, diseased organs in slaughtered cattle can also be sources of epidemiologic and zoonotic threats to man if not detected and controlled. The study was conducted to evaluate the number of cattle slaughtered, prevalence, seasonal variation, and socioeconomic consequence of bovine fasciolosis at the Ibadan Municipal abattoir, Ibadan, Oyo State, Nigeria, between 1994 and 2004 based on retrospective abattoir meat inspection records and a perspective meat inspection survey. Of the 1, 640,095 cattle slaughtered in 11 years, 37, 828 livers were condemned due to fasciolosis, translating into a prevalence of 2.31%. The incidence observed among males 172 (4.24%) was slightly higher than noted for females 452 (3.73%) though significant at 0.05 level of error. More so, the prevalence recorded in the dry season (October-March) was 19, 81...
Prevalence and Economic Impact of Bovine Fasciolosis at Kampala City Abattoir, Central Uganda
2015
Aim: This study was carried out to determine the prevalence of bovine fasciolosis in indigenous cattle slaughtered in Kampala City abattoir and to compare the diagnostic efficiency of fecal and post mortem examination. The study also assessed the economic impact of bovine fasciolosis associated with liver condemnation in the abattoir and weight loss to the animal. Methods: A cross sectional, experimental study of bovine fasciolosis was conducted using postmortem liver and fecal examination of slaughtered animals. A total of 511 slaughtered cattle were examined at post mortem and Fasciola species were recorded. The number of eggs per gram of feces was determined using the standard McMaster method (14). The formulae a+b+cto determine the total annual loss was used according to Ogunrinade and Adegoke 1982. Results: Of the 511 livers and fecal samples examined, 429(84%) and 358(70%) were positive for fasciolosis respectively. The most common Fasciola species affecting the cattle was F. gigantica (73.3%), followed by F. hepatica (5.68%). Mixed infections and unidentified or immature forms of Fasciola spp. were present in 0.59%, and 4.31% of cattle, respectively. The prevalence of fasciolosis recorded in this study was higher than that reported by other researchers in Uganda. The study also showed a strong relationship between fecal examination and postmortem findings of liver lesions though postmortem examination may be considered a better diagnostic tool forfasciolosis (k=213, P<0.05). Theabattoir lost a total of 231,186,550,000 Uganda shillings (92,474,620 US Dollars) annually on totally condemned liver. Conclusion: The prevalence of bovine fasciolosis amongst cattle slaughtered in Kampala City Trader's abattoir is high. Great economic losses as a result of condemnation of infected livers were incurred, and that F. gigantica is the main species of liver flukes affecting cattle in all districts of Uganda. Local climatic factors, cattle population and the presence of the snail intermediate hosts are probably the main drivers influencing the incidence of the disease in the various districts of the country. This disease therefore deserves serious attention by the various stakeholders in order to promote the beef industry in the study area in particular and in the country in general.
This study reports the prevalence of fasciolosis in slaughtered cattle at abattoirs of Ethiopia. A total of 761 cattle were randomly sampled and examined after slaughter of which 407 (53.48%) were positive for fasiolosis. Depending on the degree of pathological lesions, 110 (27.03%), 220 (54.05%), and 77 (18.92%), were lightly, moderately and severely affected respectively. There was a statistically significant association (P<0.05) between the degree of pathological lesion and number of flukes in the liver were 91, 73 and 18 mean number of flukes in moderately, severely and lightly affected livers. The result indicated Fasciola hepatica was more prevalent (45.20%) followed by Fasciola gigantica (26.54%); mixed infection (15.72%) and unidentified or immature fluke (12.53%). Statistically significant variation was also observed in the prevalence of fasciolosis among animals with poor (73.83%), medium (49.51%) and good (51.24%) body conditions (P<0.05). Coprological examinations on the 163 selected cattle at ante-mortem examination showed the prevalence rate of 8.94%. The total economic loss as a result of fasciola infestation was 3,003,488.1408 ETB equivalents. This study suggests that there was significant economic loss due to fasciolosis and warrant immediate attention.

Global journal of computer science and technology, 2018
A cross-sectional study was conducted to determine the abattoir prevalence of bovine fasciolosis and its economic importance in Robe Municipal Abattoir. A total of 502 cattle were randomly sampled and examined after slaughter. Out of 502 cattle examined at post mortem, 68.72% (345) were positive for fasciolosis. The prevalence of bovine fasciolosis was found to be significantly affected (P < 0.05) by the age of animal, in which young animals were affected than adult animals. The prevalence of bovine fasciolosis was also higher (P < 0.05) in poor body conditioned animals than good body conditioned animals. Sex of the animal was not found as a significant factor (p > 0.05) affecting the prevalence of disease. The prevalence of Fasciola hepatica was 238(68.98%) which was predominant among Fasciola species, causing bovine fasciolosis in the study areas. Whereas, the prevalence of Fasciola gigantica was 107 (31.02%). The economic significance of bovine fasciolosis was also asses...

Fasciolosis is a major zoonosis of ruminants which causes great economic losses to breeders. Given the economic and public health importance of this pathology, it is necessary to establish the current situation in a perspective of animal and ruminant meat consumer health protection. Therefore, the present study was conducted at the slaughterhouse of Dédougou in order to identify the species of fluke that caused this pathology in the Boucle du Mouhoun region and to estimate the prevalence, the risk factors and the economic losses associated with this pathology. For this purpose, 820 cattle and 6360 small ruminants were diagnosed through post-mortem examination over a five-month period from March to August 2018. Out of the 6360 small ruminant livers examined, no cases of infestation were observed unlike cattle in which the prevalence of infestation was 2.07%. These infestations were all due to Fasciola gigantica. Regarding the risk factors, a slight effect of the month and a high infl...
FASCIOLOSIS IN SLAUGHTERED CATTLE FROM ABATTOIRS IN ONDO STATE, NIGERIA
Vom Journal of Veterinary Science, 2012
Fasciolosis, an important helminth disease of livestock has been confirmed from abattoirs report in most parts of Nigeria for a long time. Prevalence of fasciolosis among slaughtered cattle in Ondo State, Nigeria was assessed. Abattoir records of slaughtered cattle were studied from 2003-2010. A total of 73,761 cattle were slaughtered within the study period. The study revealed 16.7% peak prevalence of fasciolosis from 13,206 cattle slaughtered in 2008. The 8 year study period recorded 14.5% prevalence. The high prevalence of fasciolosis translates to high economic loss due to liver damage and low carcass weight. The disease needs to be considered seriously as a great hindrance to livestock health and profitability; and also in regard to human health.
