    Financial loss estimation of bovine fasciolosis in slaughtered cattle in South Africa
    (2017) Jaja, Ishmael F.; Mushonga, Borden; Green, Ezekiel; Muchenje, Voster
    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

    Prevalence of bovine cysticercosis and age relationship at post-mortem in Nyagatare slaughterhouse
    (2015) Nzeyimana, Pie; Habarugira, Gervais; Udahemuka, Jean Claude; Mushonga, Borden; Tukei, Michael
    Bovine cysticercosis caused by the larval stage of the human tapeworm Taenia saginata is a zoonotic disease of great public health significance especially in developing countries. The present study was conducted on 291 slaughtered cattle at Nyagatare slaughterhouse in Eastern Rwanda between December 2013 and April 2014 to determine prevalence of bovine cysticercosis and its associated risk factors. Nine out of the 291 meat carcasses examined at postmortem were found to be infected with the parasite (3%). The infestation rate was higher in adult cattle than young cattle, where the highest prevalence (66.7%) was detected in older cattle 5 years and above followed by the carcasses of middle aged cattle of 3-5 years. The infestation was lowest in carcasses of cattle of young age (2-3 years). There was no significant difference (p>0.05) between breeds of slaughtered cattle, where out of 9 infected animals, 5 were from local breed and 4 were from crosses breed. On the other hand, the infestation rate was higher in female than male carcasses, but there is no significant variation was observed between sexes of cattle (p> 0.05). The infestation was mainly found in the heart muscles (35%, n=9), followed by masseter muscles (29.5%, n=9), tongue muscles (29.5%, n=9) and diaphragm muscles (6%, n=9). However, there was no significant difference (p>0.05) in the distribution rates of the cysticerci in the various organs of the cattle slaughtered at the abattoir.
