    Causes and implications of bovine organs/offal condemnations in some abattoirs in Western Nigeria.
    (2009) CADMUS, S.I.B.; ADESOKAN, H.K
    Food animals though sources of protein and revenue to man, also serve as vehicles of disease transmission. This work reviews a three year record of slaughtered cattle in 12 abattoirs/slaughter slabs in western Nigeria to determine the economic and public health issues associated with their disease conditions. Out of 641,224 cattle slaughtered, 51,196 (7.98%) were attributable to 14 diseases/conditions including tuberculosis, pneumonia, fascioliasis, pimply gut, paramphistomosis, cysticercosis, dermatophilosis, tonsillitis, taeniasis, ascariosis, abscess, mange, mastitis and immature fetuses. Pneumonia (21.38%), fascioliasis (20.28%) and tuberculosis (7.95%) were major reasons for condemnations; least being ascariosis (0.01%). The lungs (45.66%) and liver (32.94%) accounted for most organ condemned while the heart (0.02%) was the least affected. The proportions of pneumonia, fascioliasis and immature fetuses observed were not statistically different (Mean = 3895.7; 3654.0; 3467.3); however, asignificant difference existed with other conditions (MeanA = 3895.7; 3654.0; 3467.3; MeanB = 1359.7; 1057.7; 510.3). Organs/offal condemnations constituted loss of revenue and animal protein as 124,333 kilo kilogrammes worth of meat valued in Naira at N41,613,043 ($332,904) was lost over the period giving an average of N13,871,014 ($110,968) annually. This, coupledwith fetal wastage represented an economic loss; with associated public health implications.

    Actualization of strategies for beef quality control in south western Nigeria
    (2005-06) Olugasa, B. O.; Cadmus, S.I. B.; Atsanda, N.N.
    A major private abattoir wd meat processing plant in south-westem Nigeria was studied in this article to determine its compliance with control over dissemination of parasitic and microbial diseases from beef to man. To ensure total quality control, a private veterinarian sourced for cattle on farms and supplied these to the abattoir. In addition, a public health veterinarian in government service at the abattoir carried out antemortem tests, postmortem inspection and removal of unwholesome cattle. Diseases such as fascioliasis, tuberculosis, cysticercosis and brucellosis were effectively controlled in this way. Hence, United African Company (UAC) Foods provides wholesome beef to the community

    A comparative study of three methods for detecting Fasciola infections in Nigerian cattle
    (VETERINARSKIARHIV, 2008) Adedokun, O. A.; Ayinmode, A. B.; Fagbemi, B. O.
    Qualitative examination of Fasciola gigantica eggs in faeces and bile were compared with the detection of precipitating antibodies in sera by agar gel precipitation test (AGPT) in 1000 cattle slaughtered at the Bodija municipal abattoir in Ibadan, Nigeria. Faecal and bile examination methods detected (196) 33.5% and (389) 38.9% of the animals as positive for fasciolosis, while (474) 47.4% were positive by AGPT. Both direct bile examination and faecal egg detection methods have high specificity and positive predictive value (100%) when compared with AGPT. However, lower values for sensitivity and negative predictive value were observed for both faecal egg examination (66.5% and 67.9% respectively) and bile examination (81.0% and 78.9% respectively). Fecal and bile examination failed to detect 33.5% and 19.0% of the cases detected by AGPT. The results of this study revealed that the AGPT could become a better test for the herd diagnosis of bovine fasciolosis for veterinarians and other investigators in Nigeria.
