    Assessment of beef microbial contamination at abattoir and retail meat shops in Morogoro Municipality, Tanzania
    (African Journal Online, 2014-11-19) Ntanga, P. D.; Mdegela, R. H.; Nonga, H. E.
    A cross section study was conducted in Morogoro Municipality to assess microbial contamination in beef production chain from abattoir to retail meat shops during February to May, 2012. Questionnaire on abattoir and meat shop hygiene was administered to 60 respondents. Meat, meat in-contact surface swab and water samples at the abattoir (n=36) and 14 meat shops (n=56) were analyzed for Total Viable Counts (TVC), Total Coliform Counts (TCC) and Total Faecal Coliform Counts (TFC). It was found that the respondents had not attended to any training on meat hygiene, had no protective gears and do not perform regular health examination. The infrastructure appeared obsolete. Carcasses and meat handling environment at abattoir and retail meat shops were in unhygienic condition. Water was scarce in the abattoir and meat shops. Water analysis showed heavy microbial contamination (mean TVC log 5.2±0.3). All the meat and meat in-contact surfaces were at different levels of microbial contamination and were beyond FAO recommendations. The mean TVC in meat was Log 7.2±1 cfu/g with the highest count (Log 7.24±1.3 cfu/g) recorded in samples from meat shops. The mean TVC on meat in-contact surfaces was Log 6±1.3 cfu/cm2 while mean TCC and TFC in meat were Log 6.1±1.6 and 5.9±1.7 cfu/g respectively. High microbiological loads in meat indicate gross contaminations along the whole meat value chain and pose potential risks for public health. Results obtained in this study provide information to the local government authorities and all stakeholders in the meat industry for proper management of the abattoir, retail meat shops and personnel; outlines key aspects for interventions and suggests future developments to prevent health risks associated with handling and consumption of contaminated meat.

    Assessment of causes of organ condemnations, financial losses and foetal wastage in cattle slaughtered at Bukoba Municipal abattoir, Kagera, Tanzania
    (African Journal Online, 2014-09-03) Msafiri, P. A.; Nonga, H. E.; Kassuku, A.
    Retrospective and prospective studies were carried out at Bukoba Municipal abattoir, Tanzania to identify causes of cattle organs condemnation and assess financial implications and magnitude of slaughter of pregnant cows and heifers. A retrospective study used data from 2011 to 2013 found that a total of 13,970 cattle were slaughtered and inspected. The prevalence of liver fasciolosis was 28.5%, lung congestion 10.2%, emphysema 5.1%, kidney haemorrhages 7.7% and hydronephrosis 4.3%. During a prospective study carried out in January 2014, post-mortem inspection of 692 cattle was done. The prevalence of liver fasciolosis was 37.6%, flabby heart 11.3%, emphysema 11.0% and lung congestion (6.6%). Value of condemned organs in one month of January 2014 was estimated to be Tanzanian shillings (TZS) 7,351 000 equivalent to US$ 4,595. Estimated total of TZS 6,174 600 (US$ 3,860) resulted from liver condemnations and TZS 6,092 400 (US$ 3,808) from liver fasciolosis which is 82.9% of the total financial losses. Of all the 480 cows and heifers slaughtered, 75 (15.6%) were found to be pregnant. The high condemnation rates led to financial losses and some of the conditions are of zoonotic importance. The indiscriminate slaughter of pregnant animals is against animal welfare. Therefore, diseases surveillance and control measures need to be strengthened, and enforcement of legislation governing animal welfare to curb the slaughter of pregnant animals.

    Prevalence and financial losses associated with Bovine fasciolosis at SAAFI and Sumbawanga municipal abattoirs, Rukwa, Tanzania
    (African Journal Online, 2013-05-15) Kamwela, K.M.; Kassuku, A. A.; Nonga, H. E.
    This study was conducted to determine the prevalence and financial losses of Bovine fasciolosis at SAAFI and Sumbawanga municipal abattoirs. Primary data was collected for one month (November/December 2012) through meat inspection. Secondary data was retrieved from the abattoir records for the period of five years (January 2008 to December 2012). During the one month of prospective study period, a total of 677 cattle were slaughtered at SAAFI abattoir and 45.4% of the livers were condemned due to fasciolosis. At Sumbawanga municipal abattoir 594 cattle were slaughtered, 47.1% of the livers were also condemned due to fasciolosis. The overall prevalence of fasciolosis for five years at SAAFI abattoir was 26.5% (10 592 cattle slaughtered and 2 801 livers were condemned due to fasciolosis) while that of Sumbawanga municipal abattoir was 16.4% (23 612 cattle slaughtered and 3 862 livers were condemned due to fasciolosis). Fasciola gigantica was found to be the liver fluke species affecting cattle slaughtered in Rukwa region. The one month (November/December) financial loss due to liver condemnation (Fasciola infected) was Tanzania shilings (TZS) 5 894 400 (USD 3 497) and TZS 5 376 000 (USD 3 190) for SAAFI and Sumbawanga municipal abattoirs, respectively. The public health implication on the quantity of infected livers condemned and the losses incured by livestock and meat traders warrants for more extensive epidemiological investigations to determine the magnitude of the problem in live animals and institution of proper control strategies of fasciolosis in the study area

    Sanitary practices and occurrence of zoonotic conditions in cattle at slaughter in Morogoro municipality, Tanzania: implications for public health
    (Tanzania Journal of Health Research, 2012-04) Komba, Erick V.G; Komba, Ewaldo V; Mkupasi, Ernatus M; Mbyuzi, Albano O; Luwumba, Denice; Busagwe, Zablon; Mzula, Alexanda
    As meat consumption is increasing worldwide to cover for protein demands, also raise concerns and challenges regarding meat hygiene and safety. The current one year follow up study aimed at investigating on sanitary practices and occurrence of zoonotic conditions, during post- mortem examination, in cattle at slaughter in Morogoro Municipality abattoir. Sanitary practices were assessed through direct observation where as routine post-mortem inspection procedures were employed to detect zoonotic conditions in cattle at slaughter. During the study period a total of 30,713 cattle were slaughtered and inspected at the abattoir. Results revealed poor hygienic practices at the level of abattoir surrounding, the slaughter operation area, personnel as well as meat vans. Whole carcasses, lungs, livers, hearts and heads were condemned due to zoonotic conditions at rates of 0.026%, 1.96%, 1.61%, 0.02% and 0.21% respectively. Bovine tuberculosis, Cysticercus bovis cysts, fasciolosis and hydatidosis were the responsible zoonotic conditions for the condemnations. Bovine tuberculosis was a leading zoonotic cause of condemnations accounting for 95.7% of lungs and 100% of all head and carcass condemnations. Cysticercus bovis cysts were ranking the second in serving as causes of condemnations closely followed by fasciolosis and lastly hydatidosis. Occurrence of disease conditions with zoonotic implication in cattle at slaughter, meant for human consumption, may pose significant economic and public health risks to especially disaster-prone marginalized communities. Thus, there is a need to introduce appropriate control measures of livestock diseases to minimize the rate of infection; and eventually reduce economic losses and safeguard public health. _____________________________________________________________________________
