“…The unsupervised irrigation fields often flooded with water promotes the proliferation of the infectious larval stages of the parasite. There are several studies [11,30,52] that support the findings of this study, others [9,53,54] reported a higher rate of condemnation due to fasciolosis.…”

“…Grossly, it is an enlarged palpable lesion with fluctuating fluid. The most common pyogenic bacteria that causes abscesses in animals include Arcanobacterium (Actinomyces) pyogenes, Streptococcus spp., Staphylococcus spp., and Fusobacterium (Sphaerophorus) necrophorum [11]. Both liver abscesses and fibrosis are common complications of migratory actions of parasite larvae, which elicit inflammatory responses, progressing to a fibrotic or granulomatous formation of tissues along the biliary tract.…”

“…Many studies [9,[11][12][13][14][15] in different African countries have looked at liver condemnation and shown a high prevalence of preventable parasitic and bacterial zoonosis, demonstrating the lack of a proper herd health programme necessary for the promotion of animal health in the various farms where these animals are bred. Meat safety should begin when the animal is conceived and continue to the point of delivery to the slaughterhouse.…”

A Quantitative Assessment of Causes of Bovine Liver Condemnation and Its Implication for Food Security in the Eastern Cape Province South Africa

Food production needs to double, with minimum waste, if hunger and poverty is to be alleviated in South Africa. The condemnation of liver during meat inspection represents a huge waste of a protein food resource. This paper measures the quantity of liver condemned in three abattoirs in the Eastern Cape Province of South Africa and assesses the causes and the monetary loss associated with these condemnations. A retrospective study (RS) (n = 51 302) involving the use of abattoir slaughter records from 2010-2012 and a post-mortem meat inspection (PMMI) (n = 1374) was conducted from July to December 2013. The RS revealed the leading cause of liver wastage as fasciolosis (5.95%, 4.48%, and 2.7%), fibrosis (2.74%, 2.37%, and 1.0%), and abscessation (1.11%, 2.78%, and 1.5%) for the 2010, 2011, and 2012 respectively. During the PMMI, the same factors caused liver condemnation in addition to calcification (8.3%, 6.8%, and 3.2%), Cysticercosis bovis (1.7%, 2.4%, and 1.3%) and improper evisceration (4.8%, 12.4%, and 27.1%) for the abattoirs X, Y, and Z respectively. A total of R 343, 330 (USD 45,271.07) was lost due to the condemnation of liver between 2010 and 2012. The further loss of 3290.4 kg of liver was calculated for the six month in 2013, and its financial value was R 59, 227.2 (USD 5889.82). The result of this study provide baseline information on major causes of liver wastage in cattle slaughtered in South Africa as well as the direct financial losses and demonstrate the huge waste of ideal protein food source.

Article HistoryTanzania has one of the largest populations of domestic ruminants in Africa. Their performance is less than their potential. Health, particularly disease due to gastrointestinal parasites, is a major constraint to improved productivity. Internal parasites also affect the country's very diverse and huge array of wild ruminants. This review is based on a thorough search of the formal and informal literature pertaining to gastrointestinal parasites of ruminants in Tanzania. The occurrence and geographical distribution of helminth (nematodes, trematodes and cestodes) and protozoan parasites are presented. Cattle, goat and sheep nematodirus (roundworm) infection usually comprises mixed infections of several taxa of which 13 species in nine genera have been recorded. A total of seven species of trematodes (flukes) in six genera have been found. Some six species of cestodes (flatworms) have been recorded, three being in the genus Taenia. The most prevalent species of protozoan parasites, of which seven have been identified in cattle and 18 in sheep and goats, belong to the genus Eimeria: four other species of protozoan parasites are also recorded. A general overview of the epidemiology of gastrointestinal parasites is provided and the main methods of control are discussed.Contribution/Originality: Domestic ruminants are an important part of the Tanzania economy. They contribute to food security, biodiversity, household income and human welfare. This paper reviews with the aid of 74 published references the status and distribution of the main internal parasites of domestic ruminants in Tanzania.

“…Most of these are supplied to the slaughter facilities by the rural based traditional livestock sector which constitutes more than 98% of the total livestock population in the country [1]. Apart from poor animal genetic makeup and poor management, the traditional livestock sector suffers high disease burden due to lack/inadequacy of veterinary services attributable to shortage of veterinary staff, poor infrastructure especially transport facilities and lack of diagnostic facilities and drugs [2][3][4][5][6]. As a result animals brought for slaughter into urban areas from the rural traditional sector may harbor chronic or subclinical infections some of which have zoonotic implication.…”
