Condemnation of the liver represents a reduction in available food resources. Identifying and quantifying the causes of liver condemnation is the first step in diseases surveillance aimed at preventing further liver losses at the abattoir. Furthermore, it can be used to monitor disease that may lead to monetary losses associated with meat condemnation and syndromic surveillance system for improved detection of disease outbreaks. Meat inspection is a veritable tool in data gathering on notifiable diseases, zoonoses, and endemic production diseases. Although PMMI has been criticized for its limitations, there is evidence that substantiates the sensitivity of meat inspection for identifying specific diseases of humans and animal importance. The monitoring and surveillance of emerging infectious and zoonotic diseases in food animals should be an integral component of every food safety system. 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. 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). A total of R 343, 330 (USD 45,271.07) was lost due to the condemnation of liver between 20. 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 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.
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. The condemnation of liver during meat inspection represents a huge waste of a protein food resource. Food production needs to double, with minimum waste, if hunger and poverty is to be alleviated in South Africa.
