“…The liver is basically condemned due to preventable lesions/diseases detected during routine post-mortem meat inspection. Other reasons for condemnation may be for the aesthetics value of the liver and faulty slaughter techniques [6][7][8][9][10]. For livestock productivity to be doubled and to help mitigate food insecurity, the reduction in food wastage, especially along the production line, is crucial.…”

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.

Epidemiology and economic impact of bovine cysticercosis and taeniosis caused by Taenia saginata in northeastern Spain (Catalonia)

BackgroundIn Catalonia (north-eastern Spain), Taenia saginata has been described in cattle but its occurrence in humans is unclear. Moreover, whether cattle acquired the infection in Catalonia or outside Catalonia and its economic impact have not been investigated. This study aimed to estimate the prevalence and spatial distribution of bovine cysticercosis in Catalonia (2008–2015), and the burden from T. saginata upon the animal and human sectors in Catalonia (2013–2015).MethodsData on cattle diagnosed with cysticercosis at meat inspection were collected and analysed. Cattle movement history was used to identify the most likely place of bovine cysticercosis infection and to investigate its spatial distribution. Data on taeniosis treatment (niclosamide and praziquantel) costs and their supply in Catalonia as well as data on patients attending primary care with diagnosis of taeniosis were collected. The financial impact associated with T. saginata due to carcasses condemned and frozen, meat inspection and human taeniosis was estimated.ResultsDuring 2008–2015, between 18 and 107 cattle were found positive for cysticercosis each year (prevalence at slaughter of 0.010%). Movement history was available for 44% of the infected cattle and in 53% of them Catalonia was identified as the place where the infection was acquired with highest probability. Two significant bovine cysticercosis clusters were detected. The number of patients diagnosed with taeniosis in primary care during the period 2013–2016 was 41–63/year. The overall economic impact of T. saginata (2013–2015) amounted to 154,903 €/year (95% CI: 113,075–196,762). Meat inspection accounted for 81.9% (95% CI: 75.8–86.2%) of the costs, followed by costs due to carcass condemnation and freezing (9.4%; 95% CI: 6.9–12.8%), and taeniosis-associated costs (8.7%; 95% CI: 6.7–11.6%). Costs due to freezing and condemnation of carcasses reached 19,442 €/year (95% CI: 17,528–21,391) (509 €/lightly infected carcass and 1,140 €/heavily infected carcass). Taeniosis-associated costs were estimated at 12,848.5 €/year (237 €/patient).ConclusionsThe public health risk of T. saginata in the area seems to be low. The economic impact due to T. saginata was mainly attributed to meat inspection. The cost due to carcass condemnation and freezing was limited compared to the revenue of the beef sector. Developing and implementing risk-based surveillance is needed to lower the costs of meat inspection. Considering cattle movements might be useful in the development of such a strategy.

“…However, the level of detection of bovine cysticercosis by routine meat inspection may be improved by training and motivation of meat inspector as well as ensuring the level of compliance with inspection protocols is adhered to and that the quality of inspection facilities is maintained (Laranjo‐González et al, ). Dupuy et al () demonstrated the importance of compliance with inspection protocols after reporting an increase in prevalence from 1% to 9% obtained by routine meat inspection in the Brittany region in France by simply cutting the heart into 2–3 mm thick slices, while complete cutting of the predilection sites of the parasite (detailed meat inspection) increased a zero prevalence rate of bovine cysticercosis to 23% in Belgium (Laranjo‐González et al, ).…”

Background The aim of this review was to establish the current epidemiology of taeniosis, cysticercosis and trichinellosis among humans and animals in Iran by carrying out a comprehensive assessment of published articles reporting on these foodborne zoonotic diseases across the country. Methods The Preferred Reporting Items for Systematic Reviews and Meta‐Analyses (PRISMA) guideline was used in the search for relevant published articles reporting on cysticercosis, taeniosis and trichinellosis in Iran using a number of appropriate key words. The search was conducted through PubMed, Web of Science, Google Scholar, SpringerLink, SCOPUS, WHOLIS, FAO and CDC. Published scientific articles including journals, books and book chapters reporting on cysticercosis, taeniosis and trichinellosis in Iran for the period between 1967 and 2018 were selected. Results A total of 37 articles met the search criteria and were incorporated in this review. Of these, 10 (27%) reported on human taeniosis, 15 (40.5%) on cysticercosis (10 on Taenia saginata and five on Taenia spp. cysticercosis) and 12 (32.5%) on trichinellosis. T. saginata was implicated in all human taeniosis cases. All Taenia spp. cysticercosis cases were reported among domesticated pigs and wild animals. A case of neurocysticercosis was reported in a male patient at Shohada Hospital in Tehran. Eleven (91.7%) of the 12 studies reported on trichinellosis among wild animals, while one (8.3%) study detected anti‐Trichinella IgG in 8 (2.2%) of the 364 at‐risk human beings tested. Nevertheless, most of these studies were carried out in northern Iran. Conclusion This review found T. saginata to be the most prevalent and of greater economic and public health significance in Iran. However, T. solium and Trichinella spp. were of little significance to human health. More studies should focus on other regions besides northern Iran.
