    There are limited studies on red offal condemnations and financial implications at high throughput abattoirs in Namibia. Causes of condemnation, temporal distributions and financial losses associated with red offal condemnations at a beef abattoir in Namibia from 2016 to 2018 were investigated. A total of 39157 red offal valued at N$6 422 586.00 (US$364 805) were condemned following the slaughter of 251697 cattle. Condemnations were dependent on year [X2(14) = 587.13, p<0.001], month [X2(77) = 1898.72, p<0.001] and season [X2(7) = 111.12, p<0.001] of study. Overall, 2016 had the most and 2018 the least condemnation of red offal (38.73% and 23.22%, respectively; p<0.05). Most red offal condemnations (13.34%, p<0.001) were recorded in June, with livers and lungs as the most condemned organs (54.32% and 29.88%, respectively; p<0.001). The highest condemnations were caused by miscellaneous causes (abscesses and hematomas) followed, in descending order, by inflammatory, parasitic and bacterial causes and contaminations (38.3%, 29.4%, 16.6% and 15.8%, respectively, p<0.05). Liver condemnations varied with the year and season of study [X2(20) = 1834.02, p<0.001 and X2(9) = 1010.43, p<0.001; respectively], as were lung condemnations according to pathological condition [X2(12) = 492.43, p<0.001 and X2(6) = 45.84, p<0.001; respectively]. The occurrence of hydatidosis in the summer and pneumonia in winter was greater than expected (15.1% and 4.3%; respectively, p<0.05). A substantial loss of revenue to the abattoir due to the condemnation of livers and lungs was determined. Meat inspection served as a control point for hydatidosis.

    Causes, patterns, and economic implications of carcass condemnation of cattle slaughtered at Oshana region, North of Namibia based on post-mortem inspection
    (Journal of Food Quality and Hazards Control, 2020-12-01) Mbiri, Pricilla; Mushonga, Borden; Madzinga, Charles; Madzingira, Oscar; Samkange, Alaster; Hikufe, Emmanuel H.; Kandiwa, Erick; Kamwi, Jessey Alice
    Background: Meat inspection is one of the essential tools for ensuring good quality and safe meat. The objective of this study was to evaluate carcass condemnation of cattle slaughtered in Oshana region, North of Namibia. Methods: In this 4-year retrospective study, causes, patterns, and economic implications of carcass condemnation of cattle slaughtered in Oshana region, North of Namibia were evaluated based on post-mortem inspection procedure. The SPSS software version 25 was used for statistical analysis. Results: Overall, 0.37% (120 out of 32 648) beef carcasses were condemned during the period of this study. The major causes of condemnation of carcasses were bruising (60 out of 120; 50%), followed by pus contamination. The condemnation rate in female cattle (65%) was significantly (p<0.05) higher than male cattle (35%). Overall, a significantly greater number (p<0.05) of carcasses were condemned in summer (74.2%) than in winter (25.8%). Conclusion: This study identified bruising, pus contamination, and cachexia as the major causes of bovine carcass condemnation in North of Namibia and showed that carcass condemnation rate varied with the year, season, and age.
