1. Pathological Lesions Survey and Economic Loss for Male Cattle Slaughtered at Ismailia Abattoir
Abstract:
The study was a retrospective abattoir survey, undertaken for a period of one full year at the main traditional abattoir of Ismailia city, Egypt. During the survey, 9880 male cattle were slaughtered and inspected. As a result of postmortem inspections, 8 (0.10%) carcasses were totally condemned and 1456 (14.7%) organs had pathological lesions. Of the 1456 edible organs had pathological lesions; the sum of 1216 Kg was either totally or partially condemned. Based on weight of annual condemned organs, the estimated annual loss was 36480 Egyptian Pound. The gross pathological lesions detected in edible organs were in 117 of heart (8%), in 310 kidneys (21.3%), in 649 lunges (44.6%), in 260 livers (17.9%), and in 120 spleens (8.2%). The present study provides baseline data for the future monitoring of clean meat production in Ismailia abattoir. The condemnation of edible organs represents a significant economic loss to traders and livestock industry.
2. Prevalence, Intensity and Viability of Tissue Parasites Infected Bovine Carcasses at Ismailia -Egypt with Special Reference to their Zoonotic implications
Abstract:
The slaughterhouse represents a key control point of livestock production chain. It could be used to give a full picture about the zoonotic parasitic diseases. Therefore, this article aimed to determine the prevalence, intensity and viability of tissue parasites of bovines slaughtered at the main abattoir of Ismailia city, Egypt. From March 21st 2009 to March 20th, 2010, a total of 10055 cattle, 3811 buffalo carcasses were inspected, followed by parasitological and histopathological examinations. Stool specimens of 1200 farmers were examined for parasite eggs. Results revealed that the total prevalence of Cysticercus bovis was 0.47%, which was higher in cattle (0.57 %) than in buffalo (0.18%). 320 cysticerci were detected in 76 bovine carcasses, of which 103 (32.18%) were alive. The anatomical distribution of cysticerci was 55 (72.37%) heart, 13 (17.10 %) tongue, 7 (9.21 %) masseter, and 1 (1.31%) diaphragm. Hydatid cysts were detected in 106 (0.76%) carcasses. It was higher in buffalo 57 (1.49%) than cattle 49 (0.49%). A total 405 hydatid cysts were detected in 120 carcasses, of which 133 (32.83%) were viable. The predilection sites distribution of hydatid cysts were in the lung 84
(70%), 35 (29.17%) liver, 1 (0.83%) spleen. Sarcocystis macrocyst was detected grossly in buffalo carcasses only in 775 (20.33%). Macrocysts were identified to Sarcocystis fusiformis, and anatomically distributed as 403 (49.09%) in
esophagus, 333 (40.56%) in tongue, 85 (10.35%) in skeletal muscles. The total prevalence of liver flukes was 1.94%, which was higher in buffalo (3.23%) than in cattle (1.46%). Fasciola hepatica and Fasciola gigantica were identified. Generally, females showed significantly higher infection rates because of elder ages. In human, taniid eggs were detected in 2 (0.16%), Fasciola eggs 4 (0.41%) in stool specimens. In conclusion, the occurrence of such affections throughout the edible organs reflects their economical and public health impacts in Ismailia province that might be prevalent in Egypt in
large. These epidemiologic data could be a base of planning prevention and control programs.
