The prevalence of Taenia saginata cysticercosis in cattle slaughtered for meat in Addis Ababa Abattoir, Ethiopia between September 2004 and August 2005 was
reported. The examination of various organs of 11227 cattle in Addis Ababa Abattoir showed that 842 (7.5%) were infected with
T. saginata cysticercosis. The tongue, masseter muscles, cardiac muscles, triceps muscles and thigh muscles were the main predilection
sites of the cysts. The cysts of bovine cysticercosis were also identified on the spleen, intercostal muscles, diaphragm and
liver. Out of 10329 male cattle, examined, 783 (7.6%) had cysts of bovine cysticercosis while 59 (6.6%) of the 898 female
animals investigated were infected. The animals slaughtered were all adults. No significant difference in prevalence rates
was recorded between the sexes. The prevalence of bovine cysticercosis was higher in local zebu cattle breeds than Holstein-Frisian
cattle. 相似文献

The prevalence of parasitic infections responsible for the condemnation of carcasses and viscera during meat inspection, and their economic implication, was estimated in a year long abattoir survey of 10 277 slaughtered farm animals in the region of Trikala, Greece. The organs examined for the presence of parasitic lesions during meat inspection were: liver and lungs of all animals, rumen of cattle, small intestine of lambs and kids, and muscles of cattle and swine. The parasitic lesions observed in the lungs of cattle, sheep and goats were caused only by hydatid cysts. No hydatid cysts were observed in the lungs of swine. The parasitic lesions observed in the liver of cattle, sheep and goats were as a result of hydatid cysts and flukes of Fasciola hepatica and Dicrocoelium dendriticum, while those of swine were due to milk spots only. Moniezia sp. proglottids were found in the small intestine of lambs only. The prevalence of parasites responsible for the condemnation of marketable organs was low (0.26%). Parasites were responsible for 22% of the total of condemned organs, and their annual cost was 99, 00 GDR (approximately 292 Euros). The parasites most contributing to marketable organ condemnation were hydatid cysts (26%) and D. dendriticum flukes (26%). 相似文献

The study was carried out from July 2007 to June 2008 in Wolaita Sodo Abattoir to assess the status of hydatidosis in cattle.
Routine meat inspection, hydatid cyst count and characterization were conducted. Out of 400 cattle slaughtered in Wolaita
Sodo Abattoir 64 (16%) animals were found harboring hydatid cysts. Thorough meat inspection in the abattoir revealed that
74 visceral organ were found harboring one or more hydatid cysts. The infection of the lung, liver, spleen and kidney were
found to be 45.94% 45.94%, 6.75% and 1.35% respectively. From the total of 283 hydatid cysts counted 153(54.06%), 17(6.00%),
5(1.76%), 108(38.16%) were found to be small, medium, large and calcified cysts respectively and 170(60.28%), 5(1.76%) and
108(38.16%) were sterile, fertile and calcified cysts respectively. The rate of cyst calcification was higher in the liver
than in the lung while fertility rate was higher among the cysts of the lung. Hydatid cyst viability rate of 40% was observed. 相似文献

The study was conducted from May 2005 to December 2006 in Bahir Dar Abattoir to assess the current status of hydatidosis in
cattle and sheep. Hydatid cyst count and characterization were conducted based on routine meat inspection. Of the total 420
cattle and 340 sheep slaughtered in Bahir Dar Abattoir 143 (34.05%) and 36 (10.6%) animals were found harboring hydatid cysts
respectively. Thorough meat inspection in the abattoir revealed that 202 and 54 visceral organs were found harboring one or
more hydatid cysts in cattle and sheep respectively. Differences in prevalence rates between the two species of animals were
highly significant (P < 0.001). The infection of the lung, liver, kidney, spleen and heart were found to be 57.9% , 36.6%
, 3% , 1.5% , 1% in cattle and 50%, 48.1% and 1.9% in sheep respectively. From the total of 864 in cattle and 138 in sheep
hydatid cysts counted 315 (36.4%), 268 (31.0%), 65 (7.5%), 216 (25.0%) in cattle and 92 (66.7%), 20 (14.5%), 1 (0.7%), 25
(18.1%) in sheep were found to be small, medium, large and calcified cysts respectively and 484 (56.0%), 164 (18.9%), 216
(25%) in cattle and 35 (25.4%), 78 (56.5%), 25 (18.1%) in sheep were sterile, fertile and calcified cysts respectively. Viability
rates of 62.2% in cattle and 78.2% in sheep were observed. The rate of cyst calcification was higher in the liver than in
the lung while fertility rate was higher among the cysts of the lung for both cattle and sheep. 相似文献

Sixty-seven young cattle grazed on a sewage farm since birth were slaughtered and the carcases finely dissected in search of Cysticercus bovis. Forty-seven (70%) were infected, but only 49% of infected cattle had cysts in tissues considered to be sites of predilection and only 19.8% of all cysts found were located in these sites. Most of the remaining cysts were distributed randomly throughout the masculature. 相似文献

Cysticercus bovis was detected at meat inspection in 2.16 per cent of 102,087 carcases of cattle from Matabeleland Province, slaughtered in Bulawayo during a period of 11 months. Lightly infested (detained) carcases accounted for 95 per cent of those with cysticercosis. The head was the only site affected in 58.4 per cent of the detained carcases, the shoulder in 20.1 per cent and the heart in 7.9 per cent. In more heavily infested (condemned) carcases 81.1 per cent had at least three sites affected. The incidence of cysts was highest in older male animals but in younger animals it was highest in cows. In the detained carcases an average of 1.5 cysts were found, of which 76 per cent were live and 24 per cent dead. Condemned carcases had more than 58 cysts on average, of which 98 per cent were live and 2 per cent dead. Live cysts were more common in older cattle and dead cysts were more common in younger animals. The incidence of C bovis in carcases of cattle originating from communal areas was 3.2 per cent compared with 1.6 per cent in those originating from commercial farms. 相似文献

A survey was carried out at Kano abattoir in order to estimate the incidence of hydatidosis and cysticercosis in slaughtered livestock. Of the animal species examined, hydatid disease was found in sheep (11.4 per cent), goats (26.5 per cent), cattle (14.7 per cent) and camels (55.5 per cent). Cysticercus tenuicollis was found to be most prevalent in goats (34.2 per cent), followed by sheep (21.4 per cent) and cattle (0.1 per cent). Out of 4844 cattle examined, less than 2 per cent haboured Cysticercus bovis cysts; while Cysticercus ovis cysts were found in sheep (1 per cent) and goats (0.8 per cent). 相似文献

The aim of this study was to determine the fertility and viability of hydatid cysts in slaughtered sheep and cattle. Cysts
were collected from the liver and lungs of 169 sheep and 171 cattle infected with Echinococcus granulosus when slaughtered
in industrial abattoir in Sari, Iran, 2007–2008. Fertility was determined by the examination of cyst fluid for the presence
of protoscoleces. The viability of the protoscoleces was assessed by staining with 0.1% aqueous eosin solution. The fertility
rates of hepatic cyst of sheep and cattle were 47.1% and 1.4%, respectively and the fertility rates of pulmonary cyst of sheep
and cattle were 39.4% and 8.1%. In the sheep, the fertility of cysts in the liver was higher than that in lungs, but in the
cattle the fertility of cysts in lungs was higher than liver. The viability of protoscoleces of fertile cysts for sheep and
cattle were about 76.9% and 82.5%, respectively. Based on the finding in the present study, effort should be made to control
transmission of cystic echinococcosis by safe disposal of Echinococcus cysts such that dogs cannot have access to the cysts. 相似文献

Bovine tuberculosis (BTB) is a widespread and endemic disease of cattle in Ethiopia posing a significant threat to public health. Regular surveillance by skin test, bacteriology, and molecular methods is not feasible due to lack of resources. Thus, routine abattoir (RA) inspection will continue to play a key role for national surveillance. A cross-sectional study was conducted at Woldiya municipal abattoir from April 1, 2009 to April 5, 2010 to estimate the prevalence of BTB in slaughtered cattle on the basis of detailed abattoir inspection and to compare efficacy of RA inspection with respect to detailed abattoir inspection and isolation and identification of Mycobacterium. Diagnostic accuracies (with corresponding measures of statistical uncertainty) were determined by computing test property statistics (sensitivity and specificity). Agreement between RA and detailed abattoir inspections was measured using kappa statistics. Out of 1,029 slaughtered heads of cattle examined during the study period, 63 (6.12 %) and 15 (1.45 %) were diagnosed with gross tuberculous lesions by detailed abattoir meat inspections and RA meat inspections, respectively, making a prevalence of 6.12 % (95 % CI: 5.2–7.1) on the basis of detailed abattoir inspection. About 59.45 % of tuberculous lesions were observed in the lungs and associated lymph nodes, whereas 35.13 % lesions were from the lymph nodes of the head. From 63 cattle suspected with tuberculosis (TB) based on detailed abattoir meat inspection, nine (19.05 %) were identified as Mycobacterium bovis, while three (4.8 %) as Mycobacterium tuberculosis. The sensitivity of RA meat inspection was 23.8 % in comparison to the detailed abattoir meat inspection and 25 % in comparison to culture, respectively. Poor agreement (k?=?0.37) was seen between RA meat examination and detailed abattoir meat examination methods. Similarly, poor agreement (k?=?0.013) was seen between RA meat examination and culture results. In conclusion, relatively higher prevalence (6.12 %) was recorded in Woldiya municipal abattoir on the basis of detailed Abattoir inspection and RA meat inspection protocols currently utilized in Ethiopia which are insufficient to detect the majority (76.19 %) of TB lesions at the gross level, which indicates the magnitude of meat borne zoonotic TB as an ongoing risk to public health. Detailed abattoir inspection protocols were demonstrated to improve the detection level by approximately fourfold. In conclusion, routine meat inspections have limitations in detecting BTB-suggestive lesions which indicate the magnitude of meat-borne zoonotic TB as an ongoing risk to public health. 相似文献

Objective The first national abattoir survey of Cysticercus bovis (‘beef measles’) in cattle was conducted in February 2008. Methods During the data collection period, 493,316 cattle were subjected to standard postmortem procedures, including incision of the masseter and heart muscles. On-site veterinarians were asked to record the location of any C. bovis cysts, as well as the National Livestock Identification System ear tag numbers of infected animals. Veterinarians were asked to submit samples for laboratory confirmation by histology and polymerase chain reaction testing. Results Of the 23 samples submitted, none was positive for C. bovis by either diagnostic method. Conclusions Occasional, isolated diagnoses of beef measles are still made in most states of Australia, but since the last regional surveys were conducted 30 years ago, when the estimated prevalence was 50 to 200 per 100,000 cattle slaughtered, the parasite has become extremely rare. 相似文献

Residual antimicrobials in food constitute a risk to human health, but poor knowledge is available about the significance of contaminated meat in developing countries. The purpose of the study was to determine the occurrence of antimicrobial drug residues in pork products in Madagascar. The occurrence of antimicrobial drug residues in pork meat were investigated by the Premi® test (DSM©) technique. There was a high incidence rate of drug residues, with 360 (37.2 %) meat samples being contaminated. A significant increase was observed between 2010 and 2011, with 32 and 39%, respectively. Pork meat samples are less contaminated by drug residues when animals are slaughtered in urban abattoirs (34.4%) vs in provincial abattoirs (42.2%), suggesting that animals under treatment (or sick) are sold preferentially in local abattoir. Drug residue levels in pork meats purchased in Madagascar appear to be serious public health problem at the moment. 相似文献

A survey carried out to determine the prevalence of visible Surcocystis spp. infection in 100 slaughtered cattle in a South Island abattoir revealed 64% infected. Although all ages, genders, breeds and export grades were infected, only host age had a statistically significant effect on the infection rate. Infections were most common in the rectus abdominis and the psoas muscles (47% and 41% respectively). Most infections were light, with less than ten macrocysts seen, though infections of more than 50 macrocysts occurred. The average macrocyst length was 4.WO.10 mm (SE) (n = 233), the average cyst wall thickness 5.3 +/- 0.2 microm (SE) (n = 45). It is thought that the actual prevalence of infection is higher than that recorded and reasons for this are discussed. 相似文献

A cross-sectional study to determine the prevalence of bovine cysticercosis and hydatidosis was conducted from October 2007 to March 2008 in cattle slaughtered at the Jimma municipal abattoir. Cyst distribution and viability of bovine cysticercosis and hydatidosis were also determined. A total of 512 carcasses were inspected of which 15 (2.93%) and 161 (31.44%) were infected with Taenia saginata metacestodes and hydatid cysts, respectively. From a total of 109 cysticerci collected from infected carcasses, 47 (43.12%) were viable. The anatomical distribution of the cysticerci was, shoulder muscle (39.5%), heart (33.9%), neck muscle (13.8%), tongue (10.1%), masseter muscles (1.8%) and diaphragm (0.9%). Of the 1171 hydatid cysts collected 223 (19.0%) were fertile, 505 (43.1%) sterile, 49 (29.8%) calcified and 94 (8.0%) contained pus. A greater proportion of fertile cysts were found in the lungs than in other organs. It was concluded that these zoonotic cestodes deserve due attention to safeguard public health, and that further studies are needed on genotyping, epidemiology and public health importance of Echinococcus granulosus in the study area. 相似文献

Toxoplasmosis is one of the most important zoonotic diseases worldwide and is caused by the protozoan Toxoplasma gondii. Besides vertical infection during pregnancy, humans can get infected post-natally either by peroral uptake of sporulated Toxoplasma oocysts or by ingestion of tissue cysts upon consumption of raw or undercooked meat. The aim of this study was to approximate the risk of human infection via meat consumption by estimating the seroprevalence of T. gondii in slaughtered animals in Switzerland and to compare data with prevalences assessed 10 years ago. The study included pigs, cattle, sheep and wild boar of different age groups and housing conditions whenever possible and applicable. A P-30-ELISA was used to detect T. gondii-specific antibodies and to determine seroprevalences in meat juice of slaughtered animals. A total of 270 domestic pigs (120 adults, 50 finishing, 100 free-ranging animals), 150 wild boars, 250 sheep (150 adults, 100 lambs) and 406 cattle (47 calves, 129 heifers, 100 bulls, 130 adult cows) were tested. Seropositivity increased with the age of the assessed animals. Independent of the age-group, the overall seroprevalence was lowest in wild boars (6.7%), followed by pigs (23.3%), cattle (45.6%) and sheep (61.6%), respectively. Conventional fattening pigs and free-ranging pigs surprisingly had comparable seroprevalences (14.0% and 13.0%, respectively). Unlike in other European countries, where generally a decrease in the number of seropositive animals had been observed, we found that the prevalence of seropositive animals, when compared with that of 10 years ago, had increased for most species/age groups. Conclusively, the results demonstrated a high seroprevalence of T. gondii in animals slaughtered for meat production and revealed that increasing age of the animals is a more important risk factor than housing conditions in Switzerland. 相似文献

A 6-year retrospective study (2000–2005) of animals slaughtered at the Zango abattoir in Zaria, Kaduna State, Nigeria was
carried out to determine disease conditions encountered in slaughtered animals. Records kept at the abattoir were analysed.
A total of 69,307 cattle, 3,820 goats and 1,763 sheep were slaughtered for the period under study. Of the 69,307 cattle slaughtered
for the period, 22,459 (32.41%) were males and 46,848 (67.59%) were females, while 1,763 sheep were slaughtered comprising
of 506 (28.70%) males and 1,257 (71.30%) females, and 3,820 goats made up of 1,212 (31.73%) males and 2,608 (68.27%) were
females. The major disease and/or pathological conditions were helminthosis (fascioliasis, haemonchosis and paramphistomosis)
16.20%, Streptothricosis 4.15%, Pericarditis 2.20%, liver cirrhosis 2.08%, abscesses 1.04%, pneumonia 0.14%, nephritis 0.05%
and Contagious Bovine Pleuropneumonia, Tuberculosis and Nocardiosis 0.01% each. Out of the 15,075 infected organs, 13,314
(88.38%) were partially salvaged while 1,751 (11.6%) whole organs were condemned. A total of 1,239 pregnant cows, 221 pregnant
ewes and 637 pregnant does were slaughtered, representing a foetal wastage of 2.65% for cattle, 17.58% for sheep and 24.43%
for goats. The result of this study apart from serving as an indicator of field disease condition also demonstrates cases
of serious losses in production due to slaughter of pregnant animals especially for sheep and goats. 相似文献

The genetic diversity of 283 Mycobacterium bovis (M. bovis) and 10 Mycobacterium caprae (M. caprae) strains, isolated between 2002 and 2007 from cattle, goat, red deer and wild boar from six different geographical regions of Portugal was investigated by spoligotyping. The technique showed a good discriminatory power (Hunter-Gaston Index, h=0.9) for the strains, revealing 29 different patterns. One pattern (SB0121) was clearly predominant, accounting for 26.3% of the isolates; ten patterns, representing 20.7% of the isolates, had never been reported previously. Multiple spoligotypes were detected in thirteen cattle and one goat herd, most of which were found in beef cattle and extensive management regions, suggesting different infection sources. With the exception of two spoligotypes, those in wildlife species were also found in domestic species. 相似文献

The distribution of Taenia saginata cysts was recorded in 23 experimentally infected calves. The calves harboured between two and 2569 cysts. A median of 15.7 per cent of the cysts were located in the heart and 6.5 per cent in the masseter muscles, the organs usually considered as the most important predilection sites. From these findings a simple probability model was used to estimate the meat inspection sensitivity at different infection levels. It was concluded that the possibility of detecting infected cattle is limited especially when, as in Denmark, the majority of animals are lightly infected. 相似文献

Prevalence and seasonal incidence of larval and adult cestode infections of sheep and goats in eastern Ethiopia 总被引：1，自引：1，他引：0
A study on the prevalence and seasonal incidence of cestode parasite infections of sheep and goats was carried out in eastern Ethiopia for 2 years (May 2003-April 2005). During this period, viscera including liver, lungs, heart, kidneys and the gastro-intestinal tract were collected from 655 sheep and 632 goats slaughtered at four abattoirs located in the towns of Haramaya, Harar, Dire Dawa and Jijiga. At the abattoirs the abdominal, thoracic and pelvic cavities as well as the muscle surfaces of all animals were visually examined for the presence of larval (cystic) stages of cestode parasites. The viscera were transported within 24 h to the parasitology laboratory of Haramaya University and were examined for larval and adult cestodes following standard procedures. The most prevalent metacestodes (larval cestodes) were Cysticercus ovis (Taenia ovis), Cysticercus tenuicollis (T. hydatigena) and hydatid cysts (Echinococcus granulosus). In sheep, the overall prevalence was 26% for C. ovis, 79% for C. tenuicollis, and 68% for hydatid cysts. Similarly, for goats, the corresponding prevalence was 22%, 53% and 65%, respectively. The difference between sheep and goats in prevalence of C. tenuicollis was significant. The high prevalence of hydatid cysts in both sheep and goats indicates that cystic echinococcosis/hydatidosis is a public health problem in these regions which requires implementation of control measures, including public health education, strict meat inspection and control of stray dogs. The results of the survey also implies that infections of small ruminants with these metacestodes are responsible for condemnation of substantial quantities of affected organs and muscles and therefore of direct economic importance. Intestinal infections with adult tapeworms of Moniezia expansa, Avitellina centripunctata and Stilesia globipunctata, and bile duct infections with Stilesia hepatica were also common in both sheep and goats. In sheep, the overall prevalence of these tapeworms were 61%, 20%, 24% and 39%, respectively. Similarly, the overall prevalence of these parasites in goats was 53%, 21%, 27% and 36%, respectively. 相似文献

Holstein cattle of a small scale dairy production systems were screened for Brucella abortus antibodies in 21 villages in Cameroon by ELISA. Results show a general seroprevalence of 8.4% in Holstein cattle. Of the
192 cows tested, 14 were infected giving a within-sex seroprevalence of 7.3% while 6/74 bulls were infected with a seroprevalence
of 8%. There was no evidence (P=0.11) of differences in seroprevalence between age groups although animals above one year
and below three years accounted for nearly half of the infected animals. 64% of infected animals were found in three locations
(P=0.015): Kutaba (32%), Bamendankwe (16%) and Finge (16%). A specific control programme should be organized at these locations.
Measures should be taken to ensure the eradication of the disease within the population and sound control measures adopted
to avoid a further spread of the disease to larger cattle populations. Infected animals should be slaughtered systematically.
All farmers should be advised to boil milk before consumption. Vaccination against Brucella abortus should be instituted and use of artificial insemination propagated. In order to ensure a productive and healthy population
of Holstein cows within the dairy production scheme, regular Brucella testing should be instituted. 相似文献
