在20世纪80年代中期,由于食用动物(肉用仔鸡、猪肉)引发的人沙门氏菌病迅速增加,引起了丹麦政府的高度重视,同时也为了保证丹麦出口动物产品的质量,丹麦政府于20世纪80年代后期在养殖业中制定实施了丹麦国家沙门氏菌控制计划。对肉用仔鸡、蛋鸡、蛋品和猪沙门氏菌进行控制。通过综合控制养殖场、屠宰场和食品加工厂,实施畜禽监控、清除感染动物和根据风险将动物和动物产品进行分类管理等具体措施,养殖业中沙门氏菌感染明显减少,人的动物源性沙门氏菌病也显著下降,控制措施达到了预期的效果。成为世界上为数不多的成功控制沙门氏菌的国家之一。 相似文献

上世纪80年代中期,由于丹麦肉用仔鸡沙门氏菌的传播,导致人沙门氏菌病的发病率迅速增加,丹麦政府对此极为重视,于1988年开始实施沙门氏菌控制计划,后来,由于猪和蛋鸡的沙门氏菌也导致人沙门氏菌病发病率的增加,因此猪和蛋鸡也被列入控制计划之中。通过综合控制养殖场、屠宰场和 相似文献

为了减少养殖业沙门氏菌病,降低因食用动物传染而引起的人沙门氏菌病,保证出口动物产品的质量,丹麦政府在养殖业中实施了沙门氏菌控制计划,对肉用仔鸡,蛋鸡,蛋品和猪沙门氏菌进行控制,通过综合控制养殖场,屠宰场和食品加工厂,实施畜禽监控、清除感染动物和根据风险将动物和动物产品进行分类管理等具体措施,养殖业中沙门氏菌感染明显减少,人的动物源性沙门氏菌病也明显下降,控制措施达到了预期的效果,成为世界上为数不多的成功控制沙门氏菌的国家之一,在2001年,丹麦社会因实施沙门氏菌控制计划而节省了2550万美元。 相似文献

丹麦出口商丹麦猪生产和屠宰场协会(TheFederationofDanishPigProducerAndSlaughterhouse俗称DS公司)的销售和出口部(SalesandExportAssociationForBreedingPigs简称SEA部)向我国出口的种猪是丹麦的SPF猪。为了弄清丹麦SPF猪群的运作,我们利用在丹麦执行产地检疫的机会,深入到DS公司SPF部、销售和出口部(SEA)以及哥本哈根兽医实验室等机构进行调查,对丹麦SPF计划有了一个大致的了解。丹麦猪SPF计划始建于70年代。是在丹麦DS公司的协调组织下,由农场主、地方兽医、SPF部兽医和丹麦王国农业部兽医局实验室共同完… 相似文献

[目的] 初步调查分析山东部分地区生猪屠宰环节沙门氏菌污染状况和血清型分布,了解生猪屠宰环节沙门氏菌的动态变化。[方法] 采集鲁东部、东北部、中部、西部和西南部地区不同规模屠宰场生猪屠宰环节样品共1012份,分离疑似沙门氏菌并利用PCR方法和血清凝集反应进行鉴定,单因子血清进一步进行血清型分析。[结果] 共分离鉴定沙门氏菌202株;鲁东、东北、中部、西部和西南部地区的沙门氏菌污染率分别为27.2%、12.6%、34.6%、12%和13.5%;沙门氏菌分离株共有9种血清型,以德尔卑(S.derby)、鼠伤寒(S.typhimurium)、汤卜逊(S.thompson)为主。[结论] 山东地区部分屠宰场生猪屠宰环节存在较严重的沙门氏菌污染现象,应加强屠宰环节致病菌监测,并在屠宰全程严格执行良好生产规范。 相似文献

养猪场以前饲养数量较少时采用传统的综合防控措施,如免疫接种、药物预防和治疗等,在疾病防控方面都起到关键作用且效果明显,但是随着饲养数量增加,只采用上述措施远远不够,应树立创新理念和生物安全措施,才能更有效的防控疾病发生。 相似文献

The aim of this study was to determine whether a hydrolysable tannin extract of sweet chestnut wood (Globatan®) has an inhibitory effect on Salmonella Typhimurium survival both in vitro and in vivo in pigs. In a first experiment, the minimal inhibitory concentration of Globatan® on 57 Salmonella Typhimurium isolates was determined. For all isolates, an MIC of 160–320 μg/ml was found. The second in vitro study revealed that Salmonella growth was strongly reduced using Globatan® concentrations of 25–50 μg/ml and nearly completely inhibited at a concentration of 100 μg/ml Globatan®. In an in vivo trial, two groups of six piglets, each group receiving feed with or without the addition of Globatan® (3 g/kg), were orally inoculated with 107 colony forming units of a Salmonella Typhimurium strain. Globatan® had no effect on faecal excretion of Salmonella, and no differences in colonization of the intestines and internal organs were demonstrated in pigs euthanized at 4 days post‐inoculation. In conclusion, the hydrolysable tannin extract used in this study showed strong action against Salmonella Typhimurium in vitro but not in vivo. 相似文献

Two trials were carried out to determine the effect of feed acidification upon Salmonella carriage in market-age pigs. In the first trial, the administration for the last 14 weeks of the fattening period of a commercial pelleted feed added with 0.6% lactic acid plus 0.6% formic acid (Lac-Formic-1.2) was compared to an unacidified standard diet (STD). A second experiment was carried out in two herds of growing pigs (Herd I, 3000 pigs; Herd II, 900 pigs) in which three different diets were assayed during the last 8-9 weeks of the fattening period: a diet containing 0.8% formic acid (Formic-0.8), a diet containing 0.4% lactic acid plus 0.4% formic acid (Lac-Formic-0.8) and a STD. In the first experiment, serological evolution of the infection was examined by ELISA and microbiological cultures (rectal samples and mesenteric lymph nodes) were also done. Feed intake by pen and the individual weight of the animals were also measured. In the second trial, blood, rectal samples and mesenteric lymph nodes were collected at slaughter in both herds (30 pigs per experimental group). In the first experiment, the acidified diet (Lac-Formic-1.2) reduced Salmonella carriers in mesenteric lymph nodes (Fisher's exact P < 0.01). In the second trial, Lac-Formic-0.8 diet significantly reduced Salmonella seroprevalence compared to the STD (P = 0.001) in both herds. Also Lac-Formic-0.8 and Formic-0.8 diets in Herd II showed a lower faecal excretion and Salmonella carriage in mesenteric lymph nodes than the STD (P < 0.05). Our results suggest that the administration of a combination of lactic and formic acids at the levels used in this study could be used to reduce Salmonella prevalence in finishing pigs. 相似文献
