HACCP 全面品质管理体系的发展论述 总被引:2,自引:0,他引:2
一.HACCP体系的发展历程早在60年代,由开发美国宇航食品的Pillsbury公司,航空航天局(NASA)和美国陆军Natick技术开发研究所共同对HACCP系统进行了研究。1971年,食品保护委员会公布并成功地应用于生产低酸性食品罐头的安全与品质管理。到1987年,美国农业部食品安全检查局(FSIS)、FDA、海洋渔业局和美国陆军Natick研究所合作具体推行食品HACCP监视方式。1989年11月,《食品的危害分析和重点管理方式是食品加工的原则》的发表,使HACCP系统开始得到推广应用。美… 相似文献

迟缓爱德华氏菌的溶血特性 总被引:7,自引:0,他引:7
分析了不同来源的28株Et的溶血特性。分别以平板法(PlateAssay,PA)、接触法(ContactHemolysis,CH)及上清法(SupernatantAsay,SA)检测Et的溶血性,阳性率依次为75%、75%、5714%。PA和CH的符合率为100%。凡SA检测为阳性的,PA、CH检测皆为阳性。培养基中加入螯合剂EDDA造成环境缺铁,结果,约3214%Et的胞外溶血素显著增加。经胰酶、热处理后,ATCC15947株溶血活性丧失,提示Et溶血素是一种不耐热蛋白样物质。 相似文献

HACCP体系在食品加工企业中的应用 总被引:2,自引:0,他引:2
HACCP(危害分析与关键控制点)是以预防为基础的食品安全系统。HACCP体系在食品加工过程中的应用是由Pillsbury公司在国家航空和宇宙航行局(NASA)、美国陆军Natick实验室、美国太空实验室计划组的合作和参与下发起的。在60年代初,该系统在用于美国太空计划食品制造时100%防止了细菌性、病毒性病原体、毒素及化学或物理的能导致疾病或对飞行员伤害的污染。HACCP替代了终产品检验方法,以提供食品的安全保证和已被广泛应用的生产安全食品的预防系统。随后,HACCP系统已被普遍看作一有效的控… 相似文献

REASONS FOR PERFORMING STUDY: Centesis of the bicipital bursa using an 8.9 cm long spinal needle has been reported but the alternative of employing a 3.8 cm long hypodermic needle requires validation. OBJECTIVE: To compare the efficacy of 2 different methods of centesis of the bicipital bursa and to evaluate the usefulness of ultrasonographic imaging to determine the location of solution administered when centesis of the bursa is attempted. METHODS: For Trial 1, 6 clinicians, who had no previous experience of centesis of the bicipital bursa, attempted to inject a solution composed of an aqueous radiopaque contrast medium and physiological saline solution (PSS) into the bicipital bursae of 2/12 horses using the previously described distal approach to inject one bursa and a proximal approach to inject the contralateral bursa. The bicipital tendon and bursa were examined ultrasonographically before and after injection; and both shoulders were examined radiographically to identify the location of the medium. In Trial 2, another 6 clinicians, also with no previous experience of centesis, repeated Trial 1, using 6 horses, but the radiopaque contrast medium was mixed with air instead of PSS. RESULTS: Accuracy of centesis using the proximal approach was 39% and that of the distal approach 28%. Ultrasonographic examination of the shoulder allowed the location of solution and air to be accurately predicted in all 12 shoulders examined. CONCLUSIONS: Clinicians who have had no previous experience performing centesis of the bicipital bursa are unlikely to be successful in centesis using either approach. Radiographic examination after injecting a radiopaque contrast medium may be necessary to assess the success of centesis especially if bursal fluid is not obtained during centesis. Injecting air along with the radiopaque contrast medium provides more accurate ultrasonographic confirmation of centesis and better radiographic definition than does injection without air. 相似文献

以国际标准强毒R株人工感染非免疫产蛋鸡,定时扑杀,分别从鼻窦、眶下孔、气管、肺、气囊、卵巢和输卵管分离MG,并收集感染鸡所产蛋分离MG。结果表明,人工感染48小时后上、下呼吸道及肺已被全面感染,96小时气囊已被感染,120小时输卵管已能分离到MG,卵巢始终分离不到MG。人工感染鸡自144小时便能在其所产蛋中分离出MG。药物治疗能在72小时内消除感染,油乳剂苗则需24天后逐渐降低蛋内MG分离率,药物卵内注射、种蛋药浴、高温处理均能杀死卵内MG,但以研制的种蛋浸泡剂药浴效果为最好。 相似文献

Effects of size of ingestively masticated fragments of plant tissues on kinetics of digestion of NDF
Ingestively masticated fragments were collected and sized via sieving. Different sizes of esophageal masticate and ruminal digesta fragments, and ground fragments of larger masticated pieces were incubated in vitro, and undigested NDF remaining at intervals of up to 168 h of incubation was determined. The ruminal age-dependent time delay (tau) for onset of digestion of NDF was positively correlated (P < 0.004) with the mean sieve aperture estimated to retain 50% of the fragments between successive sieve apertures (MRA). Degradation rate of potentially degradable NDF (PDF) and level of indigestible NDF were not related (P > 0.10) to MRA of masticated and ground fragments. Estimates of tau were positively related to MRA, with slopes of bermudagrass < corn silage < ruminal fragments of corn silage. It was concluded that fragment size-, and consequently, ruminal age-dependent onset of PDF degradation of a mixture of different fragment sizes results in an age-dependent rate of degradation of the more rapidly degrading of two subentities of PDF. Models are proposed that assume a tau before onset of simultaneous degradation of PDF from two pools characterized as having gamma-modeled age-dependency and age-constant rates. The ruminal age-dependent pool seems to be associated with the faster-degrading pool, and its rate parameter increases with range in MRA in the population of fragments. Conceptually, the ruminal age-dependent rate parameter for PDF degradation seems to represent a composite of several effects: 1) effects of the size-dependent tau; 2) range in MRA of the population of ingestively masticated fragments; and 3) subentities of PDF that degrade via more rapid age-dependent rates compared with subentities of PDF that degrade via age-constant rates. The estimated fractional rates of ruminative comminution of ingestively masticated fragments (0.060 to 0.075/h) were of a magnitude similar to the mean fractional rates of PDF digestion (0.030 to 0.085/h), which implies that ruminative comminution may be first-limiting to fractional rate of PDF digestion. The in vivo roles of ingestive and ruminative mastication of fragments on PDF degradation must be considered in any kinetic system for estimating PDF digestion in the rumen. These results and others in the literature suggest that the rate of surface area exposure rather than intrinsic chemical attributes of PDF may be first-limiting to degradation rate of PDF in vivo. 相似文献
