生猪屠宰肉品品质检验存在问题及对策

正肉品品质检验是保障上市猪肉质量安全的重要手段和措施,与生猪屠宰检疫互为补充、相互印证。《生猪屠宰管理条例》《中华人民共和国农业农村部公告第10号》《生猪屠宰产品品质检验规程(GB/T1996-1999)》等要求屠宰企业做好肉品品质检验工作,检验合格方可销售。当前,生猪屠宰中肉品品质检验工作中还存在许多问题和不足,亟待改善。     

生猪屠宰产品品质检验主要内容

定点屠宰厂（场）要生产优质、安全的猪肉产品，除了搞好屠宰检疫外，还要把好产品质量检验关。为此，市县农牧部门在审查生猪定点屠宰厂条件时，应考核肉质检验人员技术水平。他们除熟悉国家标准“生猪屠宰产品品质检验规程”（GB／T１９９６－１９９９）和“肉品卫生检验试行规程”等相关法律、法规、规章、标准外，还应熟练掌握肉质检验内容。１一般性疾病猪胴体、脏器、头蹄的鉴定和处理染上一般性疾病的猪的胴体、内脏和头蹄有各种病理变化，根据其变化，区别疾病的性质，做出正确的卫生评价和处理，以保证肉品的安全利用。１．１红…     

如何才能让百姓吃上“放心肉”

实行生猪定点屠宰,是市政府为落实《中华人民共和国动物防疫法》和国务院《生猪屠宰管理条例》精神,保证市民真正吃上放心肉,促进生猪生产和流通而采取的一项重大举措。我市的定点屠宰经过了2年的风风雨雨,虽然未有成功的喜悦,但也积累了正反两方面的经验。今年4月定点屠宰工作重新运作,对此谈3点看法。1正确理解屠宰检疫与肉品品质检验的关系国务院《生猪屠宰管理条例》强调,未经屠宰检疫和肉品品质检验的肉品不能出厂（场）。因此,我们要明确屠宰检疫与肉品品质检验的关系。屠宰检疫是在屠宰加工过程中,对动物的胴体、头、蹄、内…     

中华人民共和国农业农村部公告（第637号）

<正>为规范生猪屠宰肉品品质检验，保障生猪产品质量安全，根据《生猪屠宰管理条例》规定，我部组织制定了《生猪屠宰肉品品质检验规程（试行）》，现予公布，自公布之日起施行。特此公告。2023年1月3日生猪屠宰肉品品质检验规程（试行）1适用范围本规程规定了生猪屠宰过程中肉品品质检验的内容、程序、方法及处理。     

国务院发布《生猪屠宰管理条例》

为了加强生猪屠宰管理．保证生猪产品质量．保障人民身体健康．国务院近日发布《生猪屠宰管理条例》．对生猪实行定点屠宰、集中检疫、统一纳税、分散经营的制度。该条例对生猪定点屠宰、生猪检疫及定点屠宰厂应具备的条件等问题作出明确规定,条例第七条规定：定点屠宰厂（场）应当具备下列条件：1.有与屠宰规模相适应,水质符合国家规定标准的水源条件；2．有符合国家规定要求的待宰间、屠宰间、急宰间以及生猪屠宰设备和运载工具；3．有依法取得健康证明的屠宰技术人员；4．有经考核合格的专职或者兼职的肉品品质检验人员；5．有必要的检验…     

《肉品品质检验合格主》制度应予取消

1999年以来,我市部分区、县(自治县、市)相继在定点屠宰场生猪实施肉品品质检验后,加盖肉品品质检验验讫印章,同时出具《肉品品质检验合格证》.我们认为,出具《肉品品质检验合格证》这种作法,没有法律法规依据,已违反了《中华人民共和国动物防疫法》和《生猪屠宰管理条例》的规定,实行后已严重干扰我市屠宰检疫管理工作秩序,影响畜产品流通和正常的肉品市场秩序.     

四川省将压缩生猪屠宰场所 定点屠宰规范“源头”

四川省商务厅近日发出《关于进一步做好防控猪链球菌病疫情，加强生猪屠宰管理和市场供应工作的通知》，要求各级商务部门加强生猪定点屠宰管理，对生猪屠宰厂（场）进行全面检查，加强猪肉检疫和肉品品质检验，确保定点屠宰场所内检验检疫率达到100%，从源头保证上市猪肉安全。     

生猪肉品质量检验亟待加强

正根据《生猪屠宰管理条例》规定,企业检验人员应当根据国家检验规程对生猪产品进行检验,检验合格的方可出厂销售。据调查,目前不少生猪屠宰企业存在着质量管理制度缺失,质量意识薄弱,检验人员缺乏,检验技能低等问题,质量安全存在隐患,亟待加强。一、生猪屠宰企业品质检验状况1.检验人员不足。根据《生猪定点屠宰厂资质等级要求》(SB/T10396-2011)规定,一个年屠宰10万头(70头/小时)以上的屠宰厂,

商会自治的基石——商会自治规范研究

在现代法律秩序中,商会自治规范是制定法的基础和必要的补充,甚至在某些方面替代了制定法;商会自治规范主要包括商会组织规范、行为规范、惩罚规范以及争端解决规范等;其效力仅及于其内部成员;商会自治规范和制定法之间存在冲突,但也存在整合的基础。

鸡败血支原体垂直传播模式及其阻断方法

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。     

Comparison of 2 methods of centesis of the bursa of the biceps brachii tendon of horses

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.

乳酸杆菌益生作用机制的研究进展

乳酸杆菌作为益生菌广泛用于人和动物。本文综述了乳酸杆菌改善宿主健康的机制。乳酸杆菌可通过产生抗菌物质如乳酸、过氧化氢、细菌素,或者通过竞争营养或肠道黏附位点来抑制致病菌;通过诱导黏附素的分泌或阻止细胞凋亡而增强肠道的屏障功能,从而保护肠道。文章重点讨论了乳酸杆菌表面成分（表面蛋白、脂磷壁酸和肽聚糖）与肠道受体（Ｃ型凝集素受体、Ｔｏｌｌ样受体和 Ｎｏｄ样受体）,阐述了他们结合后启动免疫调节信号,调控肠道免疫功能以发挥改善健康作用的机制。     

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.
