【摘要】：本文對漯河地區(qū)不同地點(diǎn)的豬肉市場的豬旋毛蟲和弓形蟲的感染情況做了一個詳細(xì)的調(diào)查,具體研究內(nèi)容及結(jié)論如下:在對豬肉旋毛蟲感染情況調(diào)查中,共采集2238份豬肉樣品,通過顯微鏡檢驗(yàn),發(fā)現(xiàn)2238份豬肉樣品中,有8份為旋毛蟲陽性包囊,總檢測率為0.36%(8/2238);通過PCR檢測,發(fā)現(xiàn)2238份豬肉樣品中,在PCR擴(kuò)增結(jié)果中有12份為擴(kuò)增陽性,總檢測率為0.54%(12/2238)。其中,在7個豬肉銷售地點(diǎn)中,共發(fā)現(xiàn)3個地點(diǎn)有感染情況,城鎮(zhèn)菜市場1檢測率為0.26%(1/386),城鎮(zhèn)菜市場1檢測率為2.25%(9/400),市內(nèi)菜市場2檢測率為0.78%(2/258),而在其余4個地點(diǎn)均沒有發(fā)現(xiàn)豬肉旋毛蟲感染情況。在對豬肉弓形蟲感染情況調(diào)查中,作者又多采集300份樣品,共采集2538份豬肉樣品,通過顯微鏡檢驗(yàn),發(fā)現(xiàn)2538份豬肉樣品中,有3份為弓形蟲陽性包囊,總檢測率為0.12%(3/2538);通過PCR檢測,發(fā)現(xiàn)2538份豬肉樣品中,在PCR擴(kuò)增結(jié)果中有26份為擴(kuò)增陽性,總檢測率為1.0%(26/2538)。其中,在9個豬肉銷售地點(diǎn)中,共發(fā)現(xiàn)3個地點(diǎn)有感染情況,城鎮(zhèn)菜市場2檢測率為0.5%(2/400),豬肉制品加工廠1檢測率為9.49%(15/158),豬肉制品加工廠2檢測率為6.33%(9/142),而在其余6個地點(diǎn)均沒有發(fā)現(xiàn)豬肉弓形蟲感染情況對于旋毛蟲,弓形蟲防控方面:旋毛蟲無耐熱性,豬肉經(jīng)高溫后可安全無害�？茖W(xué)加工肉品,不要吃生的、或者未加工熟的豬肉以及被鼠糞等污染的食物,切肉刀具要生熟分開。豬弓形蟲病是國家規(guī)定B類傳染病,一旦發(fā)現(xiàn),不能上市,必須化制或銷毀。為了預(yù)防弓形蟲病:貓是該病的主要傳播者,孕婦盡量不養(yǎng),做好孕前、孕中檢查;提高醫(yī)務(wù)人員對本病的認(rèn)識及掌握本病的診斷和治療方法。對人群和動物感染情況及其有關(guān)因素進(jìn)行調(diào)查,以便制定切實(shí)可行的防治措施;做好水、糞等管理工作,要特別注意防止可能帶有弓形體卵囊的貓糞污染水源,食物和飼料等。本實(shí)驗(yàn)證明河南省漯河地區(qū)菜市場商品豬肉中存在有豬旋毛蟲病和弓形蟲病感染情況。并且發(fā)現(xiàn)城鎮(zhèn)地區(qū)要比市區(qū)流行,發(fā)病率高。因此,動物檢疫人員應(yīng)對屠宰場特別是城鎮(zhèn)屠宰場繼續(xù)加強(qiáng)豬肉的旋毛蟲和弓形蟲檢疫工作,采取相應(yīng)的防控措施,以保證漯河地區(qū)肉及肉食品的安全性。
[Abstract]:This paper makes a detailed investigation on the infection of trichinella spiralis and Toxoplasma gondii in the pork market in Luohe area. The specific contents and conclusions are as follows: 2238 pork samples were collected in the investigation of the infection of trichinella spiralis. Microscopic examination showed that 8 out of 2238 pork samples were positive for Trichinella spiralis, and the total detection rate was 0.36% (8 / 2238). PCR analysis showed that 12 out of 2238 pork samples were positive for PCR amplification, and the total detection rate was 0.54% (12 / 2238). Among them, in 7 pork sales sites, 3 sites were found to be infected. The detection rate of vegetable market 1 was 0.26% (1 / 386), and that of vegetable market 1 was 2.25% (9 / 400) in urban vegetable market, and the detection rate was 0.26% (1 / 386) in urban vegetable market, and 2.25% (9 / 400) in urban vegetable market. The detection rate was 0.78% (2 / 258) in the local vegetable market, but no infection of the pork trichinella was found in the other four locations. In the investigation of the infection of Toxoplasma gondii in pork, the author collected 300 more samples and 2538 pork samples. Through microscope examination, 3 of 2538 pork samples were found to be Toxoplasma gondii positive cyst. The total detection rate was 0.12% (3 / 2538); PCR analysis showed that 26 out of 2538 pork samples were positive for PCR amplification, and the total detection rate was 1.0% (26 / 2538). Among them, in 9 pork sales sites, a total of 3 sites were found to be infected. The detection rate of vegetable market 2 in urban areas was 0.5% (2 / 400), and that of pork product processing factory 1 was 9.49% (15 / 158). The detection rate of pork product processing factory 2 was 6.33% (9 / 142), but no infection of Toxoplasma gondii was found in the other 6 sites. In terms of prevention and control of Trichinella spiralis, Toxoplasma gondii: Trichinella spiralis has no heat resistance. Pork can be safe and harmless after high temperature. Scientific processing of meat, do not eat raw, or raw pork and food contaminated with rat dung, meat cutters should be cooked apart. Swine toxoplasmosis is a class B infectious disease specified by the state. In order to prevent toxoplasmosis: cat is the main transmission of the disease, pregnant women do not raise as much as possible, do well before pregnancy, pregnant examination, improve the medical staff understanding of the disease and grasp the diagnosis and treatment of the disease. To investigate the infection of people and animals and its related factors in order to make feasible measures for prevention and cure, and to do well the management of water and feces, special attention should be paid to preventing the contamination of water, food and feed from cat dung which may contain toxoplasma oocysts. The results showed that there were trichinellosis and Toxoplasma gondii infection in the commercial pork in Luohe area of Henan Province. And found that urban areas are more prevalent than urban areas, the incidence of high. Therefore, animal quarantine personnel should continue to strengthen the quarantine of trichinella and Toxoplasma gondii in slaughterhouses, especially in urban slaughterhouses, and take corresponding prevention and control measures to ensure the safety of meat and meat food in Luohe area.
