【摘要】：目的了解淮安市生畜禽肉和即食性淡水龙虾中致病菌的污染状况以及相关菌株的耐药性,为食源性疾病预防工作提供依据。方法依据国家食品微生物检测标准检测233份生畜禽肉和152份即食性淡水龙虾产品中的致病菌,然后测定相关致病菌的耐药性。结果生畜禽肉中致病菌检出率为21.03%(49/233),即食性淡水龙虾产品中致病菌检出率为3.95%(6/152)。分离到的致病菌包括沙门氏菌(32株)、金黄色葡萄球菌(19株),单增李斯特菌(5株)和副溶血弧菌(4株)。沙门氏菌和金黄色葡萄球菌分离株的耐药情况严重。其中,沙门氏菌分离株主要对氨苄西林和萘啶酸具有耐药性,分别为78.13%和81.25%;金黄色葡萄球菌分离株则对红霉素(94.74%)、甲氧苄氨嘧啶/磺胺甲VA唑(84.21%)和克林霉素(63.16%)具有较强的耐药性。结论淮安市生畜禽肉和即食性淡水龙虾中致病菌污染严重,且沙门氏菌和金黄色葡萄球菌耐药性严重。相关部门应该加强市场监督并建立食品致病菌持续监测机制,预防食源性疾病的暴发。
[Abstract]:Objective to investigate the contamination of pathogenic bacteria in raw livestock and poultry meat and instant freshwater lobster in Huaian city and the drug resistance of related strains. Methods 233 samples of raw animal meat and 152 samples of instant fresh water lobster products were detected for pathogenic bacteria according to the national food microbial detection standard. The results showed that the detection rate of pathogenic bacteria in raw animal meat was 21.03%. The detection rate of pathogenic bacteria in instant freshwater lobster products was 3.95 / 1520.The pathogenic bacteria isolated included 32 strains of salmonella and 19 strains of Staphylococcus aureus). 5 strains of Listeria monocytogenes) and 4 strains of Vibrio parahaemolyticus. The drug resistance of Salmonella and Staphylococcus aureus isolates were serious. Salmonella isolates were mainly resistant to ampicillin and naphthalic acid (78.13% and 81.25, respectively). Staphylococcus aureus isolates were compared with erythromycin (94.74%). Trimethoprim / sulfamethazolium (84.21) and clindamycin (63.16) have strong drug resistance. Conclusion the contamination of pathogenic bacteria in raw livestock and poultry meat and instant freshwater lobster in Huaian City is serious. The drug resistance of Salmonella and Staphylococcus aureus is serious. The relevant departments should strengthen the market supervision and establish a continuous monitoring mechanism of food pathogenic bacteria to prevent the outbreak of foodborne diseases.

【正文快照】： 由食源性致病菌导致的食源性疾病是全球范围内致死率较高的疾病之一,因此国内外对于食品卫生安全问题日益关注[1]。目前,在临床治疗和畜牧业生产中,对付各种病原菌的首选药物仍然是抗生素,但是抗生素的滥用所产生的选择性压力使得很多病原菌出现了耐药以及多重耐药现象[2]。为
