在分析的168份水产品和87份来自鱼类加工厂工人的样品中，分别有21份（17%）和54份（62%）被发现产肠球菌性金黄色葡萄球菌阳性。在这些产品中，冷冻去皮未去血管（PUD）对虾和冷冻鱼片（各33%）的发病率高于冷冻去皮和去血管（PD）对虾和冷冻鱿鱼（分别为25%和20%）。从产品中分离的51株菌株中有21株（41%）和从加工工人中分离的54株菌株中有15株（28%）被发现是肠球菌。产品中以葡萄球菌肠毒素C（SEC）为主（57%），其次为葡萄球菌肠毒素A（SEA）（43%），工人中以葡萄球菌肠毒素B（SE B）、葡萄球菌肠毒素C（SEC）和葡萄球菌肠毒素A（SEA）为主（SE B、SEC、SEA），分别占40%、40%和20%）。
Of the 168 fishery products and 87 samples from fish processing factory workers analyzed, 21 (17%) and 54 (62%) were found positive for enterotoxigenic Staphylococcus aureus, respectively. Among the products, incidence was high in frozen peeled un-deveined (PUD) prawns and frozen fish cutlets (33% each) compared to frozen peeled and deveined (PD) prawns and frozen squids (25% and 20%, respectively). 21 out of 51 strains (41%) isolated from products and in 15 out of 54 strains from processing workers (28%) were found to be enterotoxigenic. The enterotoxin type Staphylococcal enterotoxin C (SEC) (57%) was predominated followed by Staphylococcal enterotoxin A (SEA) (43%) in products and Staphylococcal enterotoxin B (SEB) (40%), Staphylococcal enterotoxin C (SEC) (40%) and Staphylococcal enterotoxin A (SEA) (20%) in workers.
