“…The reasons for this difference are not known. The simplified biotyping system of Devriese [4] for typing S. aureus has been useful in tracing the origin of this organism in animal food and in food industry [6,9,10,12,19]. The raw chicken meat examined in the present study was primarily contaminated by S. aureus belonging to the poultry biotype, suggesting that the isolates originate probably from live chickens.…”

ABSTRACT. A total of 444 samples of raw chicken meat (thighs, breasts, wings, livers, gizzards, hearts and ovaries) that retailed at 145 different supermarkets in 47 prefectures in Japan were examined for contamination with Staphylococcus aureus in association with its enterotoxigenicity. S. aureus was isolated from 292 (65.8%) of the samples, and from 131 of the 145 supermarkets. There was no significant difference in the detection rate of S. aureus according to the type of meat examined. About 80% of 714 isolates belonged to the poultry (57.1%) and human biotypes (22.1%). Seventy-eight (21.7%) of 360 isolates were enterotoxigenic and isolated from 78 samples in 53 supermarkets in 31 prefectures. Staphylococcal enterotoxins (SEs) produced were SEB (50 isolates), SEA (14), SEC (8), SED (2), SEA+SEB (2), and SEA+SEC (2). Most of the enterotoxigenic isolates belonged to the human and poultry biotypes, coagulase type VII, VIII or IV, and were lysed by phages of group III. Identical SE types, biotypes, coagulase types and pulsed-field gel electrophoresis (PFGE) patterns were shown in isolates from different types of meat at the same supermarket and from samples taken from different supermarkets in the same prefectures or in isolates from samples obtained from several different prefectures. Among the 50 SEB-producing isolates, 27 yielded three similar PFGE patterns that differed by only a few fragments, suggesting that they were closely related genetically. The three patterns were found in isolates of samples that retailed at 17 supermarkets in 11 prefectures, indicating that they may be disseminated among raw chicken meat in Japan. KEY WORDS: biotype, coagulase type, pulsed-field gel electrophoresis, Staphylococcus aureus, staphylococcal enterotoxin.

“…Biotyping: Biotyping was carried out according to the simplified system established by Devriese et al [4,6,10], which uses four tests: the production of staphylokinase and β-hemolysin, coagulation of bovine plasma within 6 hr, and the type of growth on crystal violet agar.…”

“…However, 86-6 % of the S. aureus strains produced enterotoxins. This figure was higher than that reported by Isigidi and colleagues [24] and Sokari [25]. The result is important for the restaurant industry because it may take only a single carrier to contaminate food with an enterotoxin-producing strain to start an outbreak [9,19].…”

Nasal carriage of enterotoxin-producingStaphylococcus aureusamong restaurant workers in Kuwait City

SUMMARYEnterotoxin-producing Staphylococcus aureus is a common cause of staphylococcal food poisoning. To determine the incidence of carriage of enterotoxin-producing S. aureus in a sample of the healthy population in Kuwait city, restaurant workers in the city were screened for nasal carriage of S. aureus. 26-6% of 500 workers studied carried S. aureus and 86-6% of the S. aureus produced staphylococcal enterotoxins. 28 % produced enterotoxin A, 28&5 % produced enterotoxin B, 16-4% produced enterotoxin C and 355% produced enterotoxin D. Ten isolates produced both enterotoxins A and B or A and C. 73 % of the isolates were untypeable with standard phages. However, 17 1 %, 3 % and 6% belonged to phage groups I, II and III respectively. The results demonstrated a high level of enterotoxigenic S. aureus carriage among restaurant workers which although lower than that reported for the general population and hospital workers may be important in the restaurant industry.
