“…Richards and colleagues [9] found that the enterotoxin-producing S. aureus strains isolated from 18 students after an episode of staphylococcal food poisoning were similar to an isolate from a single food handler in the kitchen where the lunches were prepared. Although S. aureus produces six different types of enterotoxins, A-E, enterotoxin A is commonly associated with food poisoning [9,14,22,23]. In this study enterotoxin A was detected in 28&5 % of the isolates (Table 1).…”

“…Some strains produce one or more of six serologically related enterotoxins designated A, B, C1, C2, D and E [11][12][13]. Ingestion of the preformed toxins in contaminated foods leads to the rapid development of vomiting and diarrhoea, the characteristic symptoms of staphylococcal food poisoning [11,12,14,15]. Staphylococcal enterotoxins are heat stable and can * Author for correspondence.…”

“…Enterotoxin-producing S. aureus is an important cause of food poisoning in many parts of the world [11][12][13][14][15]. It accounts for 14-20% of outbreaks involving contaminated food in the USA [8], and in the United Kingdom restaurants are the second most important place for acquiring staphylococcal food poisoning [10].…”

“…Food poisoning outbreaks also result in huge financial losses to restaurants plus the loss of reputation and confidence by the public. It also impacts on society through loss of productive hours by the sick [14].…”

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.

“…aureus is capable of producing various toxins and extracellular products [6]. Some toxins are recognised to be associated with specific clinical conditions such as food poisoning, [7] scalded skin syndrome, [8] toxic shock syndrome [9] and the recalcitrant erythematous desquamating disorder [ 1 01.…”

This study compared specific phenotypic and potential virulence characteristics of StaphyZococcus aureus isolates from invasive infections and nasal carriers. Three hundred and sixty isolates were studied; 154 from septicaemia (69 line associated, 85 non-line), 79 from continuous ambulatory peritoneal dialysis (CAPD) peritonitis, 64 from bone/joint infections and 64 from healthy nasal carriers. The isolates were tested for production of enterotoxins (SE) A, B, C or E, toxic shock syndrome toxin-1 (TSST-1) protein A, and also for lipolytic, proteolytic, fibrinolytic and haemolytic activities. In addition phage typing, crystal violet reaction, urease and galactose breakdown were studied. Seventy-one percent of isolates were enterotoxigenic. Production of SEA was significantly lower amongst the bone/joint isolates. Production of SEB, was lower among the control group compared with CAPD, bone/joint, and non-line septicaemia isolates. SEE production was higher among the bone/joint isolates compared with the CAPD and non-line septicaemias and production of TSST-1 was significantly higher among nasal isolates compared with isolates causing infection. Almost all of the isolates were lipolytic, with highest activity amongst nasal and bone/ joint isolates. Fibrinolytic activity was similar in the five groups of isolates. Proteolytic activity ranged from 35 to 62% of isolates with the lowest frequency among septicaemia isolates. In all, 80-90% of isolates were haemolytic, although CAPD isolates were less likely to be haemolytic. Isolates from the control and CAPD group more frequently belonged to phage group I. TSST-1 does not appear to be an important requirement for invasive infections, but SEB may be. Proteolysis and intensity of lipolysis appear to be less important in septicaemia, and haemolysis may not be important in CAPD pertonitis.
