“…3,22 Similar to other hospital outbreaks of infection caused by different Salmonella species, we had no evidence of transmission from healthcare workers to patients, despite the proximity of a patient population at high risk for acquiring invasive Salmonella disease. 31,32 This study had a few limitations. The case-control study design is subject to recall bias, with case subjects potentially more motivated than control subjects to recall foods they ate.…”

Objective.To determine the source of an outbreak of Salmonella javiana infection.Design.Case-control study.Participants.A total of 101 culture-confirmed cases and 540 epidemiologically linked cases were detected between May 26, 2003, and June 16, 2003, in hospital employees, patients, and visitors. Asymptomatic employees who had eaten in the hospital cafeteria between May 30 and June 4, 2003, and had had no gastroenteritis symptoms after May 1, 2003, were chosen as control subjects.Setting.A 235-bed academic tertiary care children's hospital.Results.Isolates from 100 of 101 culture-confirmed cases had identical pulsed-field gel electrophoresis patterns. A foodhandler with symptoms of gastroenteritis was the presumed index subject. In multivariate analysis, case subjects were more likely than control subjects to have consumed items from the salad bar (adjusted odds ratio [aOR], 5.3; 95% confidence interval [CI], 2.3-12.1) and to have eaten in the cafeteria on May 28 (aOR, 9.4; 95% CI, 1.8-49.5), May 30 (aOR, 3.6; 95% CI, 1.0-12.7), and/or June 3 (aOR, 4.0; 95% CI, 1.4-11.3).Conclusions.Foodhandlers who worked while they had symptoms of gastroenteritis likely contributed to the propagation of the outbreak. This large outbreak was rapidly controlled through the use of an incident command center.

“…Contamination offood by the hands offood handlers is unusual if proper hygiene is practised, 3 -5 but when this is breached, outbreaks can also occur. 6 Outbreaks of salmonellosis in hospitals are of special concern as there is an increased susceptibility of patients, with an associated morbidity. Outbreaks and their control measures can seriously disrupt hospital services.…”

“…foodhandler is unusual if proper hygiene is practiced,3-6 but when this is breached, outbreaks occur. 7 In Jordan, Al-Laham et al8 found that 48% of non-Jordanian and 12% of Jordanian foodhandlers harbored enteropathogens. The impact of these foodhandlers on outbreaks of food poisoning in Jordan has yet to be determined.…”
