Gumbo A, Bangure D, Gombe NT, Mungati M, Tshimanga M, Hwalima Z, Dube I - BMC Res Notes (2015)

Bottom Line: Eating stewed chicken (RR = 2.52, 95% CI 1.30-4.89) served at hour 13:00 during lunch on August 20, 2014 at Ikhwezi Training Centre was the only significant risk factor associated with food poisoning.Drinking purified bottled water [RR = 0.67, 95% CI (0.57-0.79)] was found to be protective.Training of food handlers in basic food hygiene and safety is recommended.

ABSTRACT

Background: Bulawayo City Council held an Integrated Result Based Management workshop among 86 employees from August 18-22, 2014 at Ikhwezi Training Centre in Bulawayo City. On August 21, 2014, a report of diarrhoea among Council employees attending the workshop was received. We investigated the outbreak to determine the risk factors associated with diarrhoea at Ikhwezi Training Centre, Bulawayo City.

Method: A retrospective cohort study was conducted where 74 Council employees were interviewed on food consumed and presenting signs and symptoms. Stool specimens and hand swabs were collected for culture. Water samples were collected for bacteriological analysis. Food samples were not available. Data were analysed using Epi Info™ to generate frequencies, means, proportions, risk ratios, and attributable risk.

Results: Of the 74 employees interviewed 34 (45.9%) were males and 40 (54%) were females. The response rate was 94%. The common signs and symptoms included abdominal cramps (88.7%), and watery diarrhoea (86.8%). The overall attack rate was 71.6%. Eating stewed chicken (RR = 2.52, 95% CI 1.30-4.89) served at hour 13:00 during lunch on August 20, 2014 at Ikhwezi Training Centre was the only significant risk factor associated with food poisoning. Drinking purified bottled water [RR = 0.67, 95% CI (0.57-0.79)] was found to be protective. Staphylococcus aureus was isolated from the hands and nails of food handlers.

Conclusion: The outbreak was due to food poisoning and was most likely caused by the Staphylococcus aureus formed toxins. Stewed chicken served during lunch on August 20, 2014 was the possible source of infection. Contamination might have occurred during food handling and preparation. Training of food handlers in basic food hygiene and safety is recommended.

Mentions: Figure 1, illustrates the onset of illness over time. The onset of Illness for the first case was reported between 3 and 4 p.m. on the 20th of August 2014 after having eaten lunch served at 1300 h and cases continued to be reported between 5 and 6 p.m. reaching the first peak. There was a decline between 7 and 8 p.m. followed by a rise between 9 and 10 p.m. reaching the second peak. A decline was also noted between 1 and 2 a.m., followed by a rise between 3 and 4 and reaching the third peak. Cases began to decline until 10 a.m. on August 21, 2014 August. The median incubation period from the time lunch was served was 11 h (Q1 = 7; Q3 = 16).Fig. 1
