Abstract

The article describes an outbreak of gastroenteritis which occurred on an oil drilling rig which operated in the Jubilee fields of Ghana (offshore Takoradi) between May 2011 and December 2013. An outbreak occurred on board approximately 10 h following a Christmas day buffet. Various Ghanaian and continental dishes were served during the occasion. Over a 3 day period, a total of 33 cases were recorded at the rig’s sick bay. In order to describe the outbreak and determine its possible association with the meals served at the buffet, this case control study was conducted. A short questionnaire was used for data collection and a line list prepared for summarising data of cases. Samples of food could not be taken but water samples from multiple points of the rig’s pipe water system were collected and cultured for coliforms. Data was analysed using Epi info version 7. Six foods appeared to be associated with the outbreak with odds ratios ranging from 1.2 to 2.7. The epidemic curve showed a propagated fashion of transmission and the outbreak was brought under control with public education on hand washing and disinfection of surfaces and door handles. The conclusion was that food items served at the buffet were not associated with the outbreak. Instead, a possible contamination of surfaces and door handles probably caused it. To prevent future occurrences, routine and regular hand washing and disinfection of surfaces and door handles is recommended.
