  • Essay / Critical appraisal of the epidemiological study - 2132

    Study objectives and designAn outbreak of Salmonella Saintpaul (S. Saintpaul) in Australia led to an investigation to uncover the cause of the increase in the number of human infections. The outbreak occurred in six Australian jurisdictions, with its epicenter in the southeast of the continent between September and November 2006 (Munnoch et al., 2009). Cases were confirmed by isolation of the S. Saintpaul strain from a fecal sample, through routine surveillance detection (Munnoch et al., 2009). Investigators were motivated by the urgency to discover the cause of infection; previous outbreaks associated with the consumption of fresh produce amounted to 2.4%, and 28 outbreaks were caused by the consumption of cantaloupe at the internationally (Munnoch et al., 2009). The investigators also planned to identify open and responsive suggestions for public health control measures to control risk factors. The aim of the study was to test whether S. Saintpaul infection was associated with fresh produce, specifically cantaloupe, also called rock melon. . The hypothesis generated by the researcher was that fresh foods commonly consumed by people with the S. Saintpaul strain in the fecal samples were the cause of the infection, including these foods; cantaloupe, cucumber, pear, grapes, strawberries and cooked broccoli (Munnoch et al., 2009). The research hypothesis formulated by the investigators is clear and leaves little or no room for ambiguity. Researchers observed a high frequency of consumption of fresh produce by reported cases such as S. Saintpaul, hence the hypothesis that fresh food was the source of the infection. That's why researchers set out to study the link between fresh foods and S. Saintpaul infection, which allowed the research... middle of article... to end the 'epidemic. Generalizing the study does not necessarily mean applying it to another population; in this study, the relevance of the results for other populations may depend. The fact that the outbreak was due to contamination of cantaloupe during the production process may be a lesson for other populations to increase regulation and control of fresh produce production. Additionally, this study can be used as a guide to educate populations on how to prevent increased food contamination, as well as how to prevent food poisoning. Finally, the knowledge derived from the study is not necessarily new, since other studies have been done to associate the consumption of contaminated cantaloupe with illness. On the other hand, this study provides more evidence for increased monitoring and control of fresh food products during production to prevent contamination..
