Question

Section 2 Food-Borme Outbreak One hundred and fifty people attended a charity luncheon in which two different menus were served. A total of 76 attendees reported symptoms including nausea, vomiting. cramps and diarrhea. Most of the 76 patients who sick reported symptoms about six hours after the beginning of the luncheon. The symptoms lasted from four to seven hours The dishes that were served included: baked chicken, meat loaf, mashed potatoes and green beans. The table below shows the data collected from this investigation.

Complete the table above. Calculate the attack rates and relative risk and fill in these columns in the table. Round attack rates and RRs to the hundredths. 2. There were two menus people could choose from (each with a meat and a vegetable). From the RRs you calculate above (#1), list the two food items included in each of the two menus served.

Explanation / Answer

3. To investigate and conclude for an outbreak and confirming its cause, an only attack rate is is not sufficient. Along with the attack rate, the food sample specimen are also required. Also, clinical specimens need to be collected, such as faecal samples, vomits etc. Also, the place where the food has been prepared and has been processed has to checked and examined. This would also help in identifying the pathogens along with the potential reasons for the outbreak. This can be combined with the attack rate in order to identify the responsible factor for the outbreak.

4. The relative risk value of baked chicken is the highest being 7.4. Thus, if only the relative risk is considered , then baked chicken is thought to be most responsible for the outbreak.
