Fourteen Complaints Linked to Cut Fruit Salad
On a Friday, the customer-service desk at your store receives 14 complaints over six hours. All 14 customers bought the store-made fresh cut fruit salad between Monday and Wednesday. They report diarrhea, abdominal cramps, and fever beginning 26 to 38 hours after eating; three report bloody stools. The fruit salad is made in the produce room from cantaloupe, honeydew, grapes, and strawberries, and is sold in 12-ounce cups with a four-day use-by date. The produce room also receives whole raw chicken for the adjacent meat department through a shared back corridor, but not through the produce room. Two produce employees have called out with diarrhea this week. The store has no retained samples, and the fruit salad batch is sold out. A local restaurant also bought 20 cups for a Monday event and reports two ill staff. Your store director asks whether you should issue a recall.
1. Based on the incubation period and symptoms, what hazards fit, and what does that imply about the investigation?
Read the worked answer
The incubation period is the main clue. Onset of 26 to 38 hours with fever, cramps, and bloody stools fits Salmonella, Shigella, or Shiga toxin-producing E. coli more than norovirus or Staphylococcus aureus. Norovirus usually produces vomiting with a 12- to 48-hour onset and fever is less prominent; S. aureus is 1 to 7 hours with severe vomiting. The implication is that this is likely a bacterial pathogen with a relatively low infectious dose, so the investigation should focus on cross-contamination, inadequate washing of cantaloupe, ill produce workers, and shared equipment, not on whether the fruit looked spoiled. The restaurant cluster strengthens the link to a common lot. You should not wait for laboratory results to act, and you should not assume the fruit itself was the source until you compare the production dates with the employees' illness dates.
2. What are your immediate actions in the first two hours?
Read the worked answer
First, stop sale and hold all remaining fruit salad and the components from the implicated lots. Second, notify the local regulatory authority and start a complaint log with names, phone numbers, purchase dates, onset times, and symptoms. Third, interview the two produce employees with diarrhea and exclude them from food work. Fourth, review the produce-room process: cantaloupe washing, sanitizer concentration, cutting boards, utensils, handwashing, and whether raw chicken ever passes through. Fifth, contact the restaurant to hold its remaining cups. Sixth, do not issue a broad public recall until you confirm the product is still in commerce, but a withdrawal and hold are immediate. The store director should be told that a recall is a regulatory decision made with the health department, and that sold-out status does not remove the need to notify.
3. What trace-back and records do you need, and what question are you trying to answer?
Read the worked answer
Trace-back means lot codes and receiving dates for cantaloupe and other fruit, supplier names, invoices, and the production log showing who made each batch and when. Compare the production dates of the implicated cups with the employees' illness dates. Collect the produce-room sanitizer log and test strips, cutting-board cleaning schedule, and handwashing records. Preserve the packaging and any leftover product; if the restaurant has cups, arrange pickup through the health department. Interview all produce staff about recent illness, including those who did not call out. The key question is whether contamination came in on the fruit, from an ill worker's hands, or from equipment, because each points to a different corrective action. The answer also determines whether the supplier or the store bears responsibility.
