Abstract

Objectives: Although outbreaks of restaurant-associated foodborne illness occur periodically and make the news, a restaurant may not be aware of the cost of an outbreak. We estimated this cost under varying circumstances.

Methods: We developed a computational simulation model; scenarios varied outbreak size (5 to 250 people affected), pathogen (n = 15), type of dining establishment (fast food, fast casual, casual dining, and fine dining), lost revenue (ie, meals lost per illness), cost of lawsuits and legal fees, fines, and insurance premium increases.

Results: We estimated that the cost of a single foodborne illness outbreak ranged from $3968 to $1.9 million for a fast-food restaurant, $6330 to $2.1 million for a fast-casual restaurant, $8030 to $2.2 million for a casual-dining restaurant, and $8273 to $2.6 million for a fine-dining restaurant, varying from a 5-person outbreak, with no lost revenue, lawsuits, legal fees, or fines, to a 250-person outbreak, with high lost revenue (100 meals lost per illness), and a high amount of lawsuits and legal fees ($1 656 569) and fines ($100 000). This cost amounts to 10% to 5790% of a restaurant's annual marketing costs and 0.3% to 101% of annual profits and revenue. The biggest cost drivers were lawsuits and legal fees, outbreak size, and lost revenue. Pathogen type affected the cost by a maximum of $337 000, the difference between a Bacillus cereus outbreak (least costly) and a listeria outbreak (most costly).

Conclusions: The cost of a single foodborne illness outbreak to a restaurant can be substantial and outweigh the typical costs of prevention and control measures. Our study can help decision makers determine investment and motivate research for infection-control measures in restaurant settings.

Impact of key parameters on the cost of restaurant-associated foodborne illness outbreaks from the restaurant perspective for (a) fast-food, (b) fast-casual, (c) casual-dining, and (d) fine-dining restaurants. The x-axis shows the total cost of an outbreak; the vertical line indicates the cost for which all variables on the y-axis are held at their midpoint values. The width of the bar shows the range of impact each parameter had when varied from its minimum value to its maximum value. Outbreak size (number of ill people) varied from 5 to 250; proportion of cases that are restaurant employees varied from 0% to 90%; meals lost per illness varied from 1 to 100; lawsuits and legal fees varied from $0 to $1 656 569; fines varied from $0 to $100 000; annual insurance premium varied from $545 to $6280; and increase in insurance premium varied from 5% to 75%. Fast-food restaurant: quick service, specific menu, and offers minimal to no table service. Fast-casual restaurant: specific menu between fast food and casual dining and offers minimal table service. Casual-dining restaurant: broad menu and offers table service. Fine-dining restaurant: dedicated meal courses and offers full table service.
