1) LTM, LTS, and LTG are tuna rice balls mixed with mayonnaise, soy sauce, and gochujang contaminated by L. monocytogenes; LHM, LHS, and LHG are ham rice balls mixed with mayonnaise, soy sauce, and gochujang contaminated by L. monocytogenes. 2) Total illness is the total number of illnesses generated from the scenario. The total lifespan in the scenario is 70 years (duration of exposure). 3) Mean risk of illness represents the average probability of disease based on one serving.
