Salmonellosis is an infection caused by the bacterium Salmonella. A study monitored outbreaks associated with different contaminated food sources. The following data shows the number of people who contracted the infection (cases) and the number of those cases that resulted in hospitalization: Poultry (820 cases, 164 hospitalizations), Eggs (450 cases, 108 hospitalizations), Sprouts (250 cases, 45 hospitalizations), Ground beef (640 cases, 112 hospitalizations), and Pork (380 cases, 68 hospitalizations). The likelihood of a patient being hospitalized depends on the food source from which the bacterium came. Determine which food source is most likely to lead to hospitalization. Show your working.
