The Economic Impact of Listeria Infections
The overall cost estimates for Listeria infections in the U.S. run from $61.7 to $64.8 million yearly.
The USDA Economic Research Service (ERS) published its first comprehensive cost estimates for sixteen foodborne bacterial pathogens in 1989.  Five years later, it was estimated that, in 1993, there were 1,795 to 1,860 Listeria infections that required hospitalization, with 295-360 of these cases involving pregnant women.  Based on these estimates, the medical costs that Listeria infections had caused each year were said to run from $61.7 to $64.8 million, including those individuals who ultimately died as a result of their infections. 
For these same acute cases, productivity costs were estimated to run from $125.8 to $154.4 million a year.  The productivity costs associated with Listeria-related chronic illness was estimated to be an additional $38 million a year.  In sum, “[e]stimates of total costs for the 1,795 to 1,860 cases of listeriosis range from $232.7 million to $264.4 million annually.” 
In 2000, USDA updated the cost-estimates for four pathogens: Campylobacter, Salmonella, E. coli O157:H7, and Listeria monocytogenes. [28a] The 2000 estimates were based on the CDC’s then newly-released estimates of annual foodborne illnesses, and put the total cost in the United States for these four pathogens at $6.5 billion a year. [28a] For Listeria specifically, it was estimated that costs amounted to $2.3 billion per year, based on 2,493 cases, which involved 2,298 hospitalizations and 499 deaths. [28a] More recently, in 2007, it was estimated that the worldwide cost of all foodborne disease was $1.4 trillion per year.
