This article provides new estimates of the cost of U.S. foodborne illness. Our research updated disease modeling underlying these cost estimates with a focus on enhancing chronic sequelae modeling and enhancing uncertainty modeling. Our cost estimates were based on U.S. Centers for Disease Control and Prevention estimates of the numbers of foodborne illnesses, hospitalizations, and deaths caused by 31 known foodborne pathogens and unspecified foodborne agents. We augmented these estimates of illnesses, hospitalizations, and deaths with more detailed modeling of health outcomes, including chronic sequelae. For health outcomes, we relied on U.S. data and research where possible, supplemented by the use of non-U.S. research where necessary and scientifically appropriate. Cost estimates were developed from large insurance or hospital charge databases, public data sources, and existing literature and were adjusted to 2023 dollars. We estimated the cost of foodborne illness in the United States circa 2023 to be $75 billion. Deaths accounted for 56% and chronic outcomes for 31% of the mean cost. The costliest pathogen was nontyphoidal <i>Salmonella</i> at $17.1 billion followed by <i>Campylobacter</i> at $11.3 billion. <i>Toxoplasma</i> ($5.7 billion) and <i>Listeria</i> ($4 billion) followed due primarily to deaths and chronic outcomes from pregnancy-associated cases. Per-case cost ranged from $196 for <i>Bacillus cereus</i> to $4.6 million for <i>Vibrio vulnificus.</i> Unspecified agents accounted for 38% of the total cost of foodborne illness, but these illnesses were generally mild (per-case cost $781). These cost estimates can help inform food safety priorities. Our pathogen-specific per-case cost estimates can also help inform benefit-cost analysis required for new federal food safety regulations.</p>","PeriodicalId":12333,"journal":{"name":"Foodborne pathogens and disease","volume":null,"pages":null},"PeriodicalIF":1.9,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142361384","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Inactivating <i>E. granulosus</i> protoscoleces through heating, cooling, or chemicals such as sodium chloride can be considered an effective method for controlling hydatidosis in both humans and animals. The main objective of this study was to evaluate the effect of different temperatures and salinity conditions on the survival of <i>Echinococcus granulosus</i> protoscoleces. For this purpose, 50 g of infected liver (in triplicate) was separately treated with different temperatures (+10°C, +50°C, +60°C, +72°C, and -20°C) and concentrations of sodium chloride (5%, 10%, 15%, and 20%) for 3, 6, 12, 24, 48, and 72 h. Additionally, 50 g of infected liver was stored separately in the refrigerator (+4°C) as a control group. The survival rate of the protoscoleces was evaluated by staining with 1% eosin under a light microscope. The results showed that the protoscoleces were significantly affected, with 100% mortality at -20°C after 0.5 h, and complete death at +72°C, +60°C, +50°C, and +10°C after 1, 1.5, 3, and 24 h, respectively (<i>p</i> < 0.005).
