Sodium nitrite causes increased methemoglobin, resulting in systemic hypoxia, metabolic acidosis, and cyanosis. Since sodium nitrite is a preservative, the ingestion of foods containing an excessive amount of this substance can also cause acute intoxication up to death. The present review is aimed at guiding health professionals in the identification and management of sodium-nitrite-related intoxications and deaths. Methods: A systematic literature search was carried out on PubMed by following the PRISMA statement\u2019s criteria. A total of 35 studies with 132 cases were enrolled, and the data were cataloged in Microsoft Excel. To establish the causal correlation between sodium nitrite ingestion and death, the Naranjo Adverse Drug Reaction Probability Scale was used. Results: In addition to the small number of cases that have currently been published, the study demonstrated that there was a general methodological discrepancy in the diagnostic process. However, some interesting results have emerged, especially in post-mortem diagnostics. Conclusion: Sodium-nitrite-related deaths represent a challenge for forensic pathologists; therefore, it is important to promptly recognize the essential features and perform the necessary and unrepeatable examinations for the correct diagnosis of the cause of death.<\/jats:p>","DOI":"10.3390\/ijerph192113996","type":"journal-article","created":{"date-parts":[[2022,10,27]],"date-time":"2022-10-27T20:37:58Z","timestamp":1666903078000},"page":"13996","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":38,"title":["Sodium Nitrite Intoxication and Death: Summarizing Evidence to Facilitate Diagnosis"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-2452-7926","authenticated-orcid":false,"given":"Martina","family":"Padovano","sequence":"first","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mariarosaria","family":"Aromatario","sequence":"additional","affiliation":[{"name":"Unit of Risk Management, Quality, and Accreditation, Sant\u2019Andrea University Hospital, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3689-0001","authenticated-orcid":false,"given":"Stefano","family":"D\u2019Errico","sequence":"additional","affiliation":[{"name":"Department of Medicine, Surgery and Health, University of Trieste, 34137 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Monica","family":"Concato","sequence":"additional","affiliation":[{"name":"Department of Medicine, Surgery and Health, University of Trieste, 34137 Trieste, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Federico","family":"Manetti","sequence":"additional","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0976-5504","authenticated-orcid":false,"given":"Maria Chiara","family":"David","sequence":"additional","affiliation":[{"name":"Department of Public Security, Health Central Directorate, Research Center and Forensic Toxicology Laboratory, Ministry of the Interior, 00184 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7259-3090","authenticated-orcid":false,"given":"Matteo","family":"Scopetti","sequence":"additional","affiliation":[{"name":"Department of Medical Surgical Sciences and Translational Medicine, Sapienza University of Rome, 00189 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0358-7965","authenticated-orcid":false,"given":"Paola","family":"Frati","sequence":"additional","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1686-3236","authenticated-orcid":false,"given":"Vittorio","family":"Fineschi","sequence":"additional","affiliation":[{"name":"Department of Anatomical, Histological, Forensic and Orthopedic Sciences, Sapienza University of Rome, 00161 Rome, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,10,27]]},"reference":[{"key":"ref_1","unstructured":"World Health Organisation (2021, February 16).
